LinuxCentOS7关于PV name券显示[unknown]问题

[root@bogon ~]# pvsWARNING: Device for PV NJQyPM-K2N8-vk2O-04IG-GmS8-IGxZ-FJt1rj not found or rejected by a filter.PV         VG     Fmt  Attr PSize   PFree/dev/sda2  centos lvm2 a--  <19.00g      0[unknown]  centos lvm2 a-m  <10.00g <10.00g

这个问题是啥东西啊？我也没有瞎胡创建还是怎么着啊，就是不能正常使用了。
使用pvremove告知如下：

[root@bogon ~]# pvremove [unknown]WARNING: Device for PV NJQyPM-K2N8-vk2O-04IG-GmS8-IGxZ-FJt1rj not found or rejected by a filter.Device [unknown] not found (or ignored by filtering).

？？？？这下我就迷糊了，还不能删除。。。
告诉我什么找不到的意思，可是我查询明明是有的。
我又看了眼 发现vg name名称相同，会不会是重名导致的？？于是我又vgrename ：

[root@bogon ~]# vgrename centos centos01WARNING: Device for PV NJQyPM-K2N8-vk2O-04IG-GmS8-IGxZ-FJt1rj not found or rejected by a filter.Cannot change VG centos while PVs are missing.Consider vgreduce --removemissing.Cannot process volume group centos

瓦特？？？还是不行？？？
它上面让我使用vgreduce --removemissing. 来删除相关的vg卷
于是我照做：

[root@bogon ~]# vgreduce --removemissing centos
/dev/sda2  [unknown]
[root@bogon ~]# vgreduce --removemissing centos [unknown]Command does not accept argument: [unknown].

这也不行，这可咋整？？？？？
我想是不是把这个分区给格式化了就能恢复？（我这个分区没有数据文件，诸位有数据文件的不要乱格式化。）

我格式化了空间又重新分区，敲了下vgdisplay 显示为Free PE还有10G空间。。。格式化空间也不好用。。。
准备放弃的时候有一条命令恢复了，就是根据PV的UUID来恢复不正常的pv卷名称：
我先查看PVUUID 可以用pvdisplay查看PVUUID

       yes (but full)PE Size               4.00 MiBTotal PE              4863Free PE               0Allocated PE          4863PV UUID               UrT1kL-3iRj-c120-mRF5-SkbV-1ca1-m3SqfI--- Physical volume ---PV Name               /dev/sdb1VG Name               centosPV Size               <10.00 GiB / not usable 3.00 MiBAllocatable           yesPE Size               4.00 MiBTotal PE              2559Free PE               2559Allocated PE          0PV UUID               NJQyPM-K2N8-vk2O-04IG-GmS8-IGxZ-FJt1rj

也可以查看/etc/lvm/backup/下生成的pv创建备份文件来找到PVUUID：

[root@bogon ~]# vim /etc/lvm/backup/centos# Generated by LVM2 version 2.02.171(2)-RHEL7 (2017-05-03): Thu Apr 22 20:58:42 2021contents = "Text Format Volume Group"

拿着PVUUID 去恢复pvname名称：

[root@bogon ~]# pvcreate /dev/sdb1 -u NJQyPM-K2N8-vk2O-04IG-GmS8-IGxZ-FJt1rj --restorefile /etc/lvm/backup/centosCouldn't find device with uuid NJQyPM-K2N8-vk2O-04IG-GmS8-IGxZ-FJt1rj.WARNING: Device for PV NJQyPM-K2N8-vk2O-04IG-GmS8-IGxZ-FJt1rj not found or rejected by a filter.

[root@bogon ~]# pvsPV         VG     Fmt  Attr PSize   PFree/dev/sda2  centos lvm2 a--  <19.00g      0/dev/sdb1  centos lvm2 a--  <10.00g <10.00g

这里可以看见使用pvcreate指定有问题的pvuuid号重新生成pvname就回复了。。。我的天，真够麻烦的。。
一条命令 我找了半天都没找出恢复pvname的解决方法。。
