PHP file upload limit
by Boris Epstein 11 Jun '10

11 Jun '10

Hi all, I am trying to run a web-based PHP application on a CentOS 5 32-bit machine that requires me to upload large files. The machine also happens to have little RAM (256MB). I have no problem setting my upload limit ( upload_max_filesize ) to 1 GB but for some reason 2 GB or above seems to be no go. Would anybody know why? Could it be one of the many 32-bit vs 64-bit issues? Thanks. Boris.

software raid - better management advice needed
by aurfalien＠gmail.com 11 Jun '10

11 Jun '10

Hi, I've used mdadm for years now to manage software raids. The task of using fdisk to first create partitions on a spare drive sitting on a shelf (raid 0 were my 1st of 2 drives failed) is kind of bugging me now. After using fdisk to create the same partition layout on the new drive as is on the existing drive and then using mdadm to finish every thing up is a little tedious. Any one have an idea how to have a sort of hot plug were I just swap out the drive and it rebuilds? - aurf

What is the best way to monitor the total incoming / outcoming network traffic of CentOS server. I think that the solution is to monitor the network interfaces and to send SNMP packets to remote server. But is it possible? regards

Service monitoring/"Monit"?
by Toralf Lund 11 Jun '10

11 Jun '10

Has anybody here tried the "Monit" utility (http://mmonit.com/monit/)? I need to set up some kind of "watchdog" functionality for a custom service otherwise started via init (i.e. via a script in /etc/init.d + rc*.d links managed by chkconfig) and it seems like this system may give me nearly what I want. However, something that concerns me about it, is that it appears to take full ownership of the services it monitors, and pretty much bypass the init system, in that once I've told monit to watch a process, it makes not difference if the associated service is enabled or not (via "chkconfig") , and there is no good way to fully stop the service, besides removing the Monit config or disabling Monit itself. (Or maybe I can use special "monit" commands, too, but that means precisely that Monit "owns" the service, which I somehow don't quite like.) What I'd really like, is to have my process watched and restarted if it goes a way, but only if it had already been started via "init" or through the "service" command, or possibly direct execution of the "init.d" script. This also means it should be restarted if it crashes or if is stopped via a direct "kill", but not after "service <name> stop" or similar. Which might mean it all boils down to checking if, and only if, the pid file for the service already exists. (Does that make any sense?) So, does anyone know if there is a way to convince Monit to do this for me? Or alternatively, is there a different tool that might do the job? And yes, I know it shouldn't be that hard to design a program/script/cron job to do it all for me, but I still think not having to maintain another software component would be nice... - Toralf This e-mail, including any attachments and response string, may contain proprietary information which is confidential and may be legally privileged.

DHCP/DNS server for LAN with mainly Windows clients : Outlook Express vs. Webmail problem
by Niki Kovacs 11 Jun '10

