It does, but it also did not start resilvering the second disk: r...@coyote:~# zpool status pool: tank state: ONLINE 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'. see: http://www.sun.com/msg/ZFS-8000-9P scrub: none requested config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 mirror ONLINE 0 0 0 ad4.eli ONLINE 0 0 0 da0.eli ONLINE 0 0 16 errors: No known data errors Will now run the scrub and report back in 6-9h.
