hello all,
finally, after rtrying many times, the machine has booted normally.
Sorry for the noise (until the next problem!)
gerard
here is my original post:
on an ultra 10, slice 0 is always bad when booting. So i did many fsck_______________________________________________
to repair it. But what is strange is the follwing:
# fsck -y -F ufs /dev/rdsk/c0t0d0s0
** /dev/rdsk/c0t0d0s0
** Last Mounted on /mnt
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3a - Check Connectivity
** Phase 3b - Verify Shadows/ACLs
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cylinder Groups
71927 files, 2793224 used, 1330566 free (10582 frags, 164998 blocks,
0.3% fragmentation)
as you can see, there are no corrections, but:
# fsck -y -F ufs -o b=88800 /dev/rdsk/c0t0d0s0
Alternate super block location: 88800.
** /dev/rdsk/c0t0d0s0
** Last Mounted on
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3a - Check Connectivity
** Phase 3b - Verify Shadows/ACLs
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cylinder Groups
CORRECT BAD CG SUMMARIES? yes
CORRECTED SUMMARY FOR CG 0
FRAG BITMAP WRONG
FIX? yes
CORRECT GLOBAL SUMMARY
SALVAGE? yes
UPDATE STANDARD SUPERBLOCK? yes
71927 files, 2793224 used, 1334670 free (10582 frags, 165511 blocks,
0.3% fragmentation)
***** FILE SYSTEM WAS MODIFIED *****
and when i reboot, i got:
The / file system (/dev/rdsk/c0t0d0s0) is being checked.
/dev/rdsk/c0t0d0s0: BAD SUPERBLOCK AT BLOCK 16: BAD VALUES IN SUPER BLOCK
/dev/rdsk/c0t0d0s0: USE AN ALTERNATE SUPERBLOCK TO SUPPLY NEEDED
INFORMATION;
/dev/rdsk/c0t0d0s0: e.g. fsck [-F ufs] -o b=# [special ...]
/dev/rdsk/c0t0d0s0: where # is the alternate super block. SEE fsck_ufs(1M).
/dev/rdsk/c0t0d0s0: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
