You can follow the full story of my testing at CentOS Bug Tracker with 1419 id, http://bugs.centos.org/view.php?id=1419 Actually i'm running the stock kernel 42.0.3 in affected host with a lil more stability appreciated than previous kernels released but not really stable in certain situations (heavy i/o load on external usb 2.0 disk). [root@fattybox ~]# cat /etc/grub.conf | grep vmlinuz-`uname -r` kernel /vmlinuz-2.6.9-42.0.3.EL ro root=/dev/VolGroup00/LogVol00 ACPI=off vga=0x307 selinux=0 [root@fattybox ~]# dmesg | grep ACPI ACPI: Unable to locate RSDP Kernel command line: ro root=/dev/VolGroup00/LogVol00 ACPI=off vga=0x307 selinux=0 ACPI: Subsystem revision 20040816 ACPI: Interpreter disabled. What's sure, the system was running rock solid with 4.3 release and 22.0.2 kernel. From that point, any update to kernel or pkgs to 4.4 (34.x.x to 42.x.x) i get the same issue. The call trace (taken from 1419 id. at bug tracker and re-pasted here) is almost allways the same, and it happends normally when lot of i/o work is performed on an USB external disk, locally or via NFS/exported.

I know usb external disks are used with scsi emulation from the point of view of kernel and they are not a really good approach for massive data storing (rather using scsi units mainly/directly) but i have almost a TB on that disks... By the way i use the workaround of not writing concurrently to that disk for a long time or for long chunks... heh, no more clues unless i rescue the old 4.3 and 22.0.2 raw hd/image for that old host serving as NAS. Don't know if all of this will be helping, anyway... Good luck! Jose.

Keyboard Fails at Login Prompt

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I just setup an old box with CentOS 4 and I'm having a very strange problem. The keyboard is functional throughout the startup process of the machine. I get the login prompt and I get just enough time to type in "root" and hit the enter button before the keyboard fails. I've tried a different keyboard but still the same problem. After a few repeated trials I've found that the keyboard will stop functioning after about 5 seconds from when the login prompt appears on the screen. Does anyone have any ideas on this problem?

From the sound of it, your machine has plenty of power, and you could increase this number. That may or may not help, because it also sounds like the company pulling your content is not doing so in a very polite way and is using a client that opens many, many more connections than an average browser would. I would talk to them about this, personally. robert

Web site development and security

Hello all, I'm looking at building a website and extranet on my CentOS server for my home business. I use PHP for my intranet but I hear PHP is a big security sieve. Can anybody recommend good books on website security and development? Which procedural language should I use to do this? I apologize and realize this may not be the right site for this but it seems there are already a lot of website security and development experts on this list. Thanks in advance, Michael

firewall dropping legitimate packets
by Aleksandar Milivojevic 22 Oct '06

22 Oct '06

I'm experiencing strange problem with my CentOS 4.4 based firewall. In short, it seems to drop packets during larger downloads (several MB in size and larger). Most of the time, the connection itself doesn't break, it is just halted for about a minute or so and that continues. Rather annoying. The problem seems to exist only when downloading content from particular servers. The first rule in my firewall configuration accepts all packets in ESTABLISHED state: -A FORWARD -m state --state ESTABLISHED -j ACCEPT This is basically the only relevant rule. I also have this rule to log dropped packets at the end of FORWARD chain: -A FORWARD -j LOG --log-prefix "FORWARD " Every time the download stalls, I see bunch of packets belonging to that download logged as dropped. If I set /proc/sys/net/ipv4/netfilter/ip_conntrack_tcp_be_liberal to 1, it seems to solve the problem. Being liberal on firewall machine usually is not a good thing, so I'm not particularly happy with this solution. Googling around I found this posting on Netfilter-devel list: http://www.opensubscriber.com/message/netfilter-devel@lists.netfilter.org/2… The replies suggest that the problem is known, and that it was solved in "recent" versions of kernel (recent in this context is around September 2005). Looking at the changelog for kernel package, I don't see any mention of this fix being backported to CentOS/RHEL 2.6.9 kernel. Or maybe I was searching wrong keywords. Anyhow, the main questions are, am I the only one (still) seeing this problem? Does anybody remembers having similar problems, or does anybody knows if above mentioned fix was ever backported into CentOS/RHEL 2.6.9 kernel?

CentOS 3 - I/O performance with Promise HW RAID
by Bart Schaefer 21 Oct '06

21 Oct '06

(Suggestions for other forums in which to post this question are welcome.) We have CentOS 3.6 x86_64 running on a server with dual 2.2GHz Opterons and a Promise UltraTrak RM8000 connected via an Adaptec SCSI card. We are seeing what seems to be gradual I/O performance degradation over time; it seems to be OK for up to about 90 days, but not long after that both CPUs end up continuously spending 50-99% of their time in "iowait" state when reading/writing the RAID device, and processes begin to be stuck for minutes at a time in disk wait state, until finally the server becomes unusable. A simple reboot, even with a forced fsck, does NOT clear this up, but a full shutdown followed by power cycling the RAID device and then rebooting, seems to return things to normal. After doing some research when this most recently happened, we have used elvtune to lower the read and write latency on /dev/sda4 (which is the primary filesystem on the RAID) to 128 and 256 respectively. However, we don't yet know whether this will make any difference, as it has only been 48 hours since the power cycle and it usually takes months for the problem to become noticable. I'd like to get out ahead of it this time if I can, so that we either know when to schedule a power cycle or have some confidence that we won't need to. Any information would be appreciated. (Below this point is just hardware data in case it is helpful.)

