운영 체제를 다시 설치한 후 lvm 파티션을 다시 마운트하십시오.

최근 Ubuntu에서 Linux Mint로 업그레이드했습니다. 우분투를 다루었습니다 /dev/sda2. 이전에 /dev/sda1 opt에서 virtualization두 개의 논리 볼륨을 만들었습니다 . lvm 파티션 메타데이터 백업을 수행하는 것을 잊었습니다. 하지만 설치했을 때 lvm2이 메타데이터를 복원한 것 같습니다 .

1. /opt이러한 논리 볼륨을 및 에 어떻게 마운트합니까 /virtualization?
2. 또한 lvm2파티션 메타데이터를 복구하려면 어떻게 해야 합니까?
