First of all WD was not going to send us a new disk unless we sent the
old one in first -- the disks are not in hot swap bays, so I had
'remove' the bad disk from the RAID sets and shut down the machine to
remove it.

Second, we had a couple of power failures (yes, we have a UPS, but that
is only good enough for a graceful shutdown, not for an extended power

The machine was only shutdown because we *had* to shut it down.

The server is not a 'critical' server, in the sense that it has to have
near 100% uptime.  It is not public facing server in that sense.