11 Jun '10

Hi, I recently setup a CentOS 5 file server for a small LAN consisting of 15 Windows XP clients. The LAN is eventually expected to migrate to Linux, at least some of the client machines. The previous setup made by a local Windows-only computer firm was an unhealthy mix of static and dynamic IP addresses with conflicting adresses, etc. First thing I undertook was clean up this mess by setting up a DHCP + local cache DNS server on the Linux machine. Now the curious problem I have: IP addresses are attributed correctly, people can surf on the internet all right. But the only thing they can't seem to do is send mail with Outlook or Outlook Express. I have to revert to the ISP's DNS, but so I lose the benefit of local DNS. And I don't have the slightest clue as to why that is so. Here's my setup, maybe one of the gurus on the list has an idea: 1) /etc/dhcpd.conf (the fixed addresses are attributed because the local printer has a page counting device that works with IP adresses): --8<--------------------------------------- ddns-update-style interim; authoritative; default-lease-time 86400; max-lease-time 86400; option broadcast-address 192.168.0.255; option subnet-mask 255.255.255.0; option routers 192.168.0.1; option domain-name-servers 192.168.0.2; option domain-name "regards.arles"; subnet 192.168.0.0 netmask 255.255.255.0 { range 192.168.0.100 192.168.0.150; } host poste1 { hardware ethernet 00:26:18:B7:D6:10; fixed-address 192.168.0.101; option host-name "poste1"; } host poste2 { hardware ethernet 00:24:81:69:A3:DE; fixed-address 192.168.0.102; option host-name "poste2"; } host poste3 { hardware ethernet 00:1B:FC:6F:66:2C; fixed-address 192.168.0.103; option host-name "poste3"; } ... --8<--------------------------------------- For setting up Bind, I used a "dummy" domain name, like I usually do in LAN's. For example, my home network is "presbytere.montpezat", the local town hall's network is "mairie.montpezat". The network here is "regards.arles". ("Regards" is the name of a local association, and "Arles" is the city in South France where it's located). 2) /etc/named.conf: --8<--------------------------------------- options { directory "/var/named"; listen-on { 127.0.0.1; 192.168.0.0/24; }; }; zone "." IN { type hint; file "named.root"; }; zone "localhost" IN { type master; file "zone.localhost"; allow-update { none; }; }; zone "0.0.127.in-addr.arpa" IN { type master; file "revp.127.0.0"; allow-update { none; }; }; zone "regards.arles" IN { type master; file "zone.arles.regards"; }; zone "0.168.192.in-addr.arpa" { type master; file "revp.192.168.0"; }; --8<--------------------------------------- 3) /var/named/named.root: --8<--------------------------------------- ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5 <<>> ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 42704 ;; flags: qr rd ra; QUERY: 1, ANSWER: 13, AUTHORITY: 0, ADDITIONAL: 14 ;; QUESTION SECTION: ;.

operation on the client is slow when openldap servers are down

  @import url( C:\Documents and Settings\Administrator\Local Settings\Temporary Internet Files\scrollbar.css ); Hi List,   OS: centos5.3 x86_64 OpenLDAP is installed using yum.   I find that when all the ldap servers are down and offline, the operations on the client is slow.

md0 and moving to another system
by aurfalien＠gmail.com 11 Jun '10

11 Jun '10

Hi all, I thought to have tested this a while ago but I guess not. I have a Centos 5.3 system (call its SYSA) software raid 0, 2 disks. I have an identical system (SYSB) else were, so I pull one of my mirrors drives from SYSA and put it in SYSB as the only drive in SYSB. Upon but I get grub error. I boot in recuse mode (CD, linux rescue) and it attempts to mount the disk, but claims no partitions exists. I drop into a shell and mount it w/o issues. Running fdisk on the drive tells me its got 2 partitions which is true. I set this up as ext3, no LVMs, etc... with root and the other partition being swap. I've always thought that all I can do in the event of motherboard failure os to have a duplicate system around and merely move a dive off to it. - aurf

Openwebmail dependency problem

Intel ICH10R on CentOS 5.4
by nate 10 Jun '10

10 Jun '10

Hey there.. I was wondering if anyone could share experiences they have had with the Intel ICH10R SATA controller? I tried looking around but all I could find were RAID references, I have no interest in using the RAID functionality just basic SATA JBOD. Wondering if there are any gotchas for performance, drivers, quality etc. I normally don't touch anything that is not hardware RAID though this is a special project.. And even if I get demo gear I won't have enough time to put it through real paces(likely need weeks) before a decision needs to be made. I don't see anything that is causing alarm but just curious if anyone else has experiences. thanks nate

Re: [CentOS] PHP file upload limit

Plus at that point you might also be hitting problems with browser behaviour.... since you say it is a web app.... 2 gigs is a heck of a post... have you looked into any other solutions such as an uploader in flash or java capable of resuming transfers and streamed (partial) transfers rather than a single post?

Other PHP settings, like post_max_size, also can affect large uploads. Google is your friend on this.

