It's usual for fsck to not want to run automatically if any inodes may
have to be cleared, or if any data loss might conceivably result from an
automated fsck.  It's annoying, but it errs on the safe side.

To keep this from happening, make sure that "logging" is one of the flags
present in the "Mount options" column of -every- read-write slice
specified in /etc/vfstab. That turns on the journalizing code, which will
keep your filesystems in good health upon power loss, assuming that you're
not actually in the middle of a disc write when the power goes flat.
