Я надеюсь, что кто-то может мне помочь, пытаясь восстановить пул btrfs, который потерял 1-й диск. Я попытался смонтировать второй диск, и у меня были ошибки fs.
Я снова получил 1-й диск для чтения, но, похоже, он потерял файловую систему, но он не был отформатирован. Ни один из них.
Пожалуйста, кто-нибудь может помочь?
