두 개의 디스크가있는 LVM2 볼륨이 있습니다. 더 큰 디스크가 손상되었으므로 pvmove를 사용할 수 없습니다. 다른 디스크에서 가장 많은 데이터를 저장하기 위해 그룹에서 제거하는 가장 좋은 방법은 무엇입니까? 내 pvdisplay 출력은 다음과 같습니다.

그래서 알 수없는 장치 (시스템에없는)를 제거하고 싶습니다. 새 디스크없이이 작업을 수행 할 수 있습니까? 파일 시스템은 ext4입니다.

Removing partial LV LogVol00.
Logical volume "LogVol00" successfully removed
Wrote out consistent volume group vg_srvlinux

--removemissing
Removes all missing physical volumes from the volume group, if there are no logical volumes
allocated on those. This resumes normal operation of the volume group (new logical volumes
may again be created, changed and so on).
If this is not possible (there are logical volumes referencing the missing physical volumes)
and you cannot or do not want to remove them manually, you can run this option with --force
to have vgreduce remove any partial LVs.
Any logical volumes and dependent snapshots that were partly on the missing disks get removed
completely. This includes those parts that lie on disks that are still present.
If your logical volumes spanned several disks including the ones that are lost, you might
want to try to salvage data first by activating your logical volumes with --partial as
described in lvm (8).