CentOS 3.8 Kernel Update with NVIDIA Video Card
by Corwin Burgess 21 Oct '06

21 Oct '06

I need some advice. I updated the kernel but when I restarted my computer I got the following error message: -- I cannot start the X server (your graphical interface). It is likely that it is not set up correctly. ... Failed to load the NVIDIA kernel module! -- I've started my computer using the old kernel. I found out that there's a new nvidia driver so I will also update it. I've downloaded this driver. I can think of two ways to solve this problem but I'd rather have some expert advice. What's the best way to boot with the new kernel, install the nvidia driver and of course update the NVIDIA kernel module? Thanks in advance, Corwin Burgess

centos and apache DOS question
by Tom Diehl 21 Oct '06

21 Oct '06

Hi, I have a centos 4.4 box running Apache serving up web pages. One of my customers has a marketing firm that once a week pulls all of the content so that they can do their thing. When they do this the box stops serving web pages. The load goes to 0.0 and top shows almost no memory free. The box does not swap nor do I get OOM to kick in. Normally the box has about 20-30 httpd processes running but when they are pulling the whole web site I see about 255 httpd processes. If I kill the httpd processes then top shows the load immediately spiking to over 30 and then coming back down to normal. The box is a 3.2 gig P4 with 2 gigs of memory in it. Normally top shows it has 300-400 megs free, with about 300 megs in buffers. I can have the marketing company throttle their downloading of the web site but I think that is the wrong answer. I would like to fix the real cause of the problem. Does anyone know what is going on here or how to troubleshoot this? Is there some kind of tuning I am supposed to be doing to prevent this kind of thing? Do I need more memory? Any help would be appreciated including pointers to docs on this type of thing. So far I have been unsuccessful in finding the correct google incantation to help explain this. Regards, -- Tom Diehl tdiehl(a)rogueind.com Spamtrap address mtd123(a)rogueind.com

file size limit in apache 2.0 on centos 4
by Tony Schreiner 21 Oct '06

21 Oct '06

I think I am encountering a download file size limit on centos 4 with httpd-2.0.52 The file in question is 5.2G in size, it does not show up in a browser directory listing, and I'm getting the error in the http error_log value too large for defined data type: access can someone confirm that there is a 4GB limit (or other) in the standard apache 2.0 on CentOS 4?

Apache is simply not compiled with large file support on CentOS systems. To change this would mean to break binary compatibility, so it is not likely to change until RHEL5 is released.

RE: [CentOS] RE: OT: Problems with Pound Signs and Apache
by Bisbal, Prentice 20 Oct '06

20 Oct '06

Are you sure ALL the files are 100% the same, including executables and libraries? I would do an md5sum of EVERY file that might be even remotely related to the behavior of Apache, Horde and anything else and then compare the MD5sums of all the files on the two different systems. If that doesn't turn up anything, then do rpm -qa and make sure all the packages are at the same version. The problem can still be in a library used by Horde or apache that's further down the stack (we all know what problems changing libc can cause, don't we? ) If THAT doesn't turn up anything, do rpm -Va to verify all the packages on the two systems. -- Prentice -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Andy Wright Sent: Friday, October 20, 2006 9:44 AM To: CentOS mailing list Subject: Re: [CentOS] RE: OT: Problems with Pound Signs and Apache Rex Dieter wrote: > We had similar problems, and our best solution was to remove the > "AddDefaultCharset" config option altogether.

The strange thing is that both Apaches are configured the same so I would expect the same problem with both. This not being the case, I'm thinking the problem is not with Apache but with Horde or elsewhere. However Horde was copied from one server to another (it's actually the original install that's giving the problem so that rules out an error when copying across).

OT: Problems with Pound Signs and Apache
by Andy Wright 20 Oct '06

20 Oct '06

Hi list, I have 2 Centos 4 servers running the Horde system, apparently identical in configuration, but they are behaving differently... On one, when emails containing a Pound Sign (£) are displayed it shows as Â£ (not sure if this will come through right, but it's a capital A with a 'hat' accent over it followed by the pound sign). On the other, the Pound sign displays correctly. I have copied the httpd.conf files over between servers and this has no effect. Looking at the page source both are en-gb and UTF8. It looks like the problem is not with Apache as the config files are identical. Both servers are running the same version of Apache, and for that matter the same version of everything else, and all updates are applied. Would anyone have any ideas where to start looking to track down this discrepancy? Thanks! Andy.

