how to find cause of disappearing files
by Bob Lewkowitz 11 Feb '06

11 Feb '06

Hello....here is an odd problem for me. I have a Centos 3 server which has software installed that creates its pid files in the /tmp directory. I am not sure which script on the server is being run that completely clears the /tmp directory except for directories starting with periods. Can you guys think of a way for me to monitor these pid files and immediately log which process deleted these files as soon as it happens? thx...Bob.

SCSI RAID monitoring
by Joshua Baker-LePain 11 Feb '06

11 Feb '06

I'm looking to buy some new high-reliability servers (mail server, cluster head node). I'll be doing a hardware RAID1 mirror w/ a hot spare, and I'm trying to decide between SCSI and SATA (albeit SATA w/ WD Raptor drives, so the price difference isn't as big as it would seem at first). I'm very familiar with 3ware's monitoring tools for their SATA RAID cards, and they work very well. What monitoring tools are out there for SCSI RAID cards? For that matter, what are the preferred SCSI RAID cards supported by centos 3 and/or 4? LSI MegaRAID is the one I'm leaning towards, but I'm open to suggestions. Thanks. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University

I appear to be attacking others
by James Pifer 11 Feb '06

11 Feb '06

It looks like my CentOS 4.2 box is attacking other people with some type of ftp attack. I got an email from somebody saying they were being attacked by my IP address. Further investigation /var/log/messages shows a whole bunch of sshd attacks on me, none of which appear successful. I'm running ethereal right now and I can see that my system is doing some kind of ftp attacks on others. I've think I've stopped the outgoing attacks at my firewall, but how do I proceed from here? Thanks, James

4.2 install w/250GB raid arrays won't boot
by rado 11 Feb '06

11 Feb '06

hi! raid 1 arrays: I already have 2 systems running this same raid1 config. 1 sys has 2 120 gb 1 sys has 1 120gb and 1 200gb but matching the raid partitions this system here that is giving me fits right now has 1 250gb and 1 200gb. I tried it w/a new 250 gb for the 2nd drive but the same results. Will not boot. in druid, when I am config. the raid arrays, I always create the boot partitions in hda1 and hdc1 and make them primary...maybe I am doing wrong by giving them 200mb instead of 100mb but I do it in the other 2 raided systems I run and no probs. I then create the sys partitions: hda2 and hdc2 lastly, the swaps as hda3 and hdc3 ........................... grub: here's what I did/do and here's the results: linux rescue chroot /mnt/sysimage /sbin/grub-install /dev/hda ...the complaint/result: /dev/md0 does not have any corresponding drive I have tried: /sbin/grub-install /dev/hda (as a stab in the dark) it gives the same result /sbin/grub-install /dev/hdc also produces the same result I have done the following: dropped to grub # grub grub> root (hd0,0) result: Filesystem type is ext2fs, partition type 0xfd grub> setup (hd0,0) result: Checking if: "/boot/grub/stage1" exists ....no "/grub/stage1" exists...yes "/grub/stage2" exists...yes "/grub/e2fs_stage1_5" exists...yes Running: "embed /grub/e2fs_stage1_5 (hd0,0)"...failed(this is not fatal) "embed /grub/e2fs_stage1_5 (hd0,0)"...failed(this is not fatal) "install /grub/stage1 (hd0,0) /grub/stage2 p /grub/grub.conf"...suceeded done I messed w/cmos...oh, enable/disable S.M.A.R.T. Drive....bypassing cd- rom drive...so hd0 be the first boot...nothing changes...just "DISK BOOT FAILURE" etc thx! John Rise

A safe starting point is "yum clean all", but sounds more like your mirror list is pointing to a server that is not available, has dropped CentOS, or changed the path. Check all the servers in your config files. I like to use a local mirrorlist and/or hand-configure nearby and fast mirrors with baseurl=... in the /etc/yum.repos.d/*.repo files. If you want more detailed help you need to supply more info on your configuration.

question on software raid-1
by Jerry Geis 11 Feb '06

11 Feb '06

I have a system that is RAID -1 configured as /dev/md0 is /dev/hda1 /dev/hdb1 /dev/md1 is /dev/hdb3 /dev/hdb3 it seems as though /dev/hda has failed.... I have another disk (identical model) that I can replace hda with. I know about the commands fdisk to repartion and raidhotadd /dev/md0 /dev/hda1 and raidhotadd /dev/md1 /dev/hda3 (to be ran after the system boots). BUT... how do I now get the system to boot since hda is not there to boot... I can certainly execute the fdisk and raidhotadd after it boots... How do I get it to boot. The hardware is a D865 intel motherboard with 2 seagate 120G drives. Thanks, Jerry

Unable to update
by Wright, Paul 10 Feb '06

10 Feb '06

Greetings! I am running a Centos-4 box and since January 17, I have been unable to update. If I run 'yum update' from the command line, I get error messages about being unable to locate a mirror while trying to obtain primary.xml.gz. If I run up2date from the GUI, it times out as it is trying to access the update file for firefox. Other than the problem with updates, this box doesn't seem to have any trouble accessing Web sites and there is not a proxy server in use on our network. Another box on my network that is running Centos-3 does not appear to be having the same problem. I would appreciate any hints on where to start troubleshooting this problem. Paul Paul M. Wright, Jr. Senior Systems Engineer Northwest Fire District 520-260-7520 cellular 520-887-1010 office 520-887-1034 fax pwright(a)northwestfire.org
