	Recently we had a bad electrical storm here and it nocked out one of our
	DN3500's.  When rebooting it attempts to run salvol and fails.  I have
	managed to boot the node over the network and to forcibly mount it's disk.
	I have dumped the contents of it's disk (using wbak) to another node and
	will invol and restore the files.  I expect this to remove the file system
	errors reported by salvol (can anyone confirm this?).
	 
	Also, does anyone know what if anything can be done about the following output
	from salvol (attached below).
	 
	 
	Starting second Pass...
	    Preparing file list...

	Internal Error: hash table for bad daddrs is full, too many MAB's or header erro
	rs.
	 
	RUN ABORTED

This is fixed in 10.3 salvol.  Look for it on the august patch tape, as well.

We lost a minimum of 3 gigs of disk to this one.  It may be related to crashes
of salvol that have cost us upwards of 30 gigs of disk space.

If someone from Apollo could elaborate about this bug, and explain what causes
it, I would be very grateful.
