linux - PV dev/dev/mapper/mpathc 的副本存在于未知设备 8 :96

Question

我已经在 RHEL linux 中配置了多路径。我已将过滤器更改为 "filter = [ "a|/dev/disk/by-id/dm-uuid-.*mpath-.*|", "r|.*|"] ”。之后发出命令 vgscanif 显示跟随错误

我尝试了很多修改 lvm 过滤器的方法。谁能帮我解决这个问题。提前致谢:)

Answer 1

我在Centos 7.2上遇到了同样的问题，在网上搜索后找到了解决方案。

1. 备份你的vg信息，然后恢复vg信息，扫描vg和pv。烦人的信息将消失

2. 操作是

   1. vgcfgbackup;vgcfgbackup -f/root/vgcfg.backup
   2. vgcfgrestore vg01
   3. vgscan;pvscan
   4. vgdisplay vg01