HP Surestore 12000e and multi-LUN
by Paul M. Wright, jr. 20 Oct '06

20 Oct '06

I am running CentOS 4.4 and trying to bring up my tape library. When I do cat /proc/scsi/scsi, it shows only the drive and not the changer although both are shown when the Adaptec card initializes. I recall in the distant past that I had to do "something" to get the kernel to properly scan the SCSI bus for the additional LUN but I cannot for the life of me recall what that was. It would have also been a much earlier kernel. Can anyone here help me out? Regards, paul

Proper partition/LVM growth after RAID migration
by Christian Wahlgren 20 Oct '06

20 Oct '06

Hi This topic is perhaps not for this list, but it I'm running on a CentOS 4.4 and it seems that a lot of people here uses 3Ware and RAID volumes. I did a RAID migration on a 3Ware 9590SE-12, so that an exported disk grew from 700GB to 1400GB. The exported disk is managed by LVM. The problem now is that I don't really know what to do now to let LVM and my locigal volume to make use of this new disk size, and probably future disk size growth. I initially imagined that I could let the physical partition grow and then the LVM PV, the LV and the FS (ext3) to grow to fill up the new exported disk size. Then I realized that this is not how LVM is designed - you add PVs and let the LV and FS to grow. But, what if the underlying exported disk from a RAID card is growing as you add disks to it's RAID volume? Should you create new physical partitions on the exported disk, and specifically, extended partitions, since you might in the future add more than 4 partitions? Secondly, it seems there is a problem after this migration: The graphical LVM shows that I have an "Unpartitioned space" on the exported disk, but I can't click on "Initialize entry" button. The property window on the right says: "Not initializable: Partition manually". parted shows only one partition: [root@acrux ~]# parted /dev/sdb print Disk geometry for /dev/sdb: 0.000-1430490.000 megabytes Disk label type: msdos Minor Start End Type Filesystem Flags 1 0.000 715245.000 primary lvm fdisk in expert mode (x) shows that partition 2-4 fields are all zeros. Should I now make a lvm partition in an extended partition in parted, and then hopefully, the graphical LVM will be able to add the new physical partition to my logical volume, and then resize my fs (ext3)? Thanks in advance for any input on this, Christian

HP (compaq) RAID - How to get alerts?
by Daryl 20 Oct '06

20 Oct '06

Hi All, Background: I have HP RAID setups (Smart Array 5, shows up as /dev/cciss/c0d0) on my DL380s, and they run great with CentOS. I have had a drive failure (HDD lights up amber), so I pulled the HDD, replaced it and the RAID controller rebuilt the array in a jiffy - no probs. My question: I cant find anything in the logs to alert me that a drive failed - this makes sense since the RAID is hardware, so i presume i need some management software however i cant find anything on HP or Compaq's sites to tell me what software i need to be running. I imaging it is something like cpq_alert or such. | Does anyone on the list run HP or Compaq hotswapable kit? How do you get alerted to failures? Thanks, MrKiwi

I am having some issues (e.g. System lock ups) with my ATI 9250 Video card. I am thinging about replacing it with either a Nvidia FX5200, FX5500, or a FX5600 card. Is anyone using one of these cards on Centos 4.1 with the stock (XORG) nv driver?

The problem using things like dyndns and forwarding to a dynamic ip is that there is a possibility that when your ip has changed mail would be attempted to be delivered to the next user that gets your previous ip.

Use your isp's smtp server to relay everything. I am using it on this server to send you this. There is even a way to set it up with smtpauth Also I don't have a problem with a dynamic ip since I have a client installed there is a couple of places that seem to do a better job then others.

I have been using the nvidia driver although I do not need the 3D acceleration, just because it was available. However, a few of days ago I came across this: http://kerneltrap.org/node/7228 http://download2.rapid7.com/r7-0025/ what does this list think about this matter? I have now reverted to the standard xorg nv driver --------------------------------------- You have to weigh the risk of th exploit with the benefits of using the software. What are the odds that someone is really going to target your computer out of the millions connected to the Internet? What value does using this driver provide? Is that value worth the risk? For me, without using this driver, I can't provide the hardware-accelerated 3D stereo my users need to do their work. Since my systems are behind a firewall with NAT, I think the risk of falling victim to this exploit is pretty low (yes, I know firewalls are hardly a panacea). In my case, the benefits clearly outweigh the risks. As to why NVidia hasn't fixed this problem, that's a discussion for another mailing list.

Changing kernel params in CentOS 4.2
by Debbie Tropiano 19 Oct '06

19 Oct '06

Hello - One of my users would like a kernel parameter changed. We're running CentOS 4.2 so I'm not sure if we need to upgrade the kernel for this change or not. He's seen that in the 2.6.11.12 kernel "PIPE_SIZE is defined in include/linux/pipe_fs_i.h and takes on the value of PAGE_SIZE" He wants PIPE_SIZE to be increased to 8*PAGE_SIZE. Can this be changed in the 2.6.9 kernel? If so, where would this be changed? If not, what kernel would be suggested for an upgrade (we have some experience with FC3 & the 2.6.11 kernel already)? Last, in your opinion does changing the kernel rev greatly change the name of what you're running? If we go to say the 2.6.16 kernel on our CentOS 4.2 system, is it still valid to call it CentOS 4.2?

Alfred, You can use xvidtune or gtf to generate modelines. Both should be included with your distribution.

If you're going to do that, you definitely want to tweak the settings for Full-Scene Anti-Aliasing (FSAA). How to do that is documented somewhere in the NVidia-supplied documentation. Using Unreal Tournament, as a test case, I set FSAA to the most intensive algorithms, set the resolution to the highest that UT supported, and still had ridiculously high frame rates and ultra-smooth animation! -- Prentice -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of chrism(a)imntv.com Sent: Wednesday, October 18, 2006 1:38 PM To: CentOS mailing list Subject: Re: [CentOS] Switch to Nvidia from ATI Bisbal, Prentice wrote: > We use NVidia cards to do 3D hardware stereo graphics to view > molecules in 3D.

