LVM：重复的 VG 名称 VolGroup00

我所在的服务器显示重复的 VG 名称。我该如何重命名其中一个 VolGroup 以消除此冲突？

我快速尝试重新命名 VolGroup（可能做错了......）：

[root@dev-server dev]# vgrename /dev/cciss/c0d1 /dev/VolGroup02
      WARNING: Duplicate VG name VolGroup00: zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87 (created here) takes precedence over ifDUDd-ePmZ-Er7H-xwst-70dY-hB3M-6YDNZc

      Volume group name cciss/c0d1 has invalid characters
    [root@dev-server dev]#

输出df -h：

答案1

来自手册页：-

"vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 VolGroup00_tmp"
   changes  the name of the Volume Group with UUID Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 to "VolGroup00_tmp".

...所以对于你的情况：-

vgrename zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87 newvolgroupname

...将使用 ID 重命名卷组zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87到新卷组名称。

答案2

姓名

vgrename — 重命名卷组概要

vgrename [-A|--autobackup {y|n}] [-d|--debug] [-h|-?|--help] [-t|--test] [-v|--verbose] OldVolumeGroup{路径|名称|UUID} NewVolumeGroup{路径|名称} 描述

vgrename 将现有（参见 vgcreate(8)）卷组从 OldVolumeGroup{Name|Path|UUID} 重命名为 NewVolumeGroup{Name|Path}。系统可见的所有卷组都需要具有不同的名称。否则许多 LVM2 命令将拒绝运行或给出警告消息。

当磁盘在机器之间移动时，可能会出现这种情况。如果连接了磁盘，并且它包含的卷组与包含根文件系统的卷组同名，则机器甚至可能无法正确启动。但是，这两个卷组应该具有不同的 UUID（除非磁盘被克隆），因此您可以使用 vgrename 重命名其中一个冲突的卷组。

选项

请参阅 lvm(8) 以了解常用选项。示例

将现有卷组 vg02 重命名为 my_volume_group：vgrename /dev/vg02 /dev/my_volume_group

或者

名称

vg02 我的卷组

将 UUID 为 Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 的卷组名称更改为 VolGroup00_tmp：

vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4

卷组00_tmp

关联：http://linux.die.net/man/8/vgrename

...至于

  Volume group name cciss/c0d1 has invalid characters

/dev/cciss/c0d1不是 VG，因此您无法重命名它。这是一个 PV，VG 可能基于该 PV。
