本文主要是介绍4.11-Lvm讲解（中）创建卷组，创建逻辑卷，扩容逻辑卷，缩容逻辑卷，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
创建卷组
[root@evan-01 ~]# vgcreate vg1 /dev/sdb1 /dev/sdb2Volume group "vg1" successfully created
[root@evan-01 ~]#
查看卷组

创建逻辑卷
[root@evan-01 ~]# lvcreate -L 100M -n 1v1 vg1Logical volume "1v1" created.
[root@evan-01 ~]#