I only updated to the nvidia-supplied driver on a couple of machines because "it was there" not because the stock driver was slow or broken.

APIC error on CPU0: 60(60)

I have a lot of this errors in my Centos stock 4.3 version in an Intel D945gnt motherboard with a Pentium D (dual core) If I disable apic in the grub.conf (apic=off) will I get a performance hit?

I/O resource -- not free --- IRDA problems?
by Robert Moskowitz 18 Oct '06

18 Oct '06

I get a message while booting of: ide2: I/O resource 0x3EE-0x3EE not free. ide2: ports already in use, skipping probe Googling for this, I find it is relatively common, and on different laptops. I thought it might be my internal SD reader causing the problems, but these other notebooks do not have such devices. Then I found: http://www.cl.cam.ac.uk/~pb22/I8600/ and: " IrDA - works except on COM3 / ttyS2 It appears that *ttyS2* (the FC2 default) does not work as the IrDA - on boot it reports `*ttyS2 at I/O 0x3e8 (irq = 0) is a 16550A*' and `*ide2: I/O resource 0x3EE-0x3EE not free.*', `*ide2: ports already in use, skipping probe*'. As such, during *POST* press *F2* and *Alt-P* 3 times and set the IrDA to *COM2* or *COM4* (which select *IRQ 3* with *I/O 0x2f8* or *0x2e8* on *ttyS1* or *ttyS3* - ra3 is the latter). Edit */etc/pcmcia/config.opts* to `*exclude irq 3*' (so that the IRQ is free) and */etc/sysconfig/irda* to set `*DEVICE=/dev/ttyS3*' (or *1*), and run `*chkconfig irda on*' so that it starts on reboot (or `*/etc/rc.d/init.d/irda start*' or `*irattach /dev/ttyS3 -s*'). It should load *ircomm_sir*, *sir_dev*, *irnet*, *ppp_generic*, *slhc*, *ircomm_tty*, *ircomm*, *irda*, *irtty_sir* and *crc_ccitt*, and */var/log/messages* should have" Now I have already put ttyS2 on irq3 (from dmseg): ttyS2 at I/O 0x3e8 (irq = 3) is a 16550A How do I test the IRDA?

CentOS 2.1 on i586
by Aleksandar Milivojevic 18 Oct '06

18 Oct '06

I've just attempted to reinstall my ancient laptop that has Pentium MMX processor. Since it is ancient, I've decided to go with CentOS 2.1. Got stuck, installer claims I need at least i686. Hmmm... I know that 3.8 and 4.4 work without a glitch on i586, so this came as surprise. I even thing original RHEL2.1 might had support for i586 too (but I might be wrong). Anyhow, what happened with i586 in CentOS 2.1?

make 3.79.1 assertion failed error
by Dag Wieers 17 Oct '06

17 Oct '06

Hi, Sorry for cross-posting but I need to tap into my most helpful mailinglists for this problem. I have had assertion failed errors from make before and never understood what they were or where they came from. But now that I have them consistently for ffmpeg and mplayer on everything smaller than FC2, which prevents me from updating both mplayer and ffmpeg (and I know lots of other applications have the same issue). The exact error is: make: expand.c:489: allocated_variable_append: Assertion `current_variable_set_list->next != 0' failed. By coincidence (called Google) I found this page: http://valgrind.org/docs/manual/faq.html#faq.make_dies and it made the relation with make 3.79.1 pretty clear. (fc1, el3, rh9, rh7 and el2 all use make 3.79.1) I was wondering if anyone knows of a better solution than explained in the valgrind FAQ, or better than upgrading make. Once upon a time mplayer built without this assertion, other applications as well. So is this caused by a more recent configure/autotools used by the developers ? Some way to prevent this ? Anyone ? :) Kind regards, -- dag wieers, dag(a)wieers.com, http://dag.wieers.com/ -- [all I want is a warm bed and a kind word and unlimited power]

yum repository and createrepo
by Ken Leyba 17 Oct '06

17 Oct '06

I've setup a local yum repository for about 25 workstations and I'm using rsync from a local mirror. Do I need to create my own XML headers, i.e. the 'repodata' directory, or since I'm syncing the whole updates directory can I use the 'repodata' directory from the mirror? I also have a question on using createrepo. The directory layout is: ~/updates/ ~/updates/headers/ ~/updates/repodata/ ~/updates/RPMS/ If I do the following in the 'updates' directory: # createrepo -v ./RPMS The 'repodata' diretcory is created under the 'RPMS' directory and not the current 'updates' directory. How can I have the 'repodata' directory created/updated in the correct directory under 'updates'? Right now I'm manually moving the directory. I would probably need to do this in my daily cron job.

