Привет
есть сервер с софтовым raid 1
из двух ssd-дисков 120G
Один из дисков временами выпадает из рейда и становится не доступным до перезагрузки, после перезагрузки вновь без ошибок возвращается в рейд. Не могу понять из-за чего
В messages такие ошибкиSep 17 18:55:42 kernel: sd 3:0:0:0: [sdb] FAILED Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK
