Здравствуйте!
Словил сегодня благодаря аварийному выключению питания:
$ cat /proc/mdstat
Personalities : [raid1]
read_ahead 1024 sectors
md5 : active raid1 hdc10[0]
174168576 blocks [2/1] [U_]
md4 : active raid1 hdc9[0]
39069952 blocks [2/1] [U_]
[кусь]
Диски живые но raidstart не отработал:
Feb 5 13:19:39 tormoz kernel: md: md5: raid array is not clean --
starting background reconstruction
Feb 5 13:19:39 tormoz kernel: md: md4: raid array is not clean --
starting background reconstruction
Feb 5 13:19:40 tormoz kernel: md: md4: raid array is not clean --
starting background reconstruction
Feb 5 13:19:40 tormoz kernel: raid1: device hdc9 operational as mirror

Feb 5 13:19:40 tormoz kernel: raid1: md4, not all disks are operational
-- trying to recover array
Feb 5 13:19:40 tormoz kernel: raid1: raid set md4 active with 1 out of
2 mirrors
Feb 5 13:19:40 tormoz kernel: md: md5: raid array is not clean --
starting background reconstruction
Feb 5 13:19:40 tormoz kernel: raid1: device hdc10 operational as mirror
0
Feb 5 13:19:40 tormoz kernel: raid1: md5, not all disks are operational
-- trying to recover array
Feb 5 13:19:40 tormoz kernel: raid1: raid set md5 active with 1 out of
2 mirrors
Вопрос, можно ли восстановить рейд без переинициализации?
Кто-нибудь такое лечил?
PS. Чтение манов/howto просветления не принесло.

А а добавлять "вылетевшие" диски с помощью mdadm не пробовали?
$man mdadm
...............
For Manage mode:
-a, --add
hot-add listed devices.
--re-add
re-add a device that was recently removed from an
array.

Да.

raidhotadd или mdadm --add (IIRC)

Главное -- "да", а теперь почитайте поспокойней.
Проверено в подобной ситуации, помогает ;)
