lv增加磁盘

1.查看当前硬盘及分区情况

[root@localhost ~]# fdisk -l

其中/dev/sdb是我需要增加的硬盘

2.初始化/dev/sdb为PV(physical volume)

命令如下:

[root@localhost ~]# pvcreate /dev/sdb
  Physical volume "/dev/sdb" successfully created

3.PV加入至VG组。

[root@localhost ~]# vgcreate VGroup00 /dev/sdb
  Volume group "VGroup00" successfully created

4.创建lv

[root@localhost ~]# lvcreate -l +100%free -n LVol00 VGroup00
  Logical volume "LVol00" created.

以上命令，把所有的空闲空间划至/dev/VGroup00/LVol00空间中。

5.格式化逻辑分区

[root@localhost ~]# mkfs.ext4 /dev/VGroup00/LVol00

6.挂载硬盘/data

[root@localhost ~]# mkdir -p /data
[root@localhost ~]# mount /dev/VGroup00/LVol00 /data

7.总结

fdisk -l
pvcreate /dev/sdb
vgcreate VGroup00 /dev/sdb
lvcreate -l +100%free -n LVol00 VGroup00
mkfs.xfs /dev/VGroup00/LVol00
mkdir -p /data
mount /dev/VGroup00/LVol00 /data
