## 补充说明

|
**vgcreate命令** 用于创建LVM卷组。卷组（Volume Group）将多个物理卷组织成一个整体，屏蔽了底层物理卷细节。在卷组上创建逻辑卷时不用考虑具体的物理卷信息。

使用vgcreate命令创建卷组 "vg1000"，并且将物理卷`/dev/sdb1`和`/dev/sdb2`添加到卷组中。在命令行中输入下面的命令：
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
[root@localhost ~]# vgcreate vg1000 /dev/sdb1 /dev/sdb2 #创建卷组"vg1000"
|
|
|
|
|
|
```
|
