将另一块装了系统的盘插入现在的系统中,出现lvm两个卷同名,则需要对另一个进行重命名

[root@sunss ~]# lvscan ACTIVE '/dev/VolGroup00/LogVol00' [72.47 GB] inherit ACTIVE '/dev/VolGroup00/LogVol01' [1.94 GB] inherit [root@sunss ~]# pvs PV VG Fmt Attr PSize PFree /dev/sda2 VolGroup00 lvm2 a- 148.94G 0 /dev/sdb2 VolGroup00 lvm2 a- 74.41G 0 [root@sunss ~]# /sbin/pvscan PV /dev/sdb2 VG VolGroup00 lvm2 [74.41 GB / 0 free] PV /dev/sda2 VG VolGroup00 lvm2 [148.94 GB / 0 free] Total: 2 [223.34 GB] / in use: 2 [223.34 GB] / in no VG: 0 [0 ]

两个VG名称居然一样,先查看UUID

#改名 [root@sunss ~]# vgrename SYhnZ2-h4ol-C8x0-KUlu-AbKW-np2q-t51OP1 VolGroup01 Volume group "VolGroup00" successfully renamed to "VolGroup01"

#激活

[root@sunss ~]# vgchange -a y /dev/VolGroup01 2 logical volume(s) in volume group "VolGroup01" now active

#名字不一样了，可以挂载了
