Hi,
I have an issue with my /var partition, the others are allright.
When I boot into single user, fsck_ufs /var gives no errors, both
mounted and umounted.
However, if I boot into multi user, fsck_ufs gives error messages,
allthough at boot time the file system is clean. The messages vary:
run 1:
-------
** /dev/ad0s1e (NO WRITE)
** Last Mounted on /var
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
UNREF FILE I=4241 OWNER=mysql MODE=100600
SIZE=2349 MTIME=Oct 4 11:38 2004
CLEAR? no
UNREF FILE I=4257 OWNER=mysql MODE=100600
SIZE=0 MTIME=Oct 4 11:37 2004
CLEAR? no
UNREF FILE I=4272 OWNER=mysql MODE=100600
SIZE=0 MTIME=Oct 4 11:37 2004
CLEAR? no
** Phase 5 - Check Cyl groups
2443 files, 39110 used, 25297 free (1481 frags, 2977 blocks, 2.3% fragmentation)

run 2:
-------

** Last Mounted on /var
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
UNREF FILE I=4241 OWNER=mysql MODE=100600

Inode 4241 changed time between run 2 and run 3. The mysql user comes
from the databases/mysql40-{client,server} ports. It probably hits the
bad spot. But it continues to give errors if I turn mysql off :
** /dev/ad0s1e (NO WRITE)
** Last Mounted on /var
** Phase 1 - Check Blocks and Sizes
INCORRECT BLOCK COUNT I=39 (4 should be 0)
CORRECT? no
** 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? no
SUMMARY INFORMATION BAD
SALVAGE? no
BLK(S) MISSING IN BIT MAPS
SALVAGE? no
2439 files, 39163 used, 25243 free (1483 frags, 2970 blocks, 2.3% fragmentation)

And sometimes /var seems to be ok.
I don't get ATA_READ / ATA_WRITE errors (yet).
Does this mean my harddisk is somehow dying? It has been running
continously for 2-3 years, and in use since September 2000.
I went to the notebook service centre of the university this afternoon.
The guy there said the disk was allright. He performed a surface and
SMART scan from a CDROM. On the other hand, I read in the questions@
archive that surface scans are useless on FreeBSD systems. The NSC guy
recommended to reinstall the software, but that seems pointless to me.
