У меня есть деградированный zpool, называемый хранилищем из 4 дисков по 6 ТБ в 2 зеркалах. Один из дисков на втором зеркале недоступен. Кажется, что все кабели физически подключены. Изменился ли идентификатор моего устройства?

edit2 Не понимал, что один диск даже не отображается. Похоже, что 2-й привод в зеркале-1 полностью мертв. Вывод с диска sudo lshw -class помог мне в этом.

Что ж, в выводе четко указано, что один из дисков 250 ГБ. Либо он был заменен, либо он был поврежден, когда он начал ошибочно сообщать о своем пространстве. Взять smartmontools и изучить это с smartctl, он покажет всю информацию об этом.
