Мое программное обеспечение mdadm подвергается риску потери данных ???
Мои два новых встроенных raid-1 на внешних usb-дисках ведут себя странно.
Оба были в порядке и восстановлены, и cat /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 одно и то же время, и диспетчер дисков в gnome показывал "деградацию".
Разве это не работает, как я полагаю, это работает.
Должен ли я остановить рейд перед отключением дисков?
Что теперь?
mdstat все еще в порядке, как указано выше, восстановление не началось.
Я не могу смонтировать рейды, файловая система отображается как неизвестная. (должно быть reiserfs)