Here is where things currently stand. I have taken the two arrays and swapped them between the two systems. The Seagates are still slower. However, since the OS is installed on these arrays, I don't know if this is due to the drives or some OS setting. I have also taken one spare drive of each type and tested each one as a single-drive unit in both systems. These tests all give similar numbers and show that the Seagate drives are marginally faster than the Maxtors. -- Bowie

hey friends, I am running Mysql server version: 4.1.20 on Centos 4.0. The problem I am facing is that I am not able to access the databases if I login through anyother user for example test1 mysql -u test1 -p Enter password: ERROR 1045 (28000): Access denied for user 'test1'@'localhost' (using password: YES) I have granted all the privileges for user test1 on databases test & test1 set password for test1@'172.23.96.0/255.255.252.0'=password('test'); show grants for test1@'172.23.96.0/255.255.252.0'; +-----------------------------------------------------------------------------------------------------+ | Grants for test1(a)172.23.96.0/255.255.252.0 | +-----------------------------------------------------------------------------------------------------+ | GRANT USAGE ON *.* TO 'test1'@'172.23.96.0/255.255.252.0' IDENTIFIED BY PASSWORD '378b243e220ca493' | | GRANT ALL PRIVILEGES ON `test`.* TO 'test1'@'172.23.96.0/255.255.252.0' | | GRANT ALL PRIVILEGES ON `test1`.* TO 'test1'@'172.23.96.0/255.255.252.0' | | mysql | | test | | test1 | I want to give user test1 all the privileges on databases test and test1 and the user test1 can access mysql from any pc within the LAN that is why I have created user test1@'172.23.96.0/255.255.252.0' I can access all the databases through user root but not through user test1. SElinux and IPtables are off. I have restarted mysql few times and even restarted my system 2 times but still the problem is persisting. Please let me know if you need any further inputs.

USB multi-card reader working, finally took the time
by Robert Moskowitz 17 Oct '06

17 Oct '06

A thread on multi-cards 2 months ago, gave me a hint on how to get usb multi-card readers working: Quoting "J.J. Garcia" <stigmatedbrain(a)gmail.com>: "Have you tried putting it into /etc/modprobe.conf (options scsi_mod max_luns=32) and rebuilding initrd image after that? That's the way I was doing it so far, and it always worked for me. " So I then had to learn how to rebuild initrd image. Turns out that is mkinitrd (duh :-[ ). So I added to my /etc/modprobe.conf: options scsi_mod max_luns=8 Then: mkinitrd -v --image-version .... edited /boot/grub/grub.conf to use this new initrd, and now my MP3 players with internal and external SD cards are working properly. I am ASSuMing that once modprobe.conf is altered, as I get new kernels, the change will carry forward, and I will not have to do my own mkinitrd? I base this on my recent update to 42.0.3 and a new initrd file.

CUPS Problem

The Highlights: -CentOS 4.4 & CUPS -HPLIP Installed -Running as server, no GUI. -Can print from command-line no problem. -Printing from Windows XP via Samba puts job in the correct queue, job is processed but not parsed or rendered. The job is removed from the queue, but never prints. (I've RTFM and google'd it, no avail...) Help?? When printing from commandline (eg. cat file | lpr), this is the result I got.

There may be minor differences, but I would not expect this much difference. Actually, further testing has shown that the write performance on the second machine varies anywhere from 20MB/Sec to 54MB/Sec depending on when I test it. Unfortunately, it appears random from my point of view. I'm still running tests to try to find a cause or at least a related symptom. The First system has Maxtor 7V250F0 drives (250GB). The second system has Seagate ST3500641AS drives (320GB). They are both 7200RPM SATA II drives with 16MB cache and NCQ support. -- Bowie

3Ware 9550SX-4LP Performance
by Kirk Bocek 16 Oct '06

16 Oct '06

I know there are a few 3Ware fans here and I was hoping to find some help. I just built a new server using a 3Ware 9550SX-4LP with four disks in raid 5. The array is fully initialized but I'm not getting the write performance I was hoping for -- only 40 to 45MB/Sec. 3Ware's site advertises 300MB/Sec writes using 8 disks on the PCI Express version of this card (the 9580 I think.) I'm guessing 4x PCI Express has more bandwidth but 133Mhz 64-bit PCI-X is no slouch. The only two things I need to change are to put the disks in 3GB/Sec SATA mode (they're in 1.5GB/Sec mode right now) and to enable memory interleaving on the motherboard (I only have two sticks of memory, this M/B needs 4 for interleaving.) But I don't think these things should drop me down to the write performance of a single IDE disk. Does anyone have any suggestions on improving write performance? The Details (I know the devil is in here somewhere): Supermicro X7DVL-E Motherboard Dual Xeon 5130 (2 Ghz) 2GB RAM 3Ware 9550SX-4LP in a 133Mhz 64-bit slot. 4x Seagate ST3400620AS 400GB SATA Drives NCQ Enabled but currently in 1.5GB/Sec mode CentOS 4.4, Kernel 2.6.9-42.0.2.ELsmp Stock Kernel 3Ware Driver 2.26.04.010 Bonnie++ 1.03a 50GB Benchmark run four times on an ext3 filesystem: ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP Beryl 50G:64k 44572 77 53084 14 40624 7 47790 72 162504 12 96.5 0 Beryl 50G:64k 45960 79 53068 14 39972 7 47701 73 162510 12 96.8 0 Beryl 50G:64k 36846 64 37579 10 36785 6 48090 72 162609 12 96.9 0 Beryl 50G:64k 45205 77 53621 15 40757 7 48325 73 162331 12 96.4 0 ------Sequential Create------ --------Random Create-------- -Create-- --Read--- -Delete-- -Create-- --Read--- -Delete-- files:max:min /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP Beryl 16 3928 99 +++++ +++ +++++ +++ 3961 98 +++++ +++ 12442 99 Beryl 16 3929 98 +++++ +++ +++++ +++ 3957 99 +++++ +++ 12373 100 Beryl 16 3718 94 +++++ +++ +++++ +++ 3389 84 +++++ +++ 12307 99 Beryl 16 3920 98 +++++ +++ +++++ +++ 3969 99 +++++ +++ 12421 99

