Hi,

   A 2nd reply to this same msg:

   Softupdates: No   SMP: No

   Anyways, just for grins, I 'umount'ed the 3 file systems I have
on the ccd (they went down cleanly). Then I fsck'd them. The 1st
two went fine. The 3rd gave:

FreeBSD# umount /snap
FreeBSD# fsck -y /dev/ccd0a
** /dev/rccd0a
** Last Mounted on /snap
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
LINK COUNT FILE I=146063  OWNER=root MODE=100444
SIZE=1771 MTIME=Oct 30 08:00 1998  COUNT 2 SHOULD BE 1
ADJUST? yes

LINK COUNT FILE I=146065  OWNER=root MODE=100444
SIZE=2311 MTIME=Oct 30 08:00 1998  COUNT 2 SHOULD BE 1
ADJUST? yes

..... About 50 more of these deleted ...

LINK COUNT FILE I=251568  OWNER=root MODE=100444
SIZE=1461 MTIME=Oct 30 08:00 1998  COUNT 2 SHOULD BE 1
ADJUST? yes

LINK COUNT FILE I=257185  OWNER=root MODE=100444
SIZE=3727 MTIME=Oct 30 07:58 1998  COUNT 2 SHOULD BE 1
ADJUST? yes

** Phase 5 - Check Cyl groups
1628 files, 32592 used, 1045183 free (4143 frags, 130130 blocks, 0.4% fragmentation)

***** FILE SYSTEM WAS MODIFIED *****
FreeBSD#    


   So, this make me wonder if we're really getting all the data
to disk properly (and this from a clean umount).

   Comments, Critiques, and even stupid user remarks are welcome.

Thanks!
John
