After a 'shutdown -p now', it was about 20 minutes before I went and
powered it up (I was on minecraft). The box came back with the missing HDD:

Given the outage from yesterday when ada0 was offline for several hours,
I'm guessing that checksum mismatches on that drive are expected. Yes,
/dev/gpt/disk06-live == ada0.
The current zpool status is:
$ zpool status
pool: storage
state: ONLINE
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are
unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.