MAC address changes after cloning
by premrajm＠digilink.in 09 Jun '10

09 Jun '10

Hi, I have x86 system and have used clonezilla to clone the entire hardisk of system A and restored it on another x86 system, system B. After the cloning process, i notice that the MAC address of the system B in the /etc/sysconfig/network-scripts/ifcfg-eth0 is changed and is having the MAC address of system A. The interesting part is that if i do an ifconfig from the bash prompt, the MAC address of the system B is correctly displayed, but in ifcfg-eth0 script it is different. I had disabled kudzu, since i was always getting eth1 activated on System B, even though i had used eth0 on system A. eth0.bak was getting created instead on system B. Disabling kudzu resolved it. My question is that how could i get the same MAC address for system B from ifconfig and in /etc/sysconfig/network-scripts/ifcfg-eth0. Is there any script to do it ?

rpm building and hyphens in Version tags
by Joseph L. Casale 09 Jun '10

09 Jun '10

According to http://www.rpm.org/api/4.4.2.2/specfile.html a Version: tag can contain a hyphen, as the tarball for the source I am compiling is named 2.3-pre4 etc. When I try to build it I get an error about the illegal char? Anyone know about the discrepancy between the docs and RHEL's rpmbuild? Without recreating a new tarball and bungling the name how does one gracefully handle this? Thanks! jlc

ls -lrt reversal
by Michael D. Berger 09 Jun '10

09 Jun '10

My CentOS box with: $ uname -r 2.6.18-164.6.1.el5 gets the file order wrong with: ls -lrt * . Two files that were last modified in the same second are shown in order that is the reverse of the order in which they were actually last modified. Note also that the later file was first created after the earlier file was last modified. Is the precision of this only to the second? Mike.

SOLVED annoying firefox crash on nvidia
by Paul Bijnens 09 Jun '10

09 Jun '10

A long time ago, there was thread about firefox randomly crashing. http://www.mail-archive.com/centos@centos.org/msg50010.html It turned out not only firefox, but random other X window applications as well. Especially scrolling in firefox seemed to induce the error. I'm now since almost 2 weeks up and running with the same firefox instance and scrolling up/down, left/right, playing video's, viewing websites with heavy javascripts whatever, and without any crash since. I use the proprietary driver NVIDIA-Linux-x86_64-195.36.24-pkg2.run (the latest last time I looked). I believe the cullprit was to explicitly load some modules in the xorg.conf file. (It is probably the "extmod" module -- there is almost no real documentation on what those modules actually do...) While the nvidia driver installs, there is an utility that generates the new xorg.conf file for you, having only one module "glx" loaded. This seems to be source of the trouble. Gnome seems to assume more functionality is available, and does not gracefully recover when asking something that is not implemented in those extra modules. Since adding some more modules, I have no more crashes: Section "Module" Load "dbe" Load "extmod" Load "type1" Load "freetype" Load "glx" Load "fbdevhw" Load "record" EndSection And, as added benefit, or side effect, the memory usage of my gnome applets has drastically gone down. I used to see a simple clock-applet having using 800 Mbyte virtual memory or so and having 400M reported under the "resident memory" column. Other people also reported such a problem, but it was frequently dismissed by explanations like "gnome uses a lot of shared memory it is not real memory". I now have my clock and other gnome applets running in under 300M virtual, 10-14M resident memory (if you ask me, still large for clock -- where is the time when I ran a whole unix with 5 serial terminals and the server had 1 Mbyte RAM total memory on a motorola 68010 processor?) -- Paul Bijnens *********************************************************************** * I think I've got the hang of it now: exit, ^D, ^C, ^\, ^Z, ^Q, ^^, * * quit, ZZ, :q, :q!, M-Z, ^X^C, logoff, logout, close, bye, /bye, ~., * * stop, end, ^]c, +++ ATH, disconnect, halt, abort, hangup, KJOB, * * ^X^X, :D::D, kill -9 1, kill -1 $$, shutdown, init 0, Alt-F4, * * Alt-f-e, Ctrl-Alt-Del, Alt-SysRq-reisub, Stop-A, AltGr-NumLock, ... * * ...

