所以，我有磁盘故障，并将LV从故障磁盘移动到新的PV。 一些LV成功移动，有些则不成功。 之后，我以下列状态结束： – 两个locking的LV – 缺lessPV的卷组
当我尝试删除PV时，我得到：
vgreduce --removemissing --force vg3 Couldn't find device with uuid RQr0HS-17ts-1k6Y-Xnex-IZwi-Y2kM-vCc5mP. Removing partial LV var. Can't remove locked LV var lvremove -fff vg3/var Couldn't find device with uuid RQr0HS-17ts-1k6Y-Xnex-IZwi-Y2kM-vCc5mP. Can't remove locked LV var pvmove --abort Couldn't find device with uuid RQr0HS-17ts-1k6Y-Xnex-IZwi-Y2kM-vCc5mP. Cannot change VG vg3 while PVs are missing. Consider vgreduce --removemissing. Skipping volume group vg3 我也尝试执行vcfgbackup，然后编辑锁后，恢复，但无济于事：
vgcfgrestore --force vg3 Couldn't find device with uuid RQr0HS-17ts-1k6Y-Xnex-IZwi-Y2kM-vCc5mP. Cannot restore Volume Group vg3 with 1 PVs marked as missing. Restore failed.
所以我走得更远了，把磁盘插回去了 – 失败了，但可以检测一下。

而这正是我不知道的时刻。