I can try that, but when I tested on the first server, I found that disabling NCQ increased the read performance by 10M/s and decreased the write performance by 10M/s. Maybe I'll get different results from the Seagate drives. -- Bowie

Uneven CPU speed with CentOS 4.4 on a Mac Pro
by Michael Lampe 16 Oct '06

16 Oct '06

Hi list, I've recently managed to install CentOS 4.4 on an Apple Mac Pro. Functionality-wise everything works great, but when trying to benchmark the system, I don't get stable runtimes, they differ by more than 30%. For example a benchmark run with our PDE solving code takes between 500 and 800 s on the completely unloaded machine. Suspicious kernel output (complete output attached): PCI: Probing PCI hardware (bus 00) PCI: 0000:00:03.0: class 600 doesn't match header type 01. Ignoring class. PCI: 0000:00:05.0: class 600 doesn't match header type 01. Ignoring class. PCI: 0000:00:06.0: class 600 doesn't match header type 01. Ignoring class. PCI: 0000:00:07.0: class 600 doesn't match header type 01. Ignoring class. and quite a bunch of APIC error on CPUx: 60(60). This is probably due to Apple's not quite perfect BIOS emulation code. According to /proc/cpuinfo the CPUs don't support any power managment, cpuspeed isn't running or even configured, and they are always shown as 2.66 GHz, which is correct.

tg3: eth0: No interrupt was generated using MSI, switching to INTx mode.
by Andreas Micklei 16 Oct '06

16 Oct '06

Hi, I just installed CentOS 4.4 x86_64 on our new 2 x Dual Core Opteron Server. First the system was unstable, but I after turning of Power-now it runs stable (anyone else experienced this?). However the following line in dmesg puzzles me: tg3: eth0: No interrupt was generated using MSI, switching to INTx mode. Please report this failure to the PCI maintainer and include system chipset information. Has someone else experienced this? What does it mean and who am I supposed to contact? Sorry if this is a stupid question, but a simple pointer would be appreciated. Apart from this message the system runs fine. Hardware Information: Server: Supermicro 816S-R700 Motherboard: Supermicro H8DSP-8 Chipset: ServerWorks HT2000 / HT1000 Processors: 2 x Opteron Dualcore 2.2 GHz RAM: 4 GB Ethernet is of course on the mainboard. I have already upgraded the tg3 driver with the latest version from Broadcom, but the line in dmesg still appears. regards, Andreas Micklei

Latest kernel fixes AMD cool 'n quiet
by Centos Admin 16 Oct '06

16 Oct '06

Just thought I'd follow up on my post from around august.... it seems that the latest kernel has indeed fixed the cool 'n quiet issues with my Athlon X2 3800. basically the following messages were appearing; powernow-k8: ignoring illegal change in lo freq table-2 to 0x2 powernow-k8: transition frequency failed and both cores were going at full 2.0ghz speed. Now with 2.6.9-42.0.3.ELsmp the errors have disappeared and both cores are running at 1ghz when the system is idle. I'm very surprised as I checked the changelog (rpm -q --changelog) and there was no specific mention of any fix that I could find. I had actually toyed with the idea of running another distro on the server as it lives in my garage which, obviously, has no Aircon and the summers here in Brisbane get pretty hot.

'Political' Questions on CentOS please
by Tom Brown 16 Oct '06

16 Oct '06

Hi I have used CentOS personally for 'ages' but i have some questions that i need answering from the wider audience. These are for management as i am proposing RHEL for our QA and Prd infrastructure and CentOS for dev. I would go CentOS for all areas but we need 'support' on our prd systems. Can anyone tell me roughly how many cpu's are running centos? How widespread is it, does anyone really know? How many developers are helping with CentOS? When did CentOS 'start' and how long will it be around for? I am trying to get an accurate answer to fend off the 'well it could disappear at any minute' argument. thanks guys

YUM needs older version

Sorry to bring this topic up again, but I am confused as to why yum needs an older version and how to resolve the problem. I get this error from yum: Error: Missing Dependency: httpd = 2.0.52-22.ent.centos4 is needed by package httpd-manual Error: Missing Dependency: libgcj = 3.4.5 is needed by package libgcj-devel Since most of this is outside my skill set, I am not sure if "yum resolvedep httpd" is the correct way to determine what is present, nevertheless, I got httpd-2.0.52-28.ent.centos4.i386 and libgcj-3.4.6-3.i386 for libgcj. That appears to be telling me that I have newer versions of both currently installed. Is that try? How can I resolve the problem?

