zpool
Смотрим состояние массива:
# zpool status 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'. see: http://illumos.org/msg/ZFS-8000-2Q scan: resilvered 10.5G in 0h9m with 0 errors on Mon Feb 1 09:49:38 2016 config: NAME STATE READ WRITE CKSUM tank DEGRADED 0 0 0 mirror-0 DEGRADED 0 0 0 ada1p3 ONLINE 0 0 0 9066085129501579450 UNAVAIL 0 0 0 was /dev/ada0p3 errors: No known data errors
Копируем разметку с рабочего диска:
# gpart backup ada1 | gpart restore -F /dev/ada0
Монтируем:
# zpool import -o altroot=/mnt tank
Добавляем:
# zpool replace tank 9066085129501579450 ada0p3 Make sure to wait until resilver is done before rebooting. If you boot from pool 'tank', you may need to update boot code on newly attached disk 'ada0p3'. Assuming you use GPT partitioning and 'da0' is your new boot disk you may use the following command: gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0
Ставим загрузчик:
# gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0 bootcode written to ada0
Проверяем:
