salvager -parallel all8
no space between all and the numeral; replace the numeral with the
actual number of partitions to salvage in parallel.=20
you will be much happier.

I'm monitoring /usr/afs/logs/SalvageLog.0 to get an idea on progress..

Also do you have your bos server automatically running restart on a
weekly basis? I'm looking to minimize downtime. Would splitting up my
/vicepa to smaller
Partitions speed up the salvage process?
on a clean shutdown i hope you aren't salvaging.