smbmount: mount() syscall gone bad ?
by Rodrigo Barbosa 14 Oct '06

14 Oct '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have seen a weird problem in one of my clients. The reported that when issuing a smbmount command (both client and server are CentOS 4.4), it would take up to 30 second for the mount to complete. To make a long history short, by using strace and the source, I noticed smbmnt is first calling mount() using ascii options for *data. Then that would timeout, and it would try again using a struct, finally working. Looking at the source code, it will first try ascii if kernel >= 2.4, and fallback to struct if it doesn't work. So changing smbmnt.c to always using the struct first solved my problem. I also noticed that debian will always go first for the struct aproach. Anyone seen this before ? - -- Rodrigo Barbosa "Quid quid Latine dictum sit, altum viditur" "Be excellent to each other ..." - Bill & Ted (Wyld Stallyns) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) iD8DBQFFKmyrpdyWzQ5b5ckRAnq4AJ9Z2ZCe3denIoWFK5ePWF7INHqMjwCgs+9c bNCRI/9fJ9B1Cg2gGD4hPHM= =Qa4R -----END PGP SIGNATURE-----

automatic shutdown of UPS (and RAID1)
by Ben 14 Oct '06

14 Oct '06

I have an MGE UPS Pulsar Ellipse 600 USBS that I'm setting up with CentOS 4.4 I tried for some time to get it working with USB, but failed and I have had much more success using the serial port. I have managed to complete the whole install procedure (shown here: http://www.networkupstools.org/doc/2.0.1/INSTALL.html )but I'm lost when it comes to implementing the shutdown script. I'm also using Software RAID1 for all partions (/, /boot, swap, and two others). I've never edited shutdown scripts before and after a few days of Googling and manual reading I'm still not sure what to do. Is it as simple as just putting the script in a file in the rc0.d directory? I'm not sure what the file should be named so the script is run at the right time, and I don't know how to ensure the software RAID1 is ready to be powered off. Feel free to tell me to RTFM, just let me know which FM I should be looking at. :-) Here's the step I'm stuck on: 11. Edit your shutdown scripts: add upsdrvctl shutdown You should configure your system to power down the UPS after the filesystems are remounted read-only. Have it look for the presence of the POWERDOWNFLAG (from upsmon.conf), using this as an example: if (test -f /etc/killpower) then echo "Killing the power, bye!" /usr/local/ups/bin/upsdrvctl shutdown sleep 120 # uh oh... the UPS power-off failed # you probably want to reboot here so you don't get stuck! # *** see the section on power races in shutdown.txt! *** fi Be careful: that upsdrvctl command will probably power off your machine. Don't use it unless your system is ready to be halted by force. If you run RAID, be sure the arrays are ready to lose power. Your kernel's power-off routines may not execute. Make sure that the filesystem(s) holding your UPS drivers and configuration details are still mounted when that part of the script is run. You need upsdrvctl, ups.conf, and any drivers for the hardware on your system. --- Ben

IP addressing migration
by Ivan Arteaga 14 Oct '06

14 Oct '06

Hi, I am changing the IP addressing in my centOS server which works as mail server. The question I have is, if I define the new IP addresses (sub-interfaces) on the server, can I work with both ranges at the same time despite I have only one default gateway configured? (on the old range) Or may I have two default gateways in centOS? --Ivan. -------------------------------------------------- Ivan Arteaga Grupo Regency Senior Network Consultant Phone: +507 205-8307 Email: <mailto:iarteaga@plazareg.com> iarteaga(a)plazareg.com <mailto:ivan.arteaga@sisa.com> ivan.arteaga(a)sisa.com "Look both ways before crossing the Net"

migrating servers (advice)
by Ajay Sharma 13 Oct '06

13 Oct '06

Hi, I'm about to copy the contents of one server onto another. The "plan" that I've come up with is: 1) boot the new server with a live disc, partition accordingly 2) a big tar-over-ssh for the /boot, and root partitions (that's all there is) 3) adjust the fstab so that it'll find the new scsi partitions vs. the old ATA ones. 3) then chroot into the new system and run grub to initialize the bootloader. I'm switching a server from a single HD to a SCSI mirror on our new machine. So it has a different partition setup and I don't want to mess with resizing. Does that sound about right to get the machine booted? I'm sure there will be some other minor things but I can sort that out once I get the data over and the machine booted. --Ajay -- Satyajot (Ajay) Sharma REVShare System Administrator

Safely updating to 4.4 via yum (chicken)
by techlist 13 Oct '06

13 Oct '06

Hi guys: I saw the pelthora of threads where people had trouble moving to 4.4. So I'm chicken now and I was trying to wait for the dust to settle, I suppose it has and its been long enough I'm nervous about not upgrading. I need to do a a production server that is located in a data center far away so even more than normal I want a smooth upgrade. Can someone tell the what the concensous was on the best way to do the upgrade and avoid problems. From my notes I got: yum upgrade python-sqlite yum upgrade sqllite yum upgrade yum yum clean all yum update But at least one guy said his box was still hosed with duplicates and a broken bind after that. What's the method to upgrade 4.3-> 4.4 with the highest change of sucess? Thanks very much for the help. Scott

