손상된 파일 시스템을 복구하는 방법은 무엇입니까?

손상된 파일 시스템을 복구하는 방법은 무엇입니까?

오늘 내 NAS가 오프라인 상태입니다. 부팅도 안 되네요. OS 드라이브(Debian Bookworm)를 추출하고 어댑터를 통해 노트북에 연결했습니다. 다음 오류로 인해 설치에 실패했습니다. 알 수 없는 파일 시스템 유형 'LVM2_member'

파일 시스템이 어떻게든 손상되었거나(며칠 전에 전원이 나갔음) SSD가 죽어가고 있는 것 같습니다(3년 미만). 무엇이 잘못되었는지 이해하고 가능하다면 수정하고 싶습니다. 결과는 다음과 같습니다정보(삽입 직후),LV 디스플레이,광전지 디스플레이,,디스크 드라이브그리고LSBLK.

블랙리스트에 추가/교체해야 하는 불량 블록이 있다고 생각하지만 하드웨어 문제를 조사할 때는 도저히 할 수 없는 일입니다. 설치가 어떻게 될지 잘 모르겠습니다(아래 참조).

fsck를 실행해도 도움이 되지 않았습니다(재부팅 사이에 장치 문자가 변경됨).

neela@hooban:~$ sudo fsck /dev/sdc
fsck from util-linux 2.34
e2fsck 1.45.5 (07-Jan-2020)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdc

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
 or
    e2fsck -b 32768 <device>
