[SunHELP] FS crashed

[Robo]

Hi

The first alternate superblock is always 32 so if you
substitute 32 for the # in the fsck command bellow and
put the disk on the end you may get your file system
back. The other thing to look at is there is an incantation
of newfs (I think - it may be the underlying raw command
which escapes me for the moment) which does a 'dry run'
of the file system creation - one of the superblocks
from this may work if the above doesn't...

Good Luck -- you may need it

Hi Gurus,

I have a crashed volume in a Solaris 2.6 environment, when I use fsck to
check it I have the following message:

** /dev/dsk/c2t0d5s6
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).


Could anyone please help me????

Thanks!!!!!

Srgio
