CentOS 4.4 lvm and drbd 0.8?
by Chuck Mattern 04 Mar '07

04 Mar '07

I'm running CentOS 4.4 and drbd 0.7 with ext3 filesystems on the drbd device. I'm very interested in moving to drbd 0.8 and pulling my all of my drbd devices into one lvm for greater flexibility in filesystems. I've seen some notes on doing this but wonder if anyone on this list has a cookbook for doing this. Also noted that on the drbd site the only packages they have are set up for the 2.6.9-34.106 kernel. Any thoughts on when there might be a drbd .8 package for the current kernel? Thanks for any wisdom on this, Chuck

php-4.4 rpm
by Michael Kress 04 Mar '07

04 Mar '07

Hi, has somebody already succeeded in creating a php-4.4 rpm under centos-4.4? php version 4.3.9 compiles perfectly, but taking the 4.3.9 spec and replacing the source tar.gz (and omitting the patches) doesn't work at all. I could provide you with details about compile errors, but I think I should check the availability of a 4.4 package before trashing you with details. TIA Regards Michael -- Michael Kress, kress(a)hal.saar.de http://www.michael-kress.de / http://kress.net P E N G U I N S A R E C O O L

Skype on CentOS??
by Doc Schneider 03 Mar '07

03 Mar '07

I'm just curious if Skype will work on CentOS? They have all kinds of FC rpms but which one to install? I'm running CentOS 4.4 I tried the Live CD just to test and it didn't want to find my sound card (Tried the sound card detection on the CD). But, I'm sure, that is a configuration issue and can be works out with ALSA. TIA, -- -Doc Lincoln, NE. http://www.genealogyforyou.com/ http://www.cairnproductions.com/

Swap Considerations
by Mike McCarty 03 Mar '07

03 Mar '07

I am considering installing CentOS 4.4, and am interested in how best to set up. I have been using FC2 and helping administer a Debian machine for a few years, but do not consider myself a Linux guru. My current set up uses a /swap partition which is 2x my memory size mem = 256 MB $ sudo /sbin/fdisk -l /dev/hda6 76506 77545 524128+ 82 Linux swap I'm interested in the use of a file for swap, as I hear that there is now no speed penalty for that. I use ext3 for my partitions. I'm also interested in whether it be reasonable/desirable to make /home, /tmp, and /var be on a separate partition. I have heard arguments on both sides, some claiming that with ext3 the system won't become unbootable because of /tmp filling up. Anyone care to weigh in?

