This made me remember a problem I see on a -current machine
(rebuild yesterday):
THE FOLLOWING FILE SYSTEM HAD AN UNEXPECTED INCONSISTENCY:
ufs: /dev/da0s1f (/var)
Automatic file system check failed . . . help!
Enter full pathname of shell or RETURN for /bin/sh:
# fsck -y /var
** /dev/da0s1f
** Last Mounted on /var
** Phase 1 - Check Blocks and Sizes
PARTIALLY TRUNCATED INODE I=31753
UNEXPECTED SOFT UPDATE INCONSISTENCY
INCORRECT BLOCK COUNT I=39698 (1904 should be 1808)
CORRECT? yes
PARTIALLY TRUNCATED INODE I=87341
UNEXPECTED SOFT UPDATE INCONSISTENCY
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups
FREE BLK COUNT(S) WRONG IN SUPERBLK
SALVAGE? yes
SUMMARY INFORMATION BAD
SALVAGE? yes