Created a custom/minimal CentOS 5.x install ISO
by Digimer 09 Jun '10

09 Jun '10

Hi all, I'd like to try rolling a somewhat stripped down and customized CentOS DVD. This is particularly interesting to me now that CentOS 5.5 is 2 DVDs. I dare not call it a new distro as I suspect I will be the only one to use it. ;) I've been googling for ways to do this, figuring it must be somewhat straight forward, but my google-fu is weak it seems. Can someone point me to a how-to or doc on rolling your own CentOS derivative ISO? Also, I'm not talking about just rolling a new ISO, I can do that already, I want to update the list of RPMs (not)available to the installer. Thanks! PS - I found this link, but it's from 2006. Otherwise it's in-line with the kind of thing I want to do: http://lateral.netmanagers.com.ar/stories/38.html -- Digimer E-Mail: linux(a)alteeve.com AN!Whitepapers: http://alteeve.com Node Assassin: http://nodeassassin.org

Odd INFO "120 seconds" in logs for 2.6.18-194.3.1
by Steve Brooks 08 Jun '10

08 Jun '10

Hi, Since upgrading to "2.6.18-194" I am getting odd messages in the logs. Such as; sraid3 kernel INFO task pdflush 259 blocked for more than 120 seconds. The output from > grep '120 seconds' /var/log/messages | tr : ' ' | awk '{print $10}' | sort | uniq -c 6 nfsd 4 pdflush This is from an NFS server that since the upgrade has been flakey. I have an identical server running "2.6.18-164.11.1" and no such messages are seen. is anyone else seeing this and/or know what is going on?

grub, initrd and Co
by Philippe Naudin 08 Jun '10

08 Jun '10

Hi all, I am trying to boot from a HD created as a copy of a running system (and it doesn't work, and I don't understand why ...) This is the system to be copied : File-system Size Used Avail Use% Mounted on /dev/hda1 2.0G 797M 1.1G 43% / tmpfs 506M 0 506M 0% /dev/shm /dev/hda5 4.7G 3.3G 1.2G 74% /var/spool/squid/cache1 /dev/hda6 4.7G 3.3G 1.2G 74% /var/spool/squid/cache2 The backup of the system has been done with : /bin/tar czO -C / --preserve-permissions --sparse --one-file-system \ --exclude=lost+found --exclude=tmp/* \ . \ | /usr/bin/nc -w 5 my.workstation 6060 # ( after executing # netcat -l -p 6060 > $IMAGE on my.workstation ) On the target HD, I have created three "type 83" partitions and a swap, ran mke2fs -cc -j /dev/$D for the three FS and mkswap -c /dev/$D for the future swap. The target root FS was restored with : tar xzpf $IMAGE -C /mnt/linux On the target root FS, I edited /etc/fstab and /etc/grub.conf, replacing any reference to LABEL=... by the real device (/dev/hda1 and so on). Then I took care of the initrd (future / is mounted on /mnt/linux/) : mount -o bind /dev /mnt/linux/dev mount -t proc none /mnt/linux/proc mount -t sysfs none /mnt/linux/sys rm /mnt/linux/boot/initrd* chroot /mnt/linux mkinitrd /boot/initrd-2.6.18-194.3.1.el5.img 2.6.18-194.3.1.el5 # so far, so good... ... and installed grub on the target HD : /sbin/grub --no-curses find /boot/grub/stage1 # answer : (hd0,0) root (hd0,0) setup (hd0) # answer : succeeded quit exit # (chroot) When I try to boot the target HD (set as hda in a new PC), I get the grub prompt, and I can boot the system. Every thing goes too quickly, so I can't see what is going on, until : ... Trying to resume from /dev/hda3 No suspend signature on swap, not resuming. Creating root device. Mounting root filesystem. mount: error mounting /dev/root on /sysroot as auto: No such device Setting up other filesystems. Setting up new root fs setuproot: moving /dev/failed: No such file or directory no fstab.sys, mounting internal defaults Then it complains about missing /proc and /sys, and end with : switchroot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init! /dev/hda3 is the swap partition on the new disk. The swap was in /dev/hda2 on the old disk, but fstab has been modified accordingly ; other FS are just like on the old disk (I mean, / is hda1, cache1 is hda5 and cache2 is hda6). I have certainly forgotten something, but I am unable to find what... Who can help me ? Thanks, -- Philippe

