Something is writing a log
by Robert Moskowitz 30 Mar '07

30 Mar '07

I can just be sittting, doing nothing, and I hear the sound of my hardrive head moving. Just every so often. Like some process is writing a log. I have looked in /var/log and do see occational updates to acpi and messages, but that does not account for all the clicks. Is there somewhere else to look for logs? I would really like to know what process has something to remember.....

EXT3 fs error on RAID1 device
by Rasmus Back 29 Mar '07

29 Mar '07

Hi all. I have a Dell SC440 running Centos 4.4. It has two 500GB disks in a RAID1 array using linux software raid (md1 is / and md0 is /boot). Recently the root file system was remounted read-only for some reason. The logs don't show anything unusual, presumably the file system was read-only before anythng was logged. Running dmesg showed this error repeated many times: EXT3-fs error (device md1) in start_transaction: Journal has aborted Before rebooting the system I checked the raid array status with cat /proc/mdstat and mdadm. No errors were shown. When rebooting the system I let fsck do a check of the file systems. It reported several errors and I let it fix them. The thing that's bothering me is I can't find any reason for the EXT3 error. Nothing seems to be wrong with the array or the hardware. I also noticed a few worrying messages while booting up and shutting down. On boot-up mdamd complains that super-minor should only be declared once and then there's a message that File descriptor 21 is open. On shutdown there are messages that md0 and md1 are in immediate safe mode and that md1 is till in use. Is my system totally hosed or can I ignore these warnings? Thanks, Rasmus

Centos 3.6 or 3.7 CD isos x86_64
by Simpson, Kenneth 29 Mar '07

Hi - can someone please tell me where I can find Centos 3.6 or Centos 3.7 for x86_64? On the mirrors, there are directories labeled 3.6 and 3.7 but it's appears to be a lie. All the directories on the mirrors appear to be linked to 3.8 (and hence are mislabeled.) Thanks! -- Ken

Tape drive recommendations
by Mailing Lists 29 Mar '07

29 Mar '07

Hello all. I have 15 or so CentOS servers (now v4.4, I will upgrade them all to 5 when it comes out) and a few windows machines. I am looking to implement a network backup solution using Amanda. I will be backing up 200 gig or so to start, but that will grow. Does anyone have any recommendations on tape drives that will work "out of the box" with CentOS? Thanks, Joe

samba on centos with printer drivers
by Dave 29 Mar '07

29 Mar '07

Hello, I'm trying to set up a CentOS 4.4 print server. I've attached a Usb Hp Deskjet 5150 printer to the box, and printed a test page. This worked fine, using cups. I then went to the samba howto, classical printer section, and followed the section for uploading pointprint drivers to the box. My first problem came when i told the error dialog no, then didn't see a new driver button in the resulting dialog either on the general tab or sharing tab. I next tried again, this time i said yes to the driver installation, went through, had the apw find the drivers, on my CD, and it uploaded them no errors or so i thought. The process completed without errors, the rom and the hard disk moved, yet checking the samba box in the print$ share nothing has been added and i have global permissions set for this operation. I am doing this as a member of the printeradmins group and in smb.conf i did set: use client driver = no default devmode = yes for i have had an issue with a previous deskjet uploading drivers, that one actually gave me an error, and adding default devmode fixed it. My samba version is 3.0.10 if that helps. Any suggestions welcome. Thanks. Dave.

4.92 Beta questions.
by David Mackintosh 29 Mar '07

29 Mar '07

Installing through PXE, interactively from an NFS source. The installer is in text mode even though I have 512MB of memory. Two questions. 1. When installing package sets, I do not see an "Everything" option the way there was in 4.x. Should there be? I also don't recall being asked if I wanted Server/Workstation/Custom groupings. 2. When partitioning the disk, if I accidentally select "Use free space and create a default layout", the installer naturally cannot do anything. However it's failure mode is to report, then prompt for a reboot. Shouldn't it go back to the previous menu? I actually opened the second one as a minor bug, but then thought maybe I should ask about it first. -- /\oo/\ / /()\ \ David Mackintosh | dave(a)xdroop.com | http://www.xdroop.com
