Some days, when it’s cold and you’re not feeling very motivated (like me, today), it’s nice to do a zpool scrub on the machines you manage, and then once it’s done:
$ zpool status pool: aux state: ONLINE scrub: scrub completed with 0 errors on Tue Jan 29 15:52:38 2008 config: NAME STATE READ WRITE CKSUM aux ONLINE 0 0 0 mirror ONLINE 0 0 0 c1t0d0s7 ONLINE 0 0 0 c1t1d0s7 ONLINE 0 0 0 errors: No known data errors
And then relax, knowing that your data is safe.
