超级快修复

Please try follow steps :

With the information that I have, it looks like you should be able to install an alternate superblock as follows:

Make sure that this fs is not mounted (it probably won't let you mount anyway)

1 - first find the alternate superblocks:

# newfs -N /dev/rdsk/c1t1d0s1

This will list the superblocks, with the first one being the default.  This is non-destructive.

2 - second, install the second superblock:

# fsck -F ufs -o b=[superblock number] /dev/rdsk/c1t1d0s1

3 - test the filesystem with:

# fsck -y /dev/rdsk/c1t1d0s1
