drbd on CentOS 5
by Kanwar Ranbir Sandhu 01 Jan '08

01 Jan '08

Hi All, Is the centosplus kernel still needed for drbd support? I noticed that if I do a 'yum update kmod-drbd', yum gives me an error because it wants to install the "normal" CentOS kernel, but can't since I have it excluded. I do see kmod-drbd in the centosplus repo though. Regards, Ranbir -- Kanwar Ranbir Sandhu Linux 2.6.22.9-61.fc6 i686 GNU/Linux 15:12:04 up 21 days, 13:43, 1 user, load average: 0.72, 0.85, 0.94

Centos 5.1, mythtv, saa7134_dvb?
by Mogens Kjaer 01 Jan '08

01 Jan '08

I'm trying to set up my Centos 5.1 box at home to run mythtv. The DVB-T card requires saa7134 and saa7134_dvb. These are not in the Centos kernels. Centosplus has saa7134, but not saa7134_dvb. Do I have to compile the kernel myself, or is there a trick?

1680x1050 Monitor
by centos＠911networks.com 01 Jan '08

01 Jan '08

Hi, I just got a new Samsung 226bw 22" wide monitor to replace my previous one. I also have a nvidia 8600gts video card. I can set interactively [through the nvidia-settings utility] the 1680 by 1050 resolution. I have saved the settings in the xorg.conf, but I can't keep it after a restart of X or a reboot. When I restart X, the login is at: 1680 by 1050, then it switches to 1280 by 1024. Here are the video sections from my xorg.conf Any suggestion with what's wrong? Section "Module" Load "glx" EndSection Section "Device" Identifier "Videocard0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce 8600 GTS" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "1680x1050 +0+0" SubSection "Display" Depth 24 EndSubSection EndSection -- Thanks http://www.911networks.com When the network has to work

ISO burning challenge -- pilgrims progress
by Robert Moskowitz 31 Dec '07

31 Dec '07

First the Storix drive works just fine under DSL 4.2.1 on my Libretto. So the drive is fine, the media is fine. And cdrecord on DSL reports the media to be Manuf. index: 27 Manufacturee: Prodisc Technology Inc. I have all of ONE system with Centos 4 on it. A Trixbox 2.2; I added cdrecord and found that I could burn the iso image ONLY by including the -force option to get around the "cdrecord: Cannot get disk type" error. So I moved back to the Centos 5 system. I had to add the speed=4 (when the unit supports speed=8) along with the -force to get it to burn a iso image (btw, timeout=100 does nothing. The failure is in a few seconds, adding to the timeout changes nothing). There are a number of timing errors on the Centos 5 system. Even the Centos 4 system had a SCSI error (0x7000). I did find ONE mention of "cdrecord: Cannot get disk type": http://crashrecovery.org/oss-dvd/Changelog.html but that is dated 2/2/06. One would think it is fixed in Centos 5..... I have NOT gotten the HP CDRW working yet, that is the one I want to leave on the server, as the Storix is my traveling drive. More work. Any pointers gladly taken! I REALLY want to move my CD processes to Centos. I want a GUI interface and want to rip and burn music CDs as well.....

Yum breaks after updating to CentOS 4.6
by Devraj Mukherjee 31 Dec '07

Hi everyone, Yum on one my CentOS systems has decided to stop functioning after an upgrade to CentOS 4.6. It's complaining about errors with Python-SQLite packages? Any ideas anyone? Here is what happens.

Help with full and incremental dumps
by Scott Ehrlich 31 Dec '07

31 Dec '07

I have an Overland Arcvault 12 library with a full LTO3 magazine of 400/800 GB tapes. It is connected directly to the fileserver via a SCSI card/cable. The two main directories I want to back up are /var/log, which is on one filesystem, and /home, which is on another. There are _currently_ no databases to worry about, but there may be active users logged in and active jobs running. We'll just take our chances with what can be backed up. I've successfully run dump/restore to an external USB 1 TB hard drive as our backup device until the tape library arrived. Now, finding the appropriate dump and restore commands to throw into a script is the fun part. The first time will obviously produce a full backup of said directories to back up. Subsequent ones will be incremental. What should my dump lines look like for both full and subsequent incrementals? And, to test the backup and in case I need to retrieve a file, what should a respective restore line look like? Thanks much. Scott

MOre on buring ISOs
by Robert Moskowitz 31 Dec '07

31 Dec '07

So right now I have installed k3b on this notebook. I am using my Storix DVD/CDRW usb drive. I can read cds with it. Cannot burn CDs. First k3b suggests slowing down (from 8x to 4x). Then use TAO. Then it gave up. So I try cdrecord directly. -checkdrive finds some interesting things. Got to close the drive manually; cdrecord says it can't. then try a cdrecord -v dev=dev/scd0 sample.iso and if fails: cdrecord: No write mode specified. cdrecord: Asuming -tao mode. cdrecord: Future versions of cdrecord may have different drive dependent defaults. cdrecord: Continuing in 5 seconds...

Can't connect to torrent tracker
by William L. Maltby 30 Dec '07

30 Dec '07

Well, yesterday my 5.1 and 4.6 systems could connect to torrent.centos.org OK. Today neither system can connect. I can ping, but that's all. No changes were made to the firewall during this time. Any tips on debugging this? I successfully http downloaded all the ISO images from various mirrors this morning, so I think my net and firewall are OK. TIA -- Bill