Is every CentOS release supported for 7 years?
by Aniruddha 08 Jun '10

08 Jun '10

Hi, I've read some posts in the forums which seems to indicate that not every CentOS version is well supported. Is it possible to install CentOS 5.5 on a server and only apply security updates for 7 years? Or is the preferred way to upgrade to each minor version? Thanks in advance! Relevant forum quotes: Probably not relevant to the problem; however, the current release is 5.4 - 5.3 is getting seriously obsolete with respect to security problems and bugs. http://centos.caosity.org/modules/newbb/viewtopic.php?viewmode=flat&order=A… If you really mean 5.0, it is seriously obsolete and has numerous known bugs and security issues that have been fixed in subsequent updates. Obsolete releases are not supported, nor is it advisable to be installing or running them. See the CentOS 5.5 Release Notes for details. https://www.centos.org/modules/newbb/viewtopic.php?topic_id=26339&forum=37

194 Kernel Panic; 164 is Fine; How Do I Debug?
by John Thomas 07 Jun '10

07 Jun '10

I have a machine that has worked fine for years on CentOS5. kernel-PAE-2.6.18-164.15.1.el5 is the last "works fine" kernel, but kernel-PAE-2.6.18-194.3.1.el5 crashes at boot every time. I tried banging on the side of the monitor to no avail. All kidding aside, here are pictures of my monitor when booting 194 in case that is helpful. http://jt-socal.com/sites/jt-socal.com/files/kernel-panic.jpg http://jt-socal.com/sites/jt-socal.com/files/just-before-crashing.jpg Any suggestions on fixing this? -- Sincerely, John Thomas

Package Distribution Server?
by Zhihao Lou 07 Jun '10

07 Jun '10

Dear List, I'm trying to set up a lab with multiple workstations running CentOS 5. Does anybody knows how to keep the packages in sync among workstations? Ideally I want any change made on any machine be able to applied to all other machines. Alternatively, to "push" the changes (add and/or remove packages) from one central server to all other machine is also fine. Thanks Zhihao Lou P.S.: Sorry for the confusion subject line. I really don't know what's the accurate name for the feature I described here.

GRUB, and how do I loathe thee
by m.roth＠5-cent.us 07 Jun '10

07 Jun '10

I just adore the install. Esp. of GRUB. Does *anyone* who works on GRUB actually work in the real world, and not only on brand new machines? I just had happen at work what happened last fall on my home system: then, I had /dev/hda, and was trying a clean install on a new SATA drive; right now, I'm installing on a replacement disk on a server that has no CD/DVD drive from a USB key. My options: on my home system, it was MRR on /dev/hda (which was being replaced, and was to become my backup drive), and here, in the MBR of the USB key; in both cases, *only* in the first sector of a partition on the new drive. I am NEVER OFFERED THE OPTION of the MBR of the drive I'm installing to. *snarl* mark "no grub, then linux rescue, then chcon, then grub install... I hope"

OT: SysAdmin Stories
by Geoff Galitz 07 Jun '10

07 Jun '10

Hello, I'm compiling a collection of stories from the systems administrator trenches. They can be short or long, funny or about a particularly challenging problem or period, or even something that appeared very technically challenging and ended up being something very simple. Stories which are more political would be ok so long as they do not have an agenda or can be interpreted as a public attack. I can't promise money but I can promise 15 minutes of fame. The stories will be accumulated over the next few months and go into a book about real world experiences of Systems Administrators and Systems Engineers. Some of the material may be used in our training classes, as well. All stories will be duly credited and I'll even buy a beer (or other non-alcoholic beverage) for anyone I ever meet in person. Stories may be edited for grammar or clarity. This book is still in the proposal stage so there is no firm target date, yet. If for some reason the book is not published (just like tech projects, books are sometimes cancelled at the last minute) they will go up on our website. Thanks! -Geoff --------------------------------- Geoff Galitz Blankenheim NRW, Germany http://eifel-consulting.biz http://www.galitz.org/ http://german-way.com/blog/

