다음 질문이 있습니다. 내 노트북은 LVM을 사용하여 완전히 암호화되어 있으며 비밀번호는 알고 있지만 파티션 테이블이 손상되었습니다. 이 예에서는 USB 스틱 sdb1에서 부팅했습니다. /dev/sda2를 다시 작동시킬 수 있을까요? sda1 ist mountable 부팅하려고 하면 initframes에 멈춰 볼륨 그룹을 찾을 수 없습니다.
시스템은 Linux Mint Qiana입니다.

저는 kali를 설치한 기억이 전혀 없습니다. ;-) 아마도 처음에 제 컴퓨터에 붙인 이름이었을 것입니다(저는 많이 가지고 놀았습니다. -.-) 보시다시피, sda2는 제 데이터가 있는 곳입니다 . 대략 4GB의 스왑 공간이 있습니다. 그런 다음 이미지 파일은 DHEX로 분석됩니다.
편집 2: 추가 정보
dhex를 기다리는 동안 웹을 검색했는데 이것이 내가 얻은 것입니다.
지금까지 내 Hexdump.

그렇다면 문제는 무엇입니까?
491GB 기기를 보고 nemo를 통해 마운트를 해보았습니다. 이것은 잘못된 것입니다.

In some cases useful info is found in syslog - try
dmesg | tail or so
이것이 dmesg|tail이 제공하는 것입니다.
