Server in question is a Proliant DL360G5, dual Xeon 3.2GHz and 3GB of
RAM. It has a fibre connection to a SAN housing a terabyte NSS
pool/volume. The volume is 80% full.

I'm getting errors on this volume, to wit:

11-06-2007 8:46:31 am: COMN-3.25-178
Severity = 5 Locus = 3 Class = 0
NSS-2.70-5009: Pool NWC1FS1/NWC1P1 had an error
(20012(beastTree.c[510])) at block 7328906(file block -7328906)(ZID 1).

The errors always references the same file block. They appear to date
from about two weeks ago when our the remote site housing our SAN
suffered a power outage.

Any guesses how long it will take to rebuild an NSS pool of this size?
