one of the hard drives on moly has died. this was spotted by cymru's staff
and confirmed when smartd was installed (#29709).
i have done some research on the machine to figure out what's up, and
wrote the following reply to Cymru's people:

I've created some documentation on the hardware RAID stuff here:
https://help.torproject.org/tsa/howto/raid/
we're at the waiting step now - we'll see if Cymru can do the replacement
and when. i'm still not quite certain we can just hotswap the drive, but
I'm hoping we can.
