1.安装ssm
[root@localhost ~]# yum -y install system-storage-manager.noarch 
2.检查硬盘和LVM信息
[root@localhost ~]# sudo ssm list

----------------------------------------------------------------------------------
3.将物理磁盘添加到LVM池中
[root@localhost ~]# ssm add -p vg00 /dev/sdd
  Physical volume "/dev/sdd" successfully created
  Volume group "vg00" successfully extended
4.查看当前存储池
[root@localhost ~]# ssm list

5.扩大LVM卷
[root@localhost ~]# ssm resize -s +10G /dev/vg00/lv00
fsck，来自 util-linux 2.23.2
/dev/mapper/vg00-lv00: 11/65536 files (0.0% non-contiguous), 4763/262144 blocks

//create创建、-s 1G指定大小、-n soft文件名称、--fstype xfs文件系统、-p mysoft指定存储池名称、/dev/sde /soft指定那块磁盘挂载哪个目录上
  Physical volume "/dev/sde" successfully created
  Volume group "mysoft" successfully created
  Logical volume "soft" created
meta-data=/dev/mysoft/soft       isize=256    agcount=4, agsize=65536 blks

11.对LVM卷快照
[root@localhost ~]# ssm snapshot /dev/mysoft/soft
  Rounding up size to full physical extent 208.00 MiB

/dev/mysoft/snap20160531T120543  soft    mysoft    208.00 MB  21.30 KB  linear
------------------------------------------------------------------------------
12.删除LVM卷
[root@localhost ~]# ssm remove /dev/mysoft/soft
Device '/dev/mysoft/soft' is mounted on '/soft' Unmount (N/y/q) ? Y
Do you really want to remove active logical volume snap20160531T120543? [y/n]: y
  Logical volume "snap20160531T120543" successfully removed
