Thanks, I did indeed have console access so I followed this, with the
change that I sent a SIGTERM to nfsd and its sibling processes and
unmounted the data partitions (and disabled swap) before sending the
SIGTERM to init.

I was under the impression that you had to disable the raid with raidctl
but could not find a trace of that in the missing rc scripts so I let
it be and let poweroff handle the rest. The system made a 'thunk' sound
when it powered off which was unnerving -- I expected to hear the hdds
spin down a few seconds before the actual power cut. Maybe I should've
used 'halt' instead and cut power manually. But I guess it worked out
all right in the end.
