     If I try to run an fsck I get the following:
    altair# fsck -F ufs -n b=32 /dev/dsk/c2t0d0s6
    Can't stat b=32
    ** /dev/dsk/c2t0d0s6 (NO WRITE)
    BAD SUPER BLOCK: NUMBER OF DIRECTORIES OUT OF RANGE
    USE AN ALTERNATE SUPER-BLOCK TO SUPPLY NEEDED INFORMATION;
    eg. fsck [-F ufs] -o b=# [special ...]

    I have tried several superblocks with the same result. I use the newfs -Nv
    to get the superblocks.

    Thanks,
    Gus

     Hi all,
     I have a strange problem with a file system. It is a UFS file system,
    Solaris 8, with logging enabled. When I do a df I get this:
    /dev/dsk/c0t0d0s4 2053605 10114 1981883 1% /opt
    /dev/dsk/c0t0d0s7 22361943 635626 21502698 3% /sas
    /dev/dsk/c2t0d0s6 70574666 18446744060624891154 13154529382
    26401931016860% /sasdata
    The size of the third entry is correct at 70GB but the 'used' and 'avail'
    are way off. It was not always this way, the numbers for the /sasdata mount
    were right, this happened after a system crash. I can access all the data
    just fine but can't run an fsck on the system. It keeps asking for an
    alternate superblock, even though I have tried several different ones. Any
    idears??

    Thanks in advance,
    Gus Diaz
