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

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.
