Package: e2fsprogs
Version: 1.37-2sarge1

Greetings,

I'm checking an ext3 file system on a ~240 GiB RAID-1 array (two "250
GB" drives, df reports 240362560 1K-blocks), and e2fsck segfaults.

Today it segfaulted while I wasn't there, the last message it printed
was: "i_fsize for inode xxxxx (...) is 234848, should be zero. Clear?"
(Pass 4?) Last night it segfaulted after going back for at least a Pass
1b to resolve a bunch of duplicate blocks; I'm not sure whether it
entered further passes.

The command line is:

e2fsck -y -C 0 /dev/md0

Today I ran it a third time under gdb, it got to about 93% and then in
Pass 4, after a handful of non-zero i_file_acls, bad modes and an
illegal FIFO, it segfaulted, the last messages were:

Inode 2919156 ref count is 90, should be 1.  Fix? yes

i_file_acl for inode 5350463 (...) is 3961695421, should be zero.
Clear? yes

i_faddr for inode 5350463 (...) is 2987423426, should be zero.
Clear? yes

i_frag for inode 5350463 (...) is 51, should be zero.
Clear? yes

i_fsize for inode 5350463 (...) is 214, should be zero.
Clear? yes

Previous frame inner to this frame (corrupt stack?)

This is /home on a production server (but with a backup), so I'm not too
interested in taking it down for another hour and a half for testing --
though if/when it crashes again, I'll give it another try.  Right now
it's up and running with the errors. :-(

Also, we just migrated from an 80 GB RAID-5 array to this array; this is
on an ABIT BP6 HPT 366 controller (I know, bad, bad, bad! but we don't
have the money for a new server).  The old array on the same controller
had a MTBF around 40 days before it crashed the machine, the new array
MTBF was a few hours, so we upgraded to the RU BIOS and it hasn't
crashed since...

Thanks,

-Adam

Changes: 
 e2fsprogs (1.38-2) unstable; urgency=low
 .
   * Previous NMU acknowledged (Closes: #317862, #320389)
   * Fix debugfs's set_inode_fields command so it doesn't silently fail
     when setting certain inode fields.
   * Fix e2fsck from segfaulting on disconnected inodes that contain one or
     more extended attributes.  (Closes: #316736, #318463)
   * Allow mke2fs and tune2fs to take fractional percentages to the -m
     option in mke2fs and tune2fs.  (Closes: #80205)
   * Fix a compile_et bug which miscount the number of error messages if
     continuations are used in the .et file, and fix compatibility problems
     with MIT Kerberos 1.4
   * Add extra sanity checks to protect users from unusual cirucmstances
     where /etc/mtab may not be sane, by checking to see if the device is
     reported busy (works on Linux 2.6) kernels.  (Closes: #319002)
   * Fix use-after-free bug in e2fsck when finishing up the use of the
     e2fsck context structure.