redundant ldap - client config
by aurfalien＠gmail.com 04 Jun '10

04 Jun '10

Hi all, I have a few ldap servers slaved to a primary via syncrepl, all is well. I've set my clients to auth against a few and there /etc/ldap.conf looks like so; uri ldap://primary.domain.com ldap://secondary.domain.com However when either primary or slaves go down, while the clients can log in, access is very slow, ls of any dir is painful. The /var/log/messages shows several failed attempts to conect to the slaves ldap servers. Whats the proper way to set up redundant ldap on the clients?

update from 4.8 to 5.4?
by Robert Tate 04 Jun '10

04 Jun '10

I have searched the list, and don't see this covered or didn't search for the right words. I'm running CentOS 4.8 and have some DVD's for 5.4. I have a lot of customized and additional software installed and would like to avoid starting over with a scratch install. After the upgrade from the DVD I would do a yum upgrade to 5.5. Is this a workable (and safe) thing to do? What should I look out for? I plan to build a clone of the boot disk in case there is a problem so I can swap it back in to the hba1 position (as soon as I find a way to make a clone of a disk with LVM ). Here is some info on the system: [root@hat /]# cat /etc/redhat-release CentOS release 4.8 (Final) [root@hat /]# uname -a Linux hat.rbt.net 2.6.9-89.0.25.ELsmp #1 SMP Thu May 6 12:28:03 EDT 2010 i686 athlon i386 GNU/Linux[root@hat .spamassassin]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VG00-LV00 2.0G 695M 1.2G 37% / /dev/hda1 494M 25M 444M 6% /boot none 1013M 0 1013M 0% /dev/shm /dev/mapper/VG00-LV04 9.9G 5.4G 4.0G 58% /home /dev/mapper/VG00-LV05 1008M 34M 924M 4% /opt /dev/mapper/VG00-LV03 4.0G 41M 3.7G 2% /tmp /dev/mapper/VG00-LV01 7.9G 4.2G 3.4G 56% /usr /dev/mapper/VG00-LV02 4.0G 929M 2.9G 25% /var Thanks in advance for any help with this....

Recommendations for a webcam

04 Jun '10

hi, I am looking for recommendations for a webcam that works out of the box( or something that does not need major work getting going ) on CentOS-5. But I also need it to do : Better than 640x480, have the ability to work in low light and stream via vlc. I have a Philips SPC 900nc which looks good on paper, and just works, but its unable to really do better than 320x240 and its low light performance is quite sad. I've also tried using a logitech quick cam 9000 pro. Which suffers about the same fate. It does manage to get upto 640x480, but at a fairly average end result. Recommendations ? - KB

small touchscreen/ side monitor for access control application
by R P Herrold 04 Jun '10

04 Jun '10

A couple months ago there was an inquirant looking for a small, wall mountable monitor to provide an display and input device for entrance control on an area. Think Geek was out of stock on a possible offering, but just came back. I just received this notification of availabity Mimo Mini USB Monitor - 720-S Slider Touch http://www.thinkgeek.com/computing/usb-gadgets/bfa3/ I have no interest in this referral, beyond the hope of later receiving reports of people succeeding (and writing up) their adaptation of such to CentOS -- Russ herrold

Re: [CentOS] Logwatch, cron, and dovecot
by Bob Hoffman 03 Jun '10

I think I found it...and I think it is a bug. Here is a file in usr/share/logwatch/default.conf/logfiles/cron.conf It appears this file tells it where to look for the cron file...and the cron file location is dead wrong. It should be /var/log/cron I believe. Is this the correct fix to make logwatch once again grab my cron files since 5.5 update? ########################################################################## # $Id: cron.conf,v 1.11 2005/02/24 17:05:18 kirk Exp $ ########################################################################## ######################################################## # This was written and is maintained by: # Kirk Bauer <kirk(a)kaybee.org> # # Please send all comments, suggestions, bug reports, # etc, to kirk(a)kaybee.org. ######################################################## # What actual file?

