Hey folks,
Well, I've had a disk fail in my home server, so I've had my first experience
of hunting down the faulty drive and replacing it (damn site easier on Sun kit
than on a home built box I can tell you!).
All seemed well, I replaced the faulty drive, imported the pool again, and
kicked off the repair with:
# zpool replace zfspool c1t1d0
But then a few minutes later I noticed this:
# zpool status
pool: zfspool
state: DEGRADED
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'.

scrub: resilver in progress for 0h5m, 1.35% done, 6h46m to go