Storage/SCSI Error on our CentOS server
by Hairul Ikmal Mohamad Fuzi 02 Mar '07

02 Mar '07

Hi, Currently we are running CentOS 4.x on a 2-way Opteron machine. This machine, through a SCSI host adapter (Adaptec), is connected to a 2TB storage unit (an external RAID-5 disk array) Until our recent unintentional power trip, everything was fine and smooth. We have been experiencing complication accessing the storage ( it could be either intermittent filesystem error, partition could not be mounted in read-write mode, unacceptable writing speed, etc ), especially when we start to 'write' on the storage. After a few check, we are suspecting either : 1) the storage unit (but the storage control panel did not report any disk/raidset failure) is failing or, 2) the SCSI host adapter is failing, or 3) the filesystem itself is corrupted (we did 'fsck.ext3 -v -f' but it turned out it did not find any errors) ..but we are not sure which one.We did received 'messages' which we never experience previously in our 'dmesg' . (please refer below) Based on the above info and the below 'dmesg' output, we'd appreciate if somebody could share and help us to identify what actually went wrong and how could fix it (if possible)? TIA. -Ikmal Dmesg output : =========================================== scsi4:0:0:0: Attempting to abort cmd 0000010082297a80: 0x28 0x0 0x0 0x0 0x1 0x3f 0x0 0x0 0x8 0x0 scsi4: At time of recovery, card was not paused >>>>>>>>>>>>>>>>>> Dump Card State Begins <<<<<<<<<<<<<<<<< scsi4: Dumping Card State at program address 0xc Mode 0x33 Card was paused HS_MAILBOX[0x0] INTCTL[0x80] SEQINTSTAT[0x0] SAVED_MODE[0x11] DFFSTAT[0x33] SCSISIGI[0x0] SCSIPHASE[0x0] SCSIBUS[0x0] LASTPHASE[0x1] SCSISEQ0[0x0] SCSISEQ1[0x12] SEQCTL0[0x0] SEQINTCTL[0x0] SEQ_FLAGS[0xc0] SEQ_FLAGS2[0x0] SSTAT0[0x0] SSTAT1[0x0] SSTAT2[0x0] SSTAT3[0x0] PERRDIAG[0xc0] SIMODE1[0xa4] LQISTAT0[0x0] LQISTAT1[0x0] LQISTAT2[0x0] LQOSTAT0[0x0] LQOSTAT1[0x0] LQOSTAT2[0x0] SCB Count = 4 CMDS_PENDING = 1 LASTSCB 0xffff CURRSCB 0x2 NEXTSCB 0x0 qinstart = 59 qinfifonext = 59 QINFIFO: WAITING_TID_QUEUES: Pending list: 2 FIFO_USE[0x0] SCB_CONTROL[0x64] SCB_SCSIID[0x7] Total 1 Kernel Free SCB list: 3 1 0 Sequencer Complete DMA-inprog list: Sequencer Complete list: Sequencer DMA-Up and Complete list: scsi4: FIFO0 Free, LONGJMP == 0x80ff, SCB 0x0 SEQIMODE[0x3f] SEQINTSRC[0x0] DFCNTRL[0x0] DFSTATUS[0x89] SG_CACHE_SHADOW[0x2] SG_STATE[0x0] DFFSXFRCTL[0x0] SOFFCNT[0x0] MDFFSTAT[0x5] SHADDR = 0x00, SHCNT = 0x0 HADDR = 0x00, HCNT = 0x0 CCSGCTL[0x10] scsi4: FIFO1 Free, LONGJMP == 0x81d8, SCB 0x3 SEQIMODE[0x3f] SEQINTSRC[0x0] DFCNTRL[0x0] DFSTATUS[0x89] SG_CACHE_SHADOW[0x2] SG_STATE[0x0] DFFSXFRCTL[0x0] SOFFCNT[0x0] MDFFSTAT[0x5] SHADDR = 0x00, SHCNT = 0x0 HADDR = 0x00, HCNT = 0x0 CCSGCTL[0x10] LQIN: 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 scsi4: LQISTATE = 0x0, LQOSTATE = 0x0, OPTIONMODE = 0x52 scsi4: OS_SPACE_CNT = 0x20 MAXCMDCNT = 0x0 SIMODE0[0xc] CCSCBCTL[0x0] scsi4: REG0 == 0xffff, SINDEX = 0x1e0, DINDEX = 0xe1 scsi4: SCBPTR == 0x3, SCB_NEXT == 0x2, SCB_NEXT2 == 0x2 CDB 28 0 0 80 19 ac STACK: 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 <<<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>> DevQ(0:0:0): 0 waiting (scsi4:A:0:0): Device is disconnected, re-queuing SCB Recovery code sleeping Recovery SCB completes Recovery code awake scsi4: Transmission error detected LQISTAT1[0x0] LASTPHASE[0x1] SCSISIGI[0x0] PERRDIAG[0x1] >>>>>>>>>>>>>>>>>> Dump Card State Begins <<<<<<<<<<<<<<<<< scsi4: Dumping Card State at program address 0x26 Mode 0x11 Card was paused HS_MAILBOX[0x0] INTCTL[0x80] SEQINTSTAT[0x0] SAVED_MODE[0x11] DFFSTAT[0x33] SCSISIGI[0x1a] SCSIPHASE[0x1] SCSIBUS[0xff] LASTPHASE[0x1] SCSISEQ0[0x40] SCSISEQ1[0x12] SEQCTL0[0x0] SEQINTCTL[0x0] SEQ_FLAGS[0xc0] SEQ_FLAGS2[0x0] SSTAT0[0x10] SSTAT1[0x11] SSTAT2[0x0] SSTAT3[0x0] PERRDIAG[0x0] SIMODE1[0xac] LQISTAT0[0x0] LQISTAT1[0x0] LQISTAT2[0x0] LQOSTAT0[0x0] LQOSTAT1[0x0] LQOSTAT2[0x0] SCB Count = 4 CMDS_PENDING = 1 LASTSCB 0xffff CURRSCB 0x2 NEXTSCB 0x0 qinstart = 61 qinfifonext = 61 QINFIFO: WAITING_TID_QUEUES: 0 ( 0x2 ) Pending list: 2 FIFO_USE[0x0] SCB_CONTROL[0x50] SCB_SCSIID[0x7] Total 1 Kernel Free SCB list: 3 1 0 Sequencer Complete DMA-inprog list: Sequencer Complete list: Sequencer DMA-Up and Complete list: scsi4: FIFO0 Free, LONGJMP == 0x80ff, SCB 0x0 SEQIMODE[0x3f] SEQINTSRC[0x0] DFCNTRL[0x0] DFSTATUS[0x89] SG_CACHE_SHADOW[0x2] SG_STATE[0x0] DFFSXFRCTL[0x0] SOFFCNT[0x1] MDFFSTAT[0x5] SHADDR = 0x00, SHCNT = 0x0 HADDR = 0x00, HCNT = 0x0 CCSGCTL[0x10] scsi4: FIFO1 Free, LONGJMP == 0x81d8, SCB 0x3 SEQIMODE[0x3f] SEQINTSRC[0x0] DFCNTRL[0x0] DFSTATUS[0x89] SG_CACHE_SHADOW[0x2] SG_STATE[0x0] DFFSXFRCTL[0x0] SOFFCNT[0x1] MDFFSTAT[0x5] SHADDR = 0x00, SHCNT = 0x0 HADDR = 0x00, HCNT = 0x0 CCSGCTL[0x10] LQIN: 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 scsi4: LQISTATE = 0x0, LQOSTATE = 0x0, OPTIONMODE = 0x52 scsi4: OS_SPACE_CNT = 0x20 MAXCMDCNT = 0x0 SIMODE0[0xc] CCSCBCTL[0x4] scsi4: REG0 == 0x3, SINDEX = 0x11d, DINDEX = 0xe1 scsi4: SCBPTR == 0x3, SCB_NEXT == 0x2, SCB_NEXT2 == 0x2 CDB 28 0 0 80 19 ac STACK: 0x13 0x0 0x0 0x0 0x0 0x0 0x0 0x0 <<<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>> DevQ(0:0:0): 0 waiting (scsi4:A:0): 80.000MB/s transfers (40.000MHz DT, 16bit) ===========================================