SUN Storage 7310 with RHEL 5.5 / Centos 5.5 and multipathed root, again.
by Jens Neu 03 Jun '10

03 Jun '10

Dear all, After some trouble finding the right multipath.conf, I'm running Centos 5.5 against the SUN 7310 more or less successfully now. Unfortunately one issue remains: the SUN 7310 has two storage heads, H1 and H2, which are in a active/passive configuration. If I define a LUN on H1, everything works great. I edit multipath.conf, re-create the initrd and I find 8 paths with active/ready and active/ghost: mpath0 (3600...0001) dm-0 SUN,Sun Storage 7310 [size=50G][features=1 queue_if_no_path][hwhandler=0][rw] \_ round-robin 0 [prio=200][active] \_ 0:0:0:0 sda 8:0 [active][ready] \_ 0:0:1:0 sdd 8:48 [active][ready] \_ 1:0:0:0 sdg 8:96 [active][ready] \_ 1:0:1:0 sdj 8:144 [active][ready] \_ round-robin 0 [prio=4][enabled] \_ 1:0:2:0 sdm 8:192 [active][ghost] \_ 0:0:2:0 sdn 8:208 [active][ghost] \_ 1:0:3:0 sds 65:32 [active][ghost] \_ 0:0:3:0 sdt 65:48 [active][ghost] Thing is: as soon as I set up a machine with the LUN(s) on the second head, all works well until I want to boot with the freshly created initrd/multipath.conf. System hangs with Kernel Panic, "Creating multipath devices... no devices found" and "mount: could not find filesystem '/dev/root'". Workaround: when I remove the paths to the passive ("ghost paths") Storage head in the SAN Fabric, the system boots fine and I can re-enable the paths when the kernel is up. The paths become [active][ghost] as wished after some time when they show up in the FC Zoning. This smells like broken mkinitrd to me. System is very up-to-date, Centos 5.5 Version below: [root@dev-db3 ~]# yum list device-mapper-multipath Installed Packages device-mapper-multipath.x86_64 0.4.7-34.el5_5.1 installed [root@dev-db3 ~]# uname -r 2.6.18-194.3.1.el5 Any suggestions? best regards from Berlin, Jens Neu Health Services Network Administration

Logwatch, cron, and dovecot
by Bob Hoffman 03 Jun '10

03 Jun '10

Howdy all, Question for anyone. I have centos 5.x on my server. Everyday I get a logwatch sent to my mailbox. I usually check every couple weeks and this time I got a surprise... Up until may 15th, the watch started with cron begin/ cron end and then went to http begin/end.... May 16th had the selinux (which I have disabled) and dovecot listings above the http begin. Cron was absent. Everyday after that is is all dovecot first, no cron. I never had dovecot show up in my logwatch before. So, I assume some update did something, but it was obviously 2 weeks ago or so. I have an auto update, so I am thinking it happened with a yum update. The selinux only happened that one time...not shown up since. I am concerned about the cron begin/end no longer being there, don't know why dovecot was not there to begin with.... Just did a reboot and will see what happens tomorrow... Thanks for any help at all. --------------------- Selinux Audit Begin ------------------------ Number of audit daemon starts: 1 Number of audit daemon stops: 1 **Unmatched Entries** Started dispatcher: /sbin/audispd pid: 21352 ---------------------- Selinux Audit End ------------------------- --------------------- Dovecot Begin ------------------------

pup problem
by Charles Campbell 03 Jun '10

03 Jun '10

Hello! On May 28, I had a problem with pup and seamonkey. I was doing an update via pup and reading a page via seamonkey; seamonkey froze with a plain brown screen. I waited awhile, and then did the press-the-power-button-until-it-shuts-off. However, I don't know whether it was seamonkey or pup that actually caused the freeze, but apparently pup did not do its updating job correctly. There's a number of icons that are missing, so (for example) open office won't start from the menu. Centos starts, but the desktop background doesn't appear (although I can select desktop background and get it to appear). Finally, attempts to attach anything to an email via seamonkey (17 or 2.04) or thunderbird show the requestor momentarily and then crashes seamonkey/thunderbird. Is there a log somewhere of what was updated (I didn't see it in /var/log/messages) and can I force pup to do the update manually? Any other suggestions for getting things back to normal? Regards, Chip Campbell

