filesystem corruption with bad super block....

2007-12-25 2:56:00

All,

When I try fsck on a filesystem I get the below:

# fsck /dev/rdsk/c1t1d0s7
** /dev/rdsk/c1t1d0s7
BAD SUPER BLOCK: MAGIC NUMBER WRONG
USE AN ALTERNATE SUPER-BLOCK TO SUPPLY NEEDED INFORMATION;
eg. fsck [-F ufs] -o b=# [special ...]
where # is the alternate super block. SEE fsck_ufs(1M).

I then tried to use the alternate super block:

# fsck -F ufs -o b=32,f /dev/rdsk/c1t1d0s7
Alternate super block location: 32.
** /dev/rdsk/c1t1d0s7
BAD SUPER BLOCK: MAGIC NUMBER WRONG
USE AN ALTERNATE SUPER-BLOCK TO SUPPLY NEEDED INFORMATION;
eg. fsck [-F ufs] -o b=# [special ...]
where # is the alternate super block. SEE fsck_ufs(1M).
#

ANY ideas at all to get fsck to recognise this filesystem would be greatly
appreciated.

Cheers
Barry.
