接下来，停止应用（这里停止的应用是NBU）

再转到lvm配置目录中，执行pv和vg的修复操作 [root@backupserver goodies]# cd /etc/lvm/backup [root@backupserver backup]# ls stuvg VolGroup00
[root@backupserver backup]# ls -l

[root@backupserver backup]# pvcreate --restorefile /etc/lvm/backup/stuvg --uuid

[root@backupserver backup]# vgcfgrestore --file /etc/lvm/backup/stuvg stuvg #（重新根据配置文件执行vg修复）
Restored volume group stuvg
到此，pv和vg信息被重新恢复，执行vgdisplay lvdisplay和pvdisplay命令都正常了，接下来重新删除此pv，正确方法应该是先用vgreduce将pv从vg中移除，再使用pvremove删除pv设备，操作如下：
[root@backupserver backup]# lvm

重新启动应用（NBU）

问题解决，此问题是由于对于linux下的lvm管理机制不是很了解，执行顺序错误造成的
