kernel BUG at fs/reiserfs/prints.c:339! kernel 2.6.5

[Anthony R.]

Hi,

Using kernel version 2.6.5, Pentium 4 PC,
ReiserFS. While running slocate cron job, the
following errors showed up and the harddrive's
LED remained lit until a hard power cycle. I've been running
2.6.x kernels on this same hardware for months and never
saw this problem before until kernel 2.6.5. I realize it could be a
hardware problem but I want to report it here first.

Thank you.

[PATCH] ReiserFS I/O error Handling [was Re: kernel BUG at fs/reiserfs/prints.c:339! kernel 2.6.5]

[Jeff Mahoney]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1


It's most definately a hardware problem. It could be your disk, your
controller, or the cable connecting them, but somehow hdb1 started
getting I/O errors. One of them just happened to be in the journal area,
which ReiserFS doesn't handle well at the moment; it just panics, which
is what you saw.

I've got a patch in development that I just need to squeeze one last bug
out of that will allow ReiserFS to take write errors while writing to
the journal or flushing out from the journal to the disk more
gracefully. Rather than panicking, it remounts the filesystem read-only
and aborts existing transactions. The filesystem can then be umounted.

The last bug that I'm working out is a race at umount. It happens on
average 1/10 umounts, but it's still a bug.

I've posted my patches at
ftp://ftp.suse.com/pub/people/jeffm/reiserfs/kernel-v2.6/io-error/

Since this was developed on the SuSE kernel, Chris Mason's data logging
patches are also required. My xattr patches are required for context,
but if you don't have them applied, you can safely remove the xattr
portions of the patch.

FYI, I did an extensive HW test from the vendor and all tests passed.
So I'm not sure it's definitely a HW problem.

I will check out the patches though, thanks.
