trying to build driver for hpt374 raid controler
by Ulrik S. Kofod 20 Oct '05

20 Oct '05

I'm trying to build driver for hpt374 raid controler on a new installation of contOS 4.2 followin the instroctions in this thread http://www.centos.org/modules/newbb/viewtopic.php?viewmode=flat&order=DESC&… It says that I should run "yum install kernel-sourcecode" to get the files I need and it will create the path /usr/src/linux-2.6.9-5.0.3.EL which is needed. (guess it will be 2.6.9-22.EL in centOS 4.2) But the output from yum is this: [root@localhost hpt374]# yum install kernel-sourcecode Setting up Install Process Setting up repositories update 100% |=========================| 951 B 00:00 base 100% |=========================| 1.1 kB 00:00 addons 100% |=========================| 951 B 00:00 extras 100% |=========================| 1.1 kB 00:00 Reading repository metadata in from local files primary.xml.gz 100% |=========================| 9.8 kB 00:00 update : ################################################## 28/28 Added 12 new packages, deleted 0 old in 0.15 seconds Parsing package install arguments No Match for argument: kernel-sourcecode Nothing to do I tried using /usr/src/kernels/2.6.9-22.EL-i686 as KERNELDIR but that doesn't work. I tried "yum search /usr/src/linux" and "yum provides /usr/src/linux" with no result. I installed everything from the 4 centOS CD's but none of the scsi.h located on the system looks like the one I need as they don't define `SCSI_DISK0_MAJOR'. --- /root/hpt374/hpt.c:38:18: scsi.h: No such file or directory /root/hpt374/hpt.c: In function `get_bdev': /root/hpt374/hpt.c:60: error: `SCSI_DISK0_MAJOR' undeclared (first use in this function) /root/hpt374/hpt.c:60: error: (Each undeclared identifier is reported only once /root/hpt374/hpt.c:60: error: for each function it appears in.) /root/hpt374/hpt.c:60: error: initializer element is not constant /root/hpt374/hpt.c:60: error: (near initialization for `major[0]') --- What I'm I missing ? and SORRY if it is something obvious, this is the first time I'm trying to build a driver. best regards Ulrik

rebuilding mod_perl
by Shaun T. Erickson 20 Oct '05

20 Oct '05

If I say 'yum install mod_perl', on my CentOS-3 system, I get one built to work with the system's stock perl 5.8.0. I have built perl 5.8.7 and installed it in /usr/local/perl-5.8.7. How can I get the src rpm for mod_perl and build it against the newer perl? -- -ste

Re: [CentOS] Duplicated packages after yum crash

That's what worries me. I think yum probably crashed in the middle because of that. It's a x86_64 box here too. -- Giovanni P. Tirloni http://tirloni.blogspot.com

lvm over software raid error
by Jesse Waters 20 Oct '05

20 Oct '05

Came across a strange problem, I have a software raid1 with LV sitting on top. When I try to mirror an existing LV to a new LV with the tar command I get these error messages. mount /dev/vg00/base.centos /mnt/orig mount /dev/vg00/test /mnt/new cd /mnt/orig tar cf - ./|(cd /mnt/new; tar xf - ) ... File shrank by 406815 bytes; padding with zeros ... Read error at byte 49152, reading 10240 bytes: Input/output error Do I have data corruption? If I removed the snapshots, will the padding errors disappear?

RAID6 in production?
by Joshua Baker-LePain 20 Oct '05

20 Oct '05

Is anyone using RAID6 in production? In moving from hardware RAID on my dual 3ware 7500-8 based systems to md, I decided I'd like to go with RAID6 (since md is less tolerant of marginal drives than is 3ware). I did some benchmarking and was getting decent speeds with a 128KiB chunksize. So the next step was failure testing. First, I fired off memtest.sh as found at <http://people.redhat.com/dledford/memtest.html>. Then, I did 'mdadm /dev/md0 -f /dev/sdo1', and it started to rebuild as it should. I cranked up /proc/sys/dev/raid/speed_limit_min to 15000 so that it would reconstruct in a decent amount of time (the default of 1000 was leading to a 53 hour estimate for the recovery). But memtest.sh started kicking out errors (non-matching diffs). And then I got this: EXT3-fs error (device md0): ext3_journal_start_sb: Detected aborted journal Remounting filesystem read-only attempt to access beyond end of device md0: rw=0, want=28987566088, limit=4595422208 attempt to access beyond end of device md0: rw=0, want=28987566088, limit=4595422208 attempt to access beyond end of device md0: rw=0, want=28987566088, limit=4595422208 Needless to say it's not giving me that warm fuzzy feeling. The one caveat is that not all the members of my array were the same size -- one disk is 180GB while all the rest are 160GB. I'm going to test overnight with identically sized RAID members, but I also wanted to see if anyone else is using RAID6.

Can't install CentOS4
by Ajay Sharma 20 Oct '05

20 Oct '05

Hi everyone, My email server is running CentOS 3 and I can't upgrade it to CentOS 4 using the CD's. At first I thought it was the old Megaraid card (that's no longer supported), so I replaced that with a new card. I've tried ISO's from CentOS 4, 4.1 and now 4.2 which I've tested and booted in other machines. Just not this one. I've never had a problem like this before so I'm not sure what information you need to help me debug this. The server stops right after the line about detecting the AGP video. I have tried booting with noprobe and some other kernel options but nothing seems to work. Please let me know what else I can try to get it to boot.

Update 4.2 broke LVM
by Kevin Krieser 20 Oct '05

20 Oct '05

I upgrade using YUM my CentOS 4 system the other night. I was noticing that X wasn't coming up because of a gdk_thread issue (actually, the window manager wasn't starting. I cold get X to start from the command line). Surprised that it took 587MB of downloads, since I was current as of September 29th. When rebooting, I was forced to the login prompt, because my LVM group with my home directory couldn't be mounted. I'm not very familiar with LVM, I had only used it to make one consolidated directory for my 100 and 160GB hard drives. Though lvmdisplay could show the volume group, fsck and mount didn't like it. Oh, and the upgrade didn't fix the thread problem. Anyone have an idea whether it was just me having the LVM problem? I'm currently reinstalling CentOS4 (pre update 1) from CD. At least when running diskdruid, I could mount the LVM group. So, after my install, assuming it is still visible when booting from hard drive, I'll backup those drives before running YUM again. I'f the window manager doesn't start up again, I'll reformat on my next install.

4.1 being dropped from mirrors
by Karanbir Singh 20 Oct '05

20 Oct '05

Hi guys, Just to let everyone know that the CentOS 4.1 tree will be dropped from the mirrors shortly, since 4.2 has now been out for a week. If anyone has their yum config's hardwired to point at 4.1 - those config's will now stop working. The 4.1 repo's will be available at http://vault.centos.org/ once they are removed from http://mirror.centos.org/ ( and all external mirrors ). If you wish to stay with 4.1, keep in mind that updates and security fix's are no longer pushed out for 4.1, and therefore we recommend everyone moves to 4.2, if you have not already done so. - K -- Karanbir Singh : http://www.karan.org/ : 2522219@icq
