LMFS emergency!

[bart@nynexst.com (Bart Burns)]

The LMFS for our file server started wierding out and finally bit the dust.

First i started getting messages like:

           File damaged, check words do not match
              Expected: 12526520651  1664   ...
              Actual:        0        0    ... 0
              .
              .
              .
           Cannot read record #o74132 of partition 4
           (fep1:>lmfs4.file.1)

All of these messages were from files in the same partition (fep1:>lmfs4.file.1),
so i ran the salvager (over the entire lmfs so it had a chance to fix what it could), 
but the salvager output (1,300 blocks worth) indicated to me that it wasn't able to do much.

The next day I had to shut down all our machines because the AC went down.

When I rebooted the file server (and tried to access lmfs) it
replied with a LMFS-BAD-PARTITION-LABEL error 

              Error: Bad label version on file partition fep0:>lmfs1.file.1

              (from stack frame of LMFS:ensure-lmfs-up)

        please note: a DIFFERENT partition (and a different disk drive) is gonzo here!


1. What can I do (short of reinitializing LMFS with new partitions (losing the old ones)) and
   hoping my latest complete backup tape (Exabyte 1.5 gigabyte) will restore?

2. Does this sound like a disk hardware failure?

help!

thanks,
Bart.
