Но диски не вечны, и ada0 приказал долго жить. После физической замены диска на новый, видим следующее:# zpool status -xv pool: tank1 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: none requested config: NAME STATE READ WRITE CKSUM tank1 DEGRADED 0 0 0 mirror-0 DEGRADED 0 0 0 3199557894021506640 UNAVAIL 0 0 0 was /dev/ada0p3 ada1p3 ONLINE 0 0 0 errors: No known data errors
- Готовим новый диск
Смотрим, что есть на новом диске:# gpart show ada0 gpart: No such geom: ada0.
Пусто. Если на диск есть разделы, то выполняем команду:# gpart destroy -F ada0
Далее, на ad0 необходимо сделать такие же разделы, как и на ada1.
Смотрим, что есть на ada1:# gpart show ada1 => 34 468862061 ada1 GPT (224G) 34 6 - free - (3.0K) 40 128 1 freebsd-boot (64K) 168 33554432 2 freebsd-swap (16G) 33554600 435307488 3 freebsd-zfs (208G) 468862088 7 - free - (3.5K)И делаем так же на ada0:# gpart create -s gpt ada0 # gpart add -b 40 -s 128 -t freebsd-boot ada0 # gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0 # gpart add -s 33554432 -t freebsd-swap ada0 # gpart add -s 435307488 -t freebsd-zfs ada0
Итого:# gpart show ada0 => 34 468862061 ada0 GPT (224G) 34 6 - free - (3.0K) 40 128 1 freebsd-boot (64K) 168 33554432 2 freebsd-swap (16G) 33554600 435307488 3 freebsd-zfs (208G) 468862088 7 - free - (3.5K)
