Срочно нужна помощь в восстановлении данных, NAS DS3612xs. В системе 12 дисков по 4Тб. Объеденены все в один массив RAID5+Hot spare. Пару дней назад система отключила один диск из за большого количества сбойных секторов. На экране в панеле управления вылезло какое то сообщение о сбое, я нажал ок. Спустя несколько часов никакой реакции. Сбойный диск #7 был помечен желтой лампой, еще один диск активно моргал ламой считывания данных, все остальные молчали. Тогда я решил произвести замену сбойного диска, выдернул и вставил новый, точно такой же. После этой процедуры сервер активно поморгал всеми дисками после чего завис, не реагировал и не отвечал на запросы. Лампа на одном из дисков продолжала моргать. Консоль по SSH была недоступна, и панель по веб тоже не отвечала. Вообщем я был вынужден перезапустить сервер принудительно. После загрузки опять вылезло сообщение о сбое, но на этот раз раздел с данными куда то пропал. Я зашел в управление разделами и нажал на проверку раздела на четность. После завершения проверки данные не появились, пробовал перезагружать сервер через панель, ничего не помогает. После перезагрузки пишет раздел или диск поврежден. Через консоль посмотрел статус MDADM

Не совсем понимаю что за массивы md0 и md1, у меня диски были объеденены в один массив.
