How worried should I be - One or more devices has experienced an unrecoverable error

[Neil Whitworth]

This morning I woke up to find that I had lost power to the computer room (a.k.a the loft) and everything was off. Since this was the first real test of my UPS I wanted to make sure all my data was safe and started a scrub, which almost imediatly reported some errors.

• /var/log/messages seams to show the system shutting down cleanly during power outage.
• S.M.A.R.T data appears OK to me
• long tests started via smartctl -t long /dev/ada0..4 (~40% complete so far)

Have I missed anything? Should I be woried about the errors?

You should investigate the error but no need to worry about your data, it's safe ;)
