On one of my older P2 machines (running 3.9-stable), I seem to have a
very persistent fsck error: "BLK(S) MISSING IN BIT MAPS". Regardless
of whether or not I choose to salvage these, I keep getting the error
below.
The error occurs on an unmounted file system. After choosing to
salvage, seems to complete normally. Running it again yields the same
missing blocks message.
Expecting user error, I emptied the drive using dd, ran fdisk -i and
re-created the disklabel using the built-in editor (disklabel -E).
Even on a newly newfs'ed filesystem, the problem persists.
If anyone could shed some light on what is going wrong, I would
greatly appreciate it. Cluebats are equally welcome.
Output for fsck, fdisk, disklabel, /etc/fstab and dmesg are all
included below. If I should provide other info, please let me know.
Cheers,
Rogier
