SCSI? Probleme

Hallo,

seit gestern beobachte ich gewisse Ungrereimtheiten, die ich mir
nicht ganz erklären kann. Es fing an mit:

kernel: da0 at ahc0 bus 0 target 1 lun 0
kernel: da0: <IBM DNES-309170W SAH0> Fixed Direct Access SCSI-3 device
kernel: da0: 80.000MB/s transfers (40.000MHz, offset 30, 16bit), Tagged
Queueing Enabled
kernel: da0: 8748MB (17916240 512 byte sectors: 255H 63S/T 1115C)

0 0 20 0 0
kernel: (da0:ahc0:0:1:0): CAM Status: SCSI Status Error
kernel: (da0:ahc0:0:1:0): SCSI Status: Check Condition

Die Zeilen ab dem 2. READ(16) wiederholen sich dann unzählige male.
Nach einem Neustart mußte ich ein manuelles fsck durchführen:

fsck: /dev/da0s1g: UNREF FILE I=188901 OWNER=pgsql MODE=100600
fsck: /dev/da0s1g: SIZE=6 MTIME=Aug 13 07:42 2003 (CLEARED)
fsck: /dev/da0s1g: Reclaimed: 0 directories, 3 files, 2 fragments
fsck: /dev/da0s1g: 10114 files, 1522737 used, 647867 free (10243 frags,
79703 blocks, 0.5% fragmentation)
fsck: /dev/da0s1e: Reclaimed: 0 directories, 30 files, 131 fragments
fsck: /dev/da0s1e: 133 files, 27146 used, 99562 free (58 frags, 12438
blocks, 0.0% fragmentation)
fsck: /dev/da0s1f: UNKNOWN FILE TYPE I=2752
fsck: /dev/da0s1f: UNEXPECTED SOFT UPDATE INCONSISTENCY; RUN fsck
MANUALLY.kernel: handle_workitem_freeblocks: block count

Danach "lief" wieder alles normal, zumindes soweit ich es beurteilen konnte.

Gerade eben tauchte dann folgendes auf:

kernel: handle_workitem_freeblocks: block count
kernel: handle_workitem_freeblocks: block count
kernel: free inode /home/48972 had -765908 blocks
kernel: free inode /home/48973 had -745316 blocks
kernel: handle_workitem_freeblocks: block count
last message repeated 3 times
kernel: free inode /home/48961 had -745316 blocks
kernel: free inode /home/48962 had -749536 blocks
kernel: handle_workitem_freeblocks: block count
last message repeated 2 times
kernel: free inode /home/48960 had -765908 blocks
kernel: free inode /home/48964 had -765908 blocks
kernel: free inode /home/48965 had -745316 blocks
kernel: free inode /home/48968 had -765908 blocks
kernel: free inode /home/48969 had -745316 blocks

Seit dem gibt df nur noch unrealistische Werte aus:

Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/da0s1a 253678 83182 150202 36% /
devfs 1 1 0 100% /dev
/dev/da0s1g 4341212 -88540 4082456 -2% /home
/dev/da0s1e 253678 54294 179090 23% /tmp
/dev/da0s1f 2971278 2257758 475818 83% /usr
/dev/da0s1d 253678 37722 195662 16% /var
fdescfs 1 1 0 100% /dev/fd

# du -s /home
3308680 /home

Kann mir einer erklären, was das zu bedeuten hat?
Geht meine Hardware gerade kaputt? Die Festplatte
sollte es eigentlich nicht sein, oder?

# camcontrol defects 0:1:0 -f phys -G
Got 0 defects.

Dank schon mal

Sebastian
