Hi. I woke up this morning to find a ton of waiting emails complaining that
some cron jobs on my system couldn't run because one of my filesystems (ext3
on software RAID 1) was suddenly mounted read-only. Always nice when you're
away from the server due to travel. ;^> I investigated in the logs and
found:
2007-08-02 04:02:25 kern.crit www kernel: EXT3-fs error (device md2): htree_dirblock_to_tree: bad entry in directory #3616894: rec_len is too small for name_len - offset=103576, inode=3619715, rec_len=12, name_len=132
2007-08-02 04:02:25 kern.err www kernel: Aborting journal on device md2.
2007-08-02 04:02:25 kern.crit www kernel: ext3_abort called.
2007-08-02 04:02:25 kern.crit www kernel: EXT3-fs error (device md2): ext3_journal_start_sb: Detected aborted journal
2007-08-02 04:02:25 kern.crit www kernel: Remounting filesystem read-only
I unmounted the filesystem and ran fsck, but though it detected that the
filesystem had errors, it didn't report any findings during the check:
fsck 1.35 (28-Feb-2004)
e2fsck 1.35 (28-Feb-2004)
/dev/md2: recovering journal
/dev/md2 contains a file system with errors, check forced.
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/md2: 200231/5248992 files (1.4% non-contiguous), 1563304/10492432 blocks
I remounted the filesystem and all *seems* to be okay now. I was curious
what "directory #3616894" (inode 3619715) was, so I did 'find / -inum
3619715 -exec ls -dioF {} \;', but the output showed that that was a
non-directory file created and last modified in 2004. How could this be?
And what would cause an error like the above? Am I out of the woods now, or
is there more checking of some kind that I should do to make sure this isn't
going to be happening again?
Thank you for your time!
