#创建gpt分区表
parted /dev/sdb mklabel gpt

#创建新分区sdb1、sdb2、sdb3
parted /dev/sdb mkpart sdb1 ext3 1G 350G
parted /dev/sdb mkpart sdb2 ext3 351G 700G
parted /dev/sdb mkpart sdb3 ext3 701G 950G

#创建物理卷(可以是整个硬盘、也可以是单个分区)
linux-le62:~ # pvcreate /dev/sdb{1,2,3}
  Physical volume "/dev/sdb1" successfully created
  Physical volume "/dev/sdb2" successfully created
  Physical volume "/dev/sdb3" successfully created

#创建卷组vgbels  
  linux-le62:~ # vgcreate vgbels /dev/sdb{1,2,3}
  Volume group "vgbels" successfully created
 
#创建逻辑卷data、bels、mosdb
lvcreate -L 300G -n data vgbels
lvcreate -L 300G -n bels vgbels
lvcreate -L 200G -n mosdb vgbels

#格式化逻辑卷data、bels、mosdb
linux-le62:~ # mkfs.ext3 /dev/vgbels/data
linux-le62:~ # mkfs.ext3 /dev/vgbels/bels
linux-le62:~ # mkfs.ext3 /dev/vgbels/mosdb

#编辑 vim /etc/fstab，实现开机自动挂载/etc/fstab，实现开机自动挂载
在最后加入以下内容：
/dev/vgbels/data     /data                ext3       defaults              0 0
/dev/vgbels/bels     /bels                ext3       defaults              0 0
/dev/vgbels/mosdb    /mosdb               ext3       defaults              0 0

#挂载所有
linux-le62:~ # mount -a

#查看挂载结果
linux-le62:~ # df -h
