作为灾难恢复练习，我拔掉了属于镜像逻辑卷一部分的驱动器 (/dev/sda) 的插头。我能够通过以下方式使系统可启动
vgreduce --removemissing --force kubuntu-vg
lvs报告
WARNING: ignoring metadata seqno 118 on /dev/sda5 for seqno 120 on /dev/sdb1 for VG kubuntu-vg.

但现在我想撤消该操作 - 因此我重新插入驱动器，现在我需要将该驱动器作为物理卷重新安装到系统上
物理卷过去是什么样子

来自这个 golinuxcloud 文档 在 Linux 中恢复 LVM2 分区、PV、VG、LVM 元数据的 5 个简单步骤 我认为我想要运行的命令是带有 --restorefile 选项的 pvcreate 。 golinuxcloud 建议首先在测试模式下运行它
pvcreate --test --uuid "X5FdPD-xkae-gXSe-wSbH-ngl7-SiPD-EjeYP6" --restorefile /etc/lvm/archive/kubuntu-vg_00002-168403895.vg /dev/sda
TEST MODE: Metadata will NOT be updated and volumes will not be (de)activated.

在我看来，这里阻止成功的是“设备 /dev/sda 被过滤器排除”。对此你该怎么办？
我的命令中引用的备份文件是vgcfgrestore --list kubuntu-vg这样描述的
