[root@node4 lvmTest]# vgreduce --removemissing --force vgTest
Couldn't find device with uuid zecO8D-2Suc-rnmK-a2Z7-6613-Zy1X-whVS0X.

5、向卷组中加入新的物理卷（/dev/sde）：
复制代码
[root@node4 lvmTest]# vgextend vgTest /dev/sde
Volume group "vgTest" successfully extended
复制代码
[root@node4 lvmTest]#
6、进行数据恢复（过程中无须解除逻辑卷的挂载）
复制代码
[root@node4 lvmTest]# lvconvert -m1 /dev/vgTest/lvTest /dev/sdb /dev/sdd /dev/sde
vgTest/lvTest: Converted: 0.0%
vgTest/lvTest: Converted: 100.0%
复制代码
[root@node4 lvmTest]# lvs -a -o +devices