Can't print a pdf?
by MHR 02 Jun '10

02 Jun '10

I just had a strange occurrence. I was printing out some PDFs and I pulled one down off the web (my wireless bill) and tried to print page 1. My browser properly fired up AR9, but nothing printed. I tried agian, still nothing. I saved the file, opened it with the Document Viewer and it can't print the file either. I tried opening it with GIMP, and it gets this error: Opening '/home/mhr/Documents/pdfs/vzwA0418.pdf' failed: Plug-in could not open image I couldn't find any related data in the logs (spooler logs are all empty, nothing in dmesg). I tried disabling and enabling the printer, then turning it off and on to no effect (which is not too surprising). Anyone have a clue where I should look or what to do? Thanks. mhr

24G running on centos 5 desktop.
by Steve Brooks 02 Jun '10

02 Jun '10

Hi All, Thought I would let those that are interested know that I had success in running 24G on an Asus P6T with 24G kit of Kingston DDR3. While I was putting this together I saw lots of forum posts asking if anyone had tried it. Well we did here at our work and all looks great including running "memtest86" overnight. I have a fluid dynamics simulation running on it with 90% memory usage and all looks great.

bogus bond0 device showing up in /proc/net/dev
by Tom Georgoulias 02 Jun '10

02 Jun '10

I'm running into a situation where a bogus bonded interface named "bond0" is being created, in addition to the desired "bond2" interface. Can anyone confirm this? Anyone know why it's happening or what I do to get rid of it? I wanted to start my numbering scheme at 2 instead of 0, which I didn't think would be a problem. As you can see, I have no reference to bond0 in any of my configs: # grep bond /etc/modprobe.conf alias bond2 bonding # ifconfig -a | grep bond bond0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 bond2 Link encap:Ethernet HWaddr XXXXXXXXXXXXXXXXX # cat /etc/sysconfig/network-scripts/ifcfg-bond2 DEVICE=bond2 IPADDR=XXXXXXXXX NETMASK=XXXXXXXX NETWORK=XXXXXXXXX USERCTL=no BOOTPROTO=none ONBOOT=yes BONDING_OPTS="mode=1 miimon=100" # cat /etc/sysconfig/network-scripts/ifcfg-eth2 DEVICE=eth2 MASTER=bond2 SLAVE=yes HWADDR=XXXXXXXXXXXX ONBOOT=yes BOOTPROTO=none USERCTL=no # cat /etc/sysconfig/network-scripts/ifcfg-eth3 DEVICE=eth3 MASTER=bond2 SLAVE=yes HWADDR=XXXXXXXXXX ONBOOT=yes BOOTPROTO=none USERCTL=no The bond0 interface isn't doing any harm, as far as I can tell, except adding bogus data to ifconfig output and extra, useless charts in our system performance monitoring tools. # cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.4.0 (October 7, 2008) Bonding Mode: load balancing (round-robin) MII Status: down MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms): 0 # cat /proc/net/bonding/bond2 Ethernet Channel Bonding Driver: v3.4.0 (October 7, 2008) Bonding Mode: fault-tolerance (active-backup) Primary Slave: None Currently Active Slave: eth2 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth2 MII Status: up Link Failure Count: 0 Permanent HW addr: XXXXXXXXXXXX Slave Interface: eth3 MII Status: up Link Failure Count: 0 Permanent HW addr: XXXXXXXXXXXXXX Any help is appreciated.