Write performance with 3ware 9550
by Bowie Bailey 13 Oct '06

13 Oct '06

I have two identical servers. The only difference is that the first one has Maxtor 250G drives and the second one has Seagate 320G drives. OS: CentOS-4.4 (fully patched) CPU: dual Opteron 280 Memory: 16GB Raid card: 3ware 9550Sx-8LP Raid volume: 4-disk Raid 5 with NCQ and Write Cache enabled On the first server I have decent performance. Nothing spectacular, but good enough. The second one has about 1/3 the write speed. I can't find any difference between the systems. Both of them have the same stripe size, both have ext3 filesystems, both have write caching and NCQ turned on. I have already increased the read ahead setting to 16384 on both servers. I ran the tests like this: # sync; bonnie++ -d /iotest -s 50g -n 0 -b -f (I have removed some extra information from the reports for brevity) And here are the results for the two servers: ------Output------- --Input-- --Block-- -Rewrite- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP /sec %CP First 50G 62893 25 46763 12 160672 19 120.6 1 Second 50G 18835 7 44025 12 194719 24 122.8 1 As you can see, the write performance of the second server is terrible. Anyone have any suggestions of what I can look for? I keep thinking there must be something I tweaked on the first server that I forgot about for the second one, but so far I haven't been able to find it. Any suggestions appreciated! -- Bowie

Apache DirectoryIndex
by Kirk Bocek 13 Oct '06

I'd like to change the DirectoryIndex document for just the DocumentRoot, leaving the default DirectoryIndex setting for all other directories. However, when I set DirectoryIndex in the <Directory "/var/www/html"> section of /etc/httpd/conf/httpd.conf it seems to set it for *all* directories. DirectoryIndex doesn't seem to be allowed in .htaccess either. Does anyone know how to set this? Thanks, Kirk Bocek

Cluster Quorum Question/Problem
by Brandon Hall 13 Oct '06

13 Oct '06

Greetings all, I am in need of professional insight. I have a 2 node cluster running CentOS, mysql, apache, etc. I have on each system a fiber HBA connected to a fiber SAN. Each system shows the devices sdb and sdc for each of the connections on the HBA. I have sdc1 mounted on both machines as /quorum. When I right to the /quorum from one of the nodes, the file doesn't show up on the other. However, if I unmount and remount the device on the system that can't see the new file, the file shows up, but is broken/red and cannot be accessed by the node that couldn't see it in the first place. This works in both directions. Do I have things set up wrong? I'm so confused..... If they are sharing the same virtual drive on the same device in the same place, how can it not be the same on both systems??? Any help is appreciated! _________________________________________________________________ SearchYour way, your world, right now! http://imagine-windowslive.com/minisites/searchlaunch/?locale=en-us&FORM=WL…

Kirk Bocek wrote: > Responding to several of your posts here. I understand your need for > stability, but can't you set StorSave down and see what it does to > your speed? I could, but I don't see the point. I have one machine with StorSave set at "Protect" which writes at 60MB/Sec. The other identical system which is also set to "Protect" only writes at 20MB/Sec. Therefore, there must be something else at work. As we speak, I have swapped the hard drives in these two systems and I am running another test. This will at least tell me if the problem is based in the hard drives & OS or elsewhere in hardware. > Some of my 95MB/Sec was achieved with some of the suggested ext3 > journal settings.

Both systems currently have it turned off, so I haven't touched it at this point. Once I have determined why the performance is so different between these two machines, I may experiment with that setting to see if it helps. Right now, I am not looking for maximum performance. I am just trying to determine why there is a 3x difference in write performance between two identical machines. -- Bowie

Non-interleaved memory sounds interesting. Where do I change that setting? I don't want to change the StorSave setting. I'm not really looking for maximum performance here, just reasonable. If I can get the same 60 M/s speed that I got from the first server, I'll be happy. The drives are all running at 3.0GB/Sec according to the drive information in 3DM. I have read the entire "Calling All FS Fanatics" thread as it passed through the list. It was quite interesting, but the main things I got from it are: - Increase the read ahead settings - XFS, JFS, and ReiserFS are faster, but less fault-tolerant, than ext3 I have already changed the read ahead on both the physical volume and the logical volume. This gives me increased read performance, but has no effect on writes. I am sticking with ext3 since I am much more concerned about stability than performance.

Training Material: Books about linux but targeting Centos installations
by Erick Perez 13 Oct '06

13 Oct '06

Hi, I am about to give a training session in Linux, using Centos 4.4 as a base. I want to give my students (MS windows administrators) printed books about Linux and hopefully Centos based. It is a total of 20 books. I'm also interested in purchasing 20 copies of the DVD of Centos 4.4 x86/x86_64 distro. My initial search at amazon returned no useful results. It can be RHEL 4, Centos 4 or fedora 4 based but I really want them to be Centos if possible, given the fact that I often scracth RHEL intallations in favor of Centos (i know is the same base, but I would like to match the book with the distro). The books have to be focused to Linux administration and installation (like web,ssh.mail.etc). There is no need to cover in-depth programming (perl,bash,etc). Can anyone in the Centos community have some references of these books/DVDs for purchase? Thanks, -- ------------------------------------------------------------ Erick Perez Panama Sistemas Integradores de Telefonia IP y Soluciones Para Centros de Datos Panama, Republica de Panama Cel Panama. +(507) 6694-4780 ------------------------------------------------------------

Turning NCQ off definitely made a big difference > for me. With NCQ off, I get these results: Version 1.03 ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP Second 50G 20853 8 41899 11 192713 23 116.9 1 Write performance increased by 2M/s and read performance decreased by 2M/s. What tweaks have you applied so far? I would expect a 4-drive array to be slower than an 8-drive array, but not this much! -- Bowie
