У меня поврежденная конфигурация RAID-1, и я пытаюсь устранить проблему, независимо от того, полностью ли он мертв (и нужно отправить диск обратно поставщику) или его можно вернуть.
Так что я побежал smartctl:
root@linux:~# smartctl -l selftest /dev/sda
smartctl 6.5 2016-01-24 r4214 [x86_64-linux-4.4.0-176-generic] (local build)

# 1 Extended offline Completed without error 00% 1930 -
# 2 Short offline Completed without error 00% 1930 -
# 3 Extended offline Completed without error 00% 1930 -
Выглядит хорошо. Давайте посмотрим на другие вещи:

Я попытался просмотреть вывод, но, к сожалению, я не эксперт в анализе вывода smartctl. В нем говорилось, что диск прошел тесты:
SMART overall-health self-assessment test result: PASSED
В разделе порогов все в порядке (это довольно новый жесткий диск WD Red, которому несколько месяцев).
Однако в конце вывода есть масса ошибок. Я безуспешно пытался их найти.
С другой стороны, я вообще не могу использовать диск:
root@idealib:~# fdisk /dev/sda
Welcome to fdisk (util-linux 2.27.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
fdisk: cannot open /dev/sda: Input/output error
dmesg тоже плохо выглядит:

Какой еще тест мне следует провести, чтобы быть на 100% уверенным, что диск неисправен и мне нужно его заменить? Или он мертв, и я должен просто принять его? :)
Я не могу помочь с данными SMART (я не настолько умен!), Но мой инструмент по умолчанию, чтобы тыкать в диск, - это плохие блоки.
Инструмент для поиска сбойных блоков на жестком диске. Если вы в порядке с удалением данных, стоит запустить его в деструктивном режиме - обратите внимание, это займет некоторое время !:
badblocks -wsv /dev/sda
На вики Arch (https://wiki.archlinux.org/index.php/badblocks) об инструменте и о том, как им пользоваться.
Еще один инструмент, который вы можете попробовать, - это Spinrite, который при загрузке работает из среды freedos. Он немного староват, но находится на диске довольно низко. Я бы предложил сканирование уровня 4, если вы его используете. https://www.grc.com/sr/spinrite.htm
Я уверен, что вы уже это сделали, но я всегда предлагаю проверить / заменить кабель SATA, порт на материнской плате и т. Д. Я сталкивался с подобными проблемами чаще, чем я хотел бы признать.
