php53 and pear
by Michael Simpson 05 Apr '11

05 Apr '11

Hi all We require some packages installed through pecl (apc and memcache) which we have done on CentOS 5.5 by installing php 5.2 from testing and also installing php-devel and php-pear to much success! We would like to move to php 5.3 after 5.6 comes out but I note that there is no specific php53-pear package in testing and the php-pear srpm in the 5server directory on ftp rc com seems to be quite old. I also note that there was a php53-pear.spec posted in this list file with (?unsanctioned) mention of the possibility of this going in extras. Is it prudent to install pear using the php go-pear.phar method for php53 and will this then give me access to pecl though with the same downside as using cpan for perl (do not want) or will there be an "official" php53-pear rpm available through centos.org? I'm sorry if this has been answered before but my google-fu seems to be letting me down. regards mike

3.5 kernel panic on boot
by Bruce Ferrell 05 Apr '11

05 Apr '11

Yes, I know 3.5 is old. However in this case it's required for a legacy app. a fresh install get's me: kmod: failed to exec /sbin/modprobe -s -k block-major-104, errno = 2 followed by: VFS: Cannot open root device "cciss/c0d0p2" or 68:02 The system is an HP DL380 G4. any thought on what could cause this? the rescue system is able to mount the disk and grub-install works to re-install grub on the device.

I really have no way to respond to such a thorough misreading of what I have said. I don't even know where to begin. For everything you claim I have said I have in fact said the exact opposite. I have no idea where you get the idea of lumping me in with those throwing a tizzy about the releases not being ready. The only thing I have said is that if we want these weekly threads to stop there needs to be better communication. How that translates in your head as me and everyone else "demanding" all sorts of things, pressuring the project, or wanting premature releases is simply beyond any ability of reasonable thought. // Brian Mathis P.S.

Door not hitting me on my way out
by Nico Kadel-Garcia 05 Apr '11

05 Apr '11

Sorry, folks. I wish our release developers well, and hope that they can open up their processes to allow much needed community involvment. But I've hopped to Scientific Linux and find it much more usable due to their willingness to publish updates even without the entire new release bundled, and the much timelier updates from the upstream vendor. php53 and bind97 are directly available for their verison 5.x release, and their version 6.0 has now taken over my testing environments. This makes EPEL's version of drupal, and various Samba 4 testing accessible, and I don't have to waste my time on backports that will be replaced by a release that is further, and further, and further behind. Perhaps in the future the configuration of the build and patch environments can be opened up, or the patching going on for the package rebundling can be published in just the way people with RHEL would publish their kernel patches, rather than presenting merely the results. But such ideas have been rejected as unnecessary, and even the suggestion was rejected with hostility. I know very well how much work such projects take, and regret that I was unable to assist further. My tweaks and bundles will now be going over to Fedora and Scientific Linux, rather than here or in the developer's list. Nico Kadel-Garcia <nkadel(a)gmail.com>

lvm and kickstart issues deploying CentOS5.5

Hi. I'm currently trying to configure a kickstart script to do auto installs. We split up the partitions so that we have control on the mount security like setting no execute on the tmp portions etc . I keep hitting the same error : "Could not stat /dev/VolGroup00/LogVol_root --- No Such file or directory The device apparently does not exist; did you specify is correctly " Even after doing a manual install to generate the file lvm configuration I'm getting the same results.

interview request for ppl who have Shockwave/.Firefox working
by ken 04 Apr '11

04 Apr '11

For a long time now I've wanted to be able to watch videos. I've done the "try this!" and "try that!" method and it hasn't worked well. So I'm wondering if anyone running CentOS 5.5 has Shockwave on Firefox working. Currently it works for me with short videos-- up to two or three minutes long. However, when Shockwave is enabled, CPU usage jumps to 99%, sometimes even 100%! If I disable it CPU usage goes down to 1 - 5%. (For those who speak load avg, I've seen highs of 6 and 8... as opposed to the no Shockwave-now of 0.14 to 0.45.) So with the CPU already buried just by having Shockwave is enabled, if a video lasts longer than four minutes, gaps in the video's continuity begin to appear, and by ten minutes in the video is locked up altogether. What's everyone else's experience with this? Does anyone have a setup where they can view a 1.5-hour video normally... and maybe even work in their editor alongside it at the same time? If so, would you be open to explaining what hardware and software etc. you've got so that this works so well? Thanks. -- Anything is easy if you know how to do it.

