查到数据盘的uuid是bAydq6-rv9e-wCa0-iK2f-zFWn-UBUr-4AR3Ct,改卷组名的时候用uuid,如下:
[root@locallhost ~]# vgrename bAydq6-rv9e-wCa0-iK2f-zFWn-UBUr-4AR3Ct aaalvm
Volume group "VolGroup00" successfully renamed to "aaalvm"
ok了,改完再vgs看下:
[root@locallhost ~]# vgs
VG #PV #LV #SN Attr VSize VFree
VolGroup00 1 2 0 wz--n- 74.41G 0
aaalvm 1 2 0 wz--n- 232.78G 0
没问题了,再lvscan下:
[root@locallhost ~]# lvscan
inactive '/dev/aaalvm/LogVol00' [228.84 GB] inherit
inactive '/dev/aaalvm/LogVol01' [3.94 GB] inherit
ACTIVE '/dev/VolGroup00/LogVol00' [70.47 GB] inherit
ACTIVE '/dev/VolGroup00/LogVol01' [3.94 GB] inherit
已经看到新改名的卷组是inactive了,2个分区LogVol00和LogVol01,用vgchange加载我们该名过的aaalvm卷组:
[root@locallhost ~]# vgchange -ay /dev/aaalvm
2 logical volume(s) in volume group "aaalvm" now active
提示active状态成功,最后mount文件系统:
[root@locallhost ~]# ls /dev/aaalvm/
LogVol00 LogVol01
[root@locallhost ~]# mount /dev/aaalvm/LogVol00 /aaaa/
[root@locallhost ~]# df -h

[root@locallhost ~]# mount /dev/aaalvm/LogVol01 /bbb/
/dev/aaalvm/LogVol01 looks like swapspace - not mounted
mount: you must specify the filesystem type
LogVol01是swap分区,不用挂载。把/bin/mount /dev/aaalvm/LogVol00 /aaaa/写入rc.local里面,让每次开机自动挂载,也可以写到fstab里面,但是如果写错出问题可能导致进不了系统,所以建议写rc.local。
