mdadm совершают рейд 1 после перезапуска USB-устройств, не доступных больше

Мой mdadm набег программного обеспечения в опасности потери данных???

Мой оба два новых созданных набега 1 на внешних дисках usb ведут себя странно.

Оба были в порядке и восстановленные, и кошка/proc/mdstat показал

Every 10,0s: cat /proc/mdstat                                              Mon May  2 20:38:33 2011

Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md1 : active raid1 sde1[1] sdc1[2](F)
      1953514432 blocks [2/1] [_U]

md0 : active raid1 sdf2[0] sdd2[2](F)
      452462592 blocks [2/1] [U_]

unused devices: <none>

Затем я размонтировал их и выключил диски.

Позже я включил каждую пару в то же время и диспетчер дисков на "ухудшенных" шоу гнома.

Doesnt, которые работают, поскольку я предполагаю, что это работает.

Я должен остановить набег прежде, чем отключить диски?

Что теперь?

mdstat прекрасен все еще, как отправлено выше, никакое запущенное восстановление.

Я не могу смонтировать набеги, файловая система обнаруживается как неизвестная. (должен быть reiserfs),