I believe you can buy support for the product for them, if you need it. Qemu might be a truely OSS solution. I personally have not used it in quite a long time, though, but I've heard it can be reasonable when used with the accelerator module. robert

Upgraded BackupPC (3.0.0) in the Testing Repository
by Johnny Hughes 01 Mar '07

01 Mar '07

There is an upgraded BackupPC in the testing repository. It is version 3.0.0, which was released in January. The setup differences between version 2.1.2 and this version is that some file directories have shifted locations: 1. /var/lib/backuppc/conf is now instead /etc/BackupPC/ 2. /var/lib/backuppc/log is now /var/log/BackupPC =============================== If you are upgrading ... you _CAN_NOT_ just copy your old config.pl config file into /etc/BackupPC can continue on ... you need to migrate in any changes that you made to original file to this config.pl file as there are updated options in the new file. How is the best way to do that ... you did save a copy of the original file prior to changing it ... right :P If not ... here is what I did: ----commands---- cd /tmp mkdir backuppc cd backuppc wget http://dev.centos.org/centos/4/testing/i386/RPMS/backuppc-2.1.2-3.c4.centos… rpm2cpio backuppc-2.1.2-3.c4.centos4.i386.rpm | cpio -idv ----end commands----- You should be in /tmp/backuppc and you should see all the files (extracted) from the original RPM in there ... inside the /tmp/backuppc/var/lib/backuppc/conf/ should be an original config.pl file. You can use that file to create a diff file that you can read to make changes to the new config.pl file. here is what I did prior to upgrade: ----commands---- cd /var/lib/backkuppc/ cp -a conf conf.bak cp -a logs logs.bak cd conf.bak cp /tmp/backuppc/var/lib/backuppc/conf/config.pl config.pl.orig diff config.pl.orig config.pl > config.pl.diff ----end commands---- Now you are ready to upgrade ... you will need to enable the testing repo to do the upgrade (or download the files manually and install manually via RPM). How to do the upgrade via yum: Put the testing repo file into /etc/yum.repos.d/ : http://dev.centos.org/centos/4/CentOS-Testing.repo (the file is disabled by default) Once you have the file in place, use this command: ----commands---- yum --enablerepo=c4-testing upgrade backuppc perl-Compress-Zlib perl-File-RsyncP perl-Time-modules perl-XML-RSS ----end commands---- (that command in all on one line if it wraps in your mail client) You can use that diff file from above to manually add new changes to the /etc/BackupPC/config.pl file after upgrade. Also after upgrade, you can move all the files in /var/lib/backuppc/log/ to /var/log/BackupPC/ Once everything is configured ... restart backuppc and httpd Once everything is working, you can get rid of the following directories in "/var/lib/backuppc/" ... conf, conf.bak, log, log.bak If you are installing new, replace "upgrade" with "install" in the above yum command ... and see the README.centos file in /usr/share/doc/backuppc-3.0.0/ after install Here is the original announcement, which also has good info: http://lists.centos.org/pipermail/centos-devel/2006-April/002216.html Thanks, Johnny Hughes

Add RAID after install in one disk
by Mário Gamito 01 Mar '07

01 Mar '07

Hi, I had this hard time installing a server with RAID 1 by software. I always got an error from GRUB and no booting. So, i've installed CentOS 4.4 normally in only one disk. Question is: is it possible now to make a RAID 1 by software with the other disk ? If so, how ? I'm completely lost here. Any help would be appreciated. Warm Regards, Mário Gamito

Hi all, I know it's a dummy question, but ¿where is the gnome's quick launcher for OpenOffice.org suite? I search in several repos under their common name (ooqstart-gnome) without any result. ¿Where is it or what is the package's name? Thanks.

01 Mar '07

I am trying to get XDMCP working over SSH on CentOS 4.4 from a windoze box running Cygwin/Putty I have set Enable=true in /etc/X11/gdm/gdm.conf restarted the X server, logged in with Putty and X11 forwarding enabled. I then try to start the Xserver with the following commands # gdmXnestchooser localhost or # Xnest :1 -query localhost Both commands will successfully display a X window and show the X mouse pointer but not the chooser. Can anyone tell me what I am doing wrong? Thanks Dean
