Title:
Repetitive massive filesystem corruption
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Lucid:
Won't Fix
Bug description:
This problem has been ongoing since Kubuntu 9.10 but I was unable to
take the time to properly diagnose the error during that product cycle
(and I hoped a newer kernel would solve the problem). I can also
report that the problem is reproducible in openSUSE 11.2, so this is
possibly even a mainline kernel problem.
In short, I experience massive filesystem corruption on ext4. In 9.10
I could also reproduce the corruption using ext3, but I have not yet
had a chance to test ext3 under 10.04. I was also able to reproduce
the problem on 9.10 by mounting from Live CD and creating a filesystem
on an internal hard drive. The symptions on 10.04 are so far
identical, but I haven't yet been able to perform all the testing I
did under 9.10. I have attached an example fsck log from current
10.04.
Corruption is sometimes detected when booting; other times the
filesystem switches to read-only while the system is running. The
latter is what happened on the first boot of my current installation
of 10.04. A subsequent boot left me able to perform all system
updates. Then after rebooting the system the filesystem switched to
read-only within a few minutes of logging in. The only cure for the
read-only filesystem is to boot from CD and run e2fsck manually.
Since October, I have performed some hardware troubleshooting (many, many
times):
1) Hitachi Drive Fitness Test, which always reports Disposition Code 00: no
errors;
2) badblocks: always reports no bad blocks found, regardless of the
blocksize, etc.
SMART reports the drive status as good, with no serious errors
reported. Memtest 86+ says the RAM is good. The machine runs
flawlessly under 9.04 or earlier using ext3, and NTFS produces no
similar corruption under either Windows XP or Windows 7.
As I enter this bug report, I've been running with no errors for the
last 30 minutes, and there's no way to predict if/when corruption will
reappear. As a further troubleshooting step I have turned write
caching off using the Hitachi Feature Tool; I previously did this
using hdparm.conf, but IMHO write caching shouldn't be blamed for any
corruption during normal system operation, but only after an unclean
shutdown.
I should add that I've seen bug reports with quite similar symptoms on
64-bit systems, but I should emphasize that I'm running 32-bit on this
system, with an ICH4-M controller. The corruption problem hasn't
surfaced on any of my either systems, which include both Intel and VIA
controllers.
