one of the drives in my pool got funky. i put it offline
2008-07-26.16:23:44 zpool offline -t tank ad6s1
2008-07-26.16:24:28 zpool offline tank ad6s1
and then replaced it. i rebooted so the hw and driver would be happy
about the drive, and then
# zpool online tank ad6s1
Bringing device ad6s1 online
# zpool status -x
pool: tank
state: DEGRADED
status: One or more devices could not be opened. Sufficient replicas
exist for
the pool to continue functioning in a degraded state.
action: Attach the missing device and online it using 'zpool online'.
