PROBLEM: log abort over RAID5
Several people already reported this at linux-kernel and
elsewhere with no answers, I thought perhaps this would be a more
adequate forum...
[1.] One line summary of the problem:
After I/O, journal is aborted and filesystems made read-only.
[2.] Full description of the problem/report:
One can't anymore write to the affected file systems. Upon
investigation, ext3fs journal was aborted and affected filesystems are
remounted read-only. Reboot prompts for fsck to be run manually, with
fixes taking several prompts and minutes.
[3.] Keywords (i.e., modules, networking, kernel):
File systems, I/O, RAID, LVM, kernel.
[4.] Kernel version (from /proc/version):
Couldn't find /proc/version, uname -a gives:
Linux mercurio 2.6.2-1-686-smp #1 SMP Sat Feb 7 15:27:45 EST 2004 i686
GNU/Linux
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
N/A
[6.] A small shell script or example program which triggers the
problem (if possible)

[X.] Other notes, patches, fixes, workarounds:
No known patch or fix, not enough knowledge or skill, sorry...
Have seen various reports by Googling around, from 2.5
something up to 2.6.3.

Check if the hard disk has bad blocks. # badblocks -b <ext3blocksize> <ext3device> If you have errors here, than ask again what to do in this list - I don't know how to recover from errors like bad blocks in the journal ;-) Assuming badblocks didn't report any errors, continue: 2. Umount the filesystem 3. Run e2fsck If that fails, report it here and don't continue ;-) 4. Try to remount the filesystem as ext3. If that works, you should be done. 5. If that doesn't work then: Report the error messages here. You may continue or wait for answers ... 6. disable usage of journal: tune2fs -O ^has_journal <ext3device> 7. mount the file system as ext2 and update /etc/fstab according to that. Regards, Bodo

It's just not possible to diagnose _why_ it went bad from the data here. It could be a disk or driver fault; bad memory, overheating CPU, configuration error, anything. Is there a repeating pattern to the problems? --Stephen
