LVM：重複的 VG 名稱 VolGroup00
我在顯示重複 VG 名稱的伺服器上。如何重命名這些 VolGroup 之一以擺脫這種衝突？

從手冊頁： -
"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".…所以對於您的情況：-
vgrename zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87 newvolgroupname…將 ID為 zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87的捲組重命名為newvolgroupname。
姓名
vgrename - 重命名卷組
虛擬名字
$$ -A|–autobackup {y|n} $$ $$ -d|–debug $$ $$ -h|-?|–help $$ $$ -t|–test $$ $$ -v|–verbose $$OldVolumeGroup{Path|Name|UUID} NewVolumeGroup{Path|Name} 描述 vgrename 將現有的（參見 vgcreate(8)）卷組從 OldVolumeGroup{Name|Path|UUID} 重命名為 NewVolumeGroup{Name|Path}。系統可見的所有捲組都需要具有不同的名稱。否則許多 LVM2 命令將拒絕執行或給出警告消息。
當磁碟在機器之間移動時，可能會出現這種情況。如果磁碟已連接並且它包含與包含根文件系統的捲組同名的捲組，則機器甚至可能無法正確啟動。但是，兩個卷組應該具有不同的 UUID（除非磁碟被複製），因此您可以使用 vgrename 重命名衝突的捲組之一。
選項
有關常用選項，請參閱 lvm(8)。例子
將現有捲組 vg02 重命名為 my_volume_group：vgrename /dev/vg02 /dev/my_volume_group
或者
虛擬名字
vg02 my_volume_group
將 UUID Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 的捲組的名稱更改為 VolGroup00_tmp：
vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4
VolGroup00_tmp

……至於
Volume group name cciss/c0d1 has invalid characters
/dev/cciss/c0d1不是VG，所以你不能重命名它。這是 VG 可能基於的 PV。
