Hello,
I encountered the following issue on my FFS1 data filesystem. It didn't
suffer any unclean shutdown since at least last fsck(8) run (yes, it is
already clean), nonetheless fsck(8) reports incorrect link count of one of
the directories. It didn't complain before and the filesystem never
experienced any unclean shutdown when being written to.
# /sbin/fsck -nf /dev/rsd5a
** /dev/rsd5a (NO WRITE)
** File system is already clean

ADJUST? no
** Phase 5 - Check Cyl groups
926687 files, 479312280 used, 1183201 free (91681 frags, 136440 blocks, 0.0%
fragmentation)
# /bin/ls -ldi /mnt/photo/
7362198 drwxr-xr-x 574 1005 1005 19968 Jul 23 16:47 /mnt/photo
The /mnt/photo/ directory (inode 7362198) currently lists 570
subdirectories as fsck(8) suggests (572-2) and there shouldn't be any
extraordinary hardlinks to that directory. I didn't delete any
subdirectory from that directory.
The filesystem is FFS1, the device is a regular 512 bytes/sector external
USB hard drive. Write operation are usually done while this filesystem is
mounted with -o softdep.
The filesystem was handled by this snapshot:
OpenBSD 5.3 (GENERIC.MP) #53: Fri Mar 1 09:34:37 MST 2013
dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC.MP
I also verified filesystem integrity with recent ramdisk kernels, with the
same result.
Is there any explanation for the two additional links in the reference
count? Should I be worried that I've lost two subdirectories somehow?
(I can't verify that.)
Thanks for any hints.
Regards,
David