Best way to extend pv partition for LVM
by Kai Schaetzl 04 Apr '11

04 Apr '11

I've replaced disks in a hardware RAID 1 with larger disks and enlarged the array. Now I have to find a way to tell LVM about the extra space. It seems there are two ways: 1. delete partition with fdisk and recreate a larger one. This is obviously a bit tricky if you do not want to lose data, I haven't investigated further yet. 2. create another partition on the disk, pvcreate another pv and then add it to the existing volume group with vgextend 3. a possible third way: increase the partition size. According to Google most if not all disk tools want to resize a file system as well and since there is no file system they will fail. I'm not sure about the status with this for the tools that come with CentOS (fdisk, parted, other?) No. 2 seems to be the easy way. Any objections? One I thought of: What does happen when I use No. 2 and I add new lvs? Can it happen that new lvs get "spanned" over both pvs or can I assure that a pv gets created using only one of the pvs? (I would prefer the latter, it doesn't matter if I use a few MB because of the ineffectiveness of allocation.) Thanks for recommendations. Kai

cobbler installation of CentOS-5.5
by Timothy Murphy 04 Apr '11

04 Apr '11

I'm trying to install CentOS-5.5 on my new HP micro-server, which has no CD drive. I've set up cobbler and cobbler-web on my old server, and can access cobbler-web from my laptop. I have 3 queries about the installation. 1. Is there any advantage is using the 64-bit CentOS rather than 32-bit? 2. The CentOS OS seems to be available in 7 or 8 CDs. (I tried downloading the DVD ISO with ktorrent, but this was a complete failure. It started OK, but then created literally thousands of links to one file, which brought my server down, and left it in a state which was quite hard to clean up.) But how exactly do I "cobbler import" these? I see that for Fedora on my laptop I ran sudo cobbler import --path=/mnt/dvd --name=F14-i386 3. Is there actually a way of converting the 7 or 8 CD ISOs into a DVD ISO? I saw instructions that suggested concatenating them, and then running rsync against a DVD ISO, at <http://lists.centos.org/pipermail/centos/2011-January/104448.html>. I tried the site recommended, but could not access the DVD ISO. In fact, if I could access a DVD ISO, couldn't I download it directly? So what would be the point of this exercise? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

KVM Host Disk Performance
by Chuck Munro 03 Apr '11

03 Apr '11

Hello all, I'm having quite an interesting time getting up to speed with KVM/QEMU and the various ways of creating virtual Guest VMs. But disk I/O performance remains a bit of a question mark for me. I'm looking for suggestions and opinions .... This new machine has tons of disk space, lots of CPU cores and loads of RAM, so those are not issues. I currently have several software RAID-6 md's, each of which is about 700 GBytes. The md's are created as partitionable arrays, and I assign the resulting "raw" disk devices to each CentOS Guest OS, which then partitions the space according to its needs. Unlike using the more common "filesystem-in-a-file" method, the use of partitionable MD devices usually results in wasted disk space, but my aim is to provide the best performance possible with robust RAID. Is there a better-performing way of assigning disk space to Guest VMs? What about 'qcow2'? I understand its copy-on-write offers several advantages, but does it perform better than using partitionable md arrays or does the underlying filesystem overhead get in the way? Perhaps the native overhead of RAID-6 dual parity makes the whole question moot. Would the use of RAID-10 with hot spares be paranoid enough? I'm using 2 TByte drives which inherently have much greater chances of data errors, so I must keep data reliability in mind. I don't want to start a religious war over RAID and Guest VM disk methodology, but I have the luxury of trying various disk configurations until I get a reasonable balance between performance and reliability with these large drives. So many questions ... so much to learn. Lots of Googling around is quite useful but can lead to information overload :-) Cheers, Chuck

repeated local ephemeral to 80
by Michael D. Berger 02 Apr '11

02 Apr '11

On my CentOS box that I use mainly as a web server, I have iptables set to log and reject anything that I don't expect. So lately, I have getting things like this: Mar 29 17:27:20 mbrc20 kernel: IPT-DROP IN= OUT=lo SRC=192.168.9.20 DST=192.168.9.20 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=46910 DF PROTO=TCP SPT=56624 DPT=80 WINDOW=32792 RES=0x00 SYN URGP=0 OPT (0204400C0402080A4A26F7A50000000001030307) UID=0 that on at least one occasion repeated for every few seconds for more than three hours. The ephemeral source port keeps changing in an irregular manner. Any suggestions? Thanks, Mike

Cent OS clustering and Support.
by Kumar, Ranjan 02 Apr '11

02 Apr '11

Hi, We are a Channel product team within LSI and we are trying to add Cent OS 5.5 to our compatibility Matrix. We found out that LSI currently has a relationship with CentOS for another project on the Internal Storage division but not with the OS Certification team. We require some information on CentOS which will help us plan the deliverables. And considering the timelines we need to deliver at it will be great if someone from CentOS can help us out in this regard. If anybody else also can answer these in the mailing list, we would be grateful. The questions that we have are as follows:- 1) Cluster Support : * Does CentOS 5.5 provides native cluster support ? * Is there any cluster suite available for CentOS 5.5 ? * Can we use the cluster suite in CentOS 4 for 5.5. 2) Does CentOS have any self Certification tool which allows OEMs/Vendors to qualify the OS and post it in their compatibility matrix? One we start our qualification, we might need some help in resolving issues/defects on CentOS. Can we open a channel or Point of contact who will be able to help us out with such issues. I would also request to forward this email to the right forum if the mailing list we are sending to is not the appropriate one. Thanks and Regards. Kumar Ranjan LSI Technologies.

