Потерянный логический том после сбоя диска и vgreduce (LVM)

Question

У меня огромная проблема с lvm на одном из моих серверов. Один из 3 дисков в одной группе томов поврежден, и у меня нет замены. Поскольку pvdisplay показал "неизвестное устройство" для отсутствующего физического тома, и после некоторого исследования я сделал vgreduce --removemissing --force SAVE, Огромная ошибка, потому что теперь я потерял логический том. Здесь некоторая информация.

Я хотел бы восстановить некоторые данные, я знаю, что это почти невозможно, но если кто-то знает способ, я буду благодарен.

Спасибо всем заранее.
