답변1

기본적으로 두 개의 깨진 스냅샷 때문에 이 오류가 발생했습니다.

inactive Snapshot '/dev/ubuntu/rootfs_12.10_20140228_01' [6.00 GiB] inherit
inactive Snapshot '/dev/ubuntu/rootfs_12.10_20140409_00' [6.00 GiB] inherit

이 문제를 해결하기 위해 명령을 사용하여 손상된 스냅샷을 제거했습니다 lvremove.

sudo lvremove /dev/ubuntu/rootfs_12.10_20140228_01

이에 대해 나는 언급했다.이것우편.