WD RE4-GP Dropped From Raid
by Steve Brooks 01 Apr '11

01 Apr '11

Hi All, I have a WD RE4-GP which dropped an Adaptec 51645 RAID controller. I ran a smartctl short test on the drive and it failed with a read error. So I ran the Western Digital's own diagnostic software (DLGDIAG), both the short and extended test on the drive and it passed with no errors. So I ran the smartctl short test again and again it failed. I then ran smartctl long test and that also failed at the same logical block address as the short test. Can anyone shed any light on this? Can I RMA the drive even if it passes Western Digital's own tests? Thanks in advance for any advice. Cheers, Steve

script question
by Jerry Geis 31 Mar '11

31 Mar '11

I can do "simply" search and replace with sed. However, I want to setup httpd.conf from a script that changes the default "/" which is presently: <Directory /> Options FollowSymLinks AllowOverride None </Directory> and change it to the following: <Directory /> Order Deny,Allow Deny from all AllowOverride None </Directory> How do you do that with scripts? Basically substitute everything between the two Directory tags. Thanks, Jerry

Re: [CentOS] CentOS Digest, Vol 74, Issue 31
by Cal Sawyer 31 Mar '11

31 Mar '11

thanks for the reply, Phil It would, were udev not inserting USB and/or eSATA drives at /dev/sdb1 and/or /dev/sdc1 and exposing the array to the udev rule intended to handle only removable devices (at sdc or sdd). The array then mounts unpredictably in /media/xxx-sdc1 or sdd1 - not what is wanted - depend on how many removable devices are plugged at the time of rebooting. Of course, a single removable device will camp at sdb, which is out of reach of udev so the whole hotplug thing is broken until someone removes all of the devices at site, allowing a clean boot. mapper correctly places the / filesystem higher in position in rc.sysinit, followed by start_udev (where the damage gets done) and finally fstab evaluation way down the line. I suppose i could just hardwire the array mount into rc.sysint to engage after modules get loaded and hopefully before start_udev, unless there is a better way to enforce it. I'm not sure at this stage (need to analyse that ~1000-line script) if there is a suitable insertion point. It would be really good if it could be done outside of rc.sysint in some predictable place. We're "stuck" (but not unhappily) with this kernel/rev for the foreseeable future - i have over 100 of these systems and they are housed behind VPN'd networks, which mitigates somewhat their inevitable vulnerabilities. regards, - csawyer 30. Re: Controlling the order of /dev/sdX devices? (Phil Schaffner) CentOS 5.4(final) 2.6.18-164el5PAE. I am trying to prevent removable USB and eSATA devices from occupying /dev/sdX devices ahead of a 3ware RAID controller. For example: at boot, if a USB drive and eSATA HDD (connected to an LSI 1068E onboard controller, reflashed in "IT" mode to handle hotplug devices) were both present, they would occupy devices /dev/sdb and /dev/sdc, ahead of the RAID controller which ends up as /dev/sdd. As these are removable devices, they should normally get handled by custom udev script looking for adds matching KERNEL=="sd[c-z][0-9]" ,SUBSYSTEM=="block", so the volume handled by RAID controller gets grabbed by udev but fails to mount and subsequent udev plug events fails due the slots left empty below /dev/sdd. If no hotplug devices are present while booting, fstab handles mounting of the system and RAID volume: SATA system HDD /dev/VolGroup00/LogVol00 / RAID array LABEL=STORE /store ## mounts == /dev/sdb1 I realise this description is kind of a tangle, but i am essentially looking for a way to hard-map the 3ware RAID controller to /dev/sdb (UUID won't work as there are multiples of this system) before PCI (?) enumeration picks up the USB and LSI-managed devices so that udev can take care of the device at /dev/sdc and above. I've tried blacklisting the mpt and usb-storage modules and short-circuiting SUBSYSTEM=="block" devices in 05-udev-early.rules, all with zero or negative effect. rc.sysinit doesn't appear to be the right place and that's about as deep down as i know how to go. cheers, cs ------------------------------ Message: 30 Date: Thu, 31 Mar 2011 10:24:42 -0400 From: Phil Schaffner <Philip.R.Schaffner(a)NASA.gov> Subject: Re: [CentOS] Controlling the order of /dev/sdX devices?

