VG 中已锁定的 LVM 逻辑卷，缺少 PV

VG 中已锁定的 LVM 逻辑卷，缺少 PV

因此，我遇到了磁盘故障，并将 LV 从故障磁盘移动到新的 PV。一些 LV 移动成功，一些没有。之后我最终处于以下状态：- 两个锁定的 LV - 卷组缺少 PV

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

我还尝试执行 vcfgbackup，然后在编辑锁后恢复，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.

所以我更进一步，将磁盘插回去 - 它失败了，但可以检测到一段时间。

vgreduce --removemissing vg3
  /dev/vg3/var: read failed after 0 of 4096 at 9638445056: Input/output error
  /dev/vg3/var: read failed after 0 of 4096 at 9638502400: Input/output error
  WARNING: Partial LV var needs to be repaired or removed.
  WARNING: Partial LV pvmove1 needs to be repaired or removed.
  There are still partial LVs in VG vg3.
  To remove them unconditionally use: vgreduce --removemissing --force.
  Proceeding to remove empty missing PVs.

lvremove -fff vg3/var
  /dev/vg3/var: read failed after 0 of 4096 at 9638445056: Input/output error
  /dev/vg3/var: read failed after 0 of 4096 at 9638502400: Input/output error
  Can't remove locked LV var

pvmove --abort
  /dev/vg3/var: read failed after 0 of 4096 at 9638445056: Input/output error
  /dev/vg3/var: read failed after 0 of 4096 at 9638502400: Input/output error
  Cannot change VG vg3 while PVs are missing.
  Consider vgreduce --removemissing.
  Skipping volume group vg3

而此刻我已经没有主意了。

如同无法删除卷组，通过创建具有相同 uuid 的临时 pv 解决了此问题：

UUID="RQr0HS-17ts-1k6Y-Xnex-IZwi-Y2kM-vCc5mP"  # from question
dd if=/dev/zero of=/tmp/tmp.raw bs=1M count=100 
losetup -f
losetup /dev/loop0 /tmp/tmp.raw
pvcreate --norestorefile -u $UUID /dev/loop0   # it has arisen!
killall lvmetad      # so it stops complaining about duplicate uuids
pvremove /dev/loop0  # a clean removal 
losetup -D
pvscan --cache       # to restart lvmetad

如果需要的话，用vgreduce等等调味。