Virtualization platform choice
by Jussi Hirvi 31 Mar '11

31 Mar '11

Some may be bored with the subject - sorry... Still not decided about virtualization platform for my "webhotel v2" (ns, mail, web servers, etc.). KVM would be a natural way to go, I suppose, only it is too bad CentOS 6 will not be out in time for me - I guess KVM would be more mature in CentOS 6. Any experience with the free "VMware vSphere Hypervisor"?. (It was formerly known as "VMware ESXi Single Server" or "free ESXi".) http://www.vmware.com/products/vsphere-hypervisor/overview.html I would need a tutorial about that... For example, does that run without a host OS? Can it be managed only via Win clients?

nlockdmgr listen on privileged port
by Tim Dunphy 31 Mar '11

31 Mar '11

hey list! I am attempting to shore up some centos machines (ranging from centos 5 to centos 5.4) for pci compliance by changing the port that nlockdmgr listens on to function under a privileged port. So what I did was try to hardcode the port by editing /etc/sysconfig/nfs # TCP port rpc.lockd should listen on. LOCKD_TCPPORT=1011 # UDP port rpc.lockd should listen on. LOCKD_UDPPORT=1011 # And /etc/modprobe.conf alias eth1 e1000e alias scsi_hostadapter 3w-9xxx alias scsi_hostadapter1 usb-storage alias eth0 e1000e options lockd nlm_udpport=1011 options lockd nlm_tcpport=1011 and then restarting the pormap service. I've even tried restarting the network service, but unfortunately nothing seems affected: [root@stallion:/etc/init.d] $ rpcinfo -p program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 100021 1 udp 55394 nlockmgr 100021 3 udp 55394 nlockmgr 100021 4 udp 55394 nlockmgr 100021 1 tcp 33704 nlockmgr 100021 3 tcp 33704 nlockmgr 100021 4 tcp 33704 nlockmgr 100024 1 udp 786 status 100024 1 tcp 789 status Does anyone have any tips on how to get this to work the way I'm asking it to? regards ~ GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

32-bit compat-gcc on 64-bit CentOS?
by Alan M. Evans 31 Mar '11

31 Mar '11

Ugh. One of our internal servers crashed so bad I just went out and bought a new machine to replace it. The old server was Pentium-4 based and running CentOS-5. When I installed CentOS on the new machine, I used the 64-bit version, partly because that habit is almost automatic nowadays, and partly because the new machine has 6GB of RAM, so 32-bit seemed not very appropriate. Anyway, I've managed to configure every one of the old server's many functions to match on the new server but one: I need the 32-bit version of compat-gcc-34. (Or at least I need to be able to compile 32-bit binaries with the already available version.) I can't seem to do this; am I just missing something? In retrospect, installing the 64-bit OS may have been foolish. But it's too late now. I've spent several days installing/loading/configuring this system to the point it's at now. It would be a pity to have to start over completely just to enable this one (very critical) function. -Alan

Centos+AD integration (uid/gid problems)
by nux＠li.nux.ro 30 Mar '11

30 Mar '11

Hi, I need to have several EL machines in an AD env. Joining the machines was easier than expected using authconfig, but what happens now is that blahdomain\blahuser gets assigned a different, random ID each time I use a different station. In AD I did specify the UID and GID in the UNIX Attributes tab for blahuser, but it gets totally ignored; so do the other values (for home, shell etc). Ideally I'd have all the users assigned a static uid and gid from AD and have /home on all machines mounted from NFS; but right now if I log in with blahuser to another machine my $HOME is owned by another random id. Sugesstions? What am I missing? I'm quite a noob with Windows :) Cheers

OT: virtual host for apache/tomcat servers

I hope someone here can answer my question so I don't have to join another mailing list, on too many as it is... I have the following installed: httpd-2.2.3-43.el5.centos.3 tomcat5-5.5.23 I have a small jsp app that I can hit through apache like: http://www.mydomain.com/tomcat/myapp.jsp So tomcat in the url above is the apache proxy address for the tomcat server. I want to setup a virtual host in apache to automatically load this app if I type: http://myapp.mydomain.com I'm having trouble figuring this out. If I try to setup a virtual host, apache complains that /tomcat is not a valid DocumentRoot. Looking at tons of docs, but not seeing the solution. Any help is appreciated. Thanks, James

centos server network speed check???
by mcclnx mcc 29 Mar '11

29 Mar '11

we have several servers on same rack and servers are all inside firewall. Centos version from 4.X to 5.X. sometime the connection are very slow (compare to servers on other racks also inside firewall). we discuss with network engineer he ask us use "ping" and traceroute" to check. Both tools response time are good but if we connect through application like Web browser, database, or DELL OPMN tool. The response time is very very slow. This situation normally last 4 to 5 hours then it back to normal. Does there has way to check "real" network response time so we can show to network engineer. Otherwise they always say "no problem". Thanks.
