LVM：将多个硬盘和硬盘分区作为一个逻辑卷，并把这个逻辑卷作为一个整体来统一管理，动态对分区进行扩缩空间大小，安全快捷方便管理。一般都是扩大，很少用到缩小的。

小编建议你使用ssm存储管理器。system-storage-manager，管理起来非常方便。ssm存储管理器的安装使用

ssm命令管理LVM

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
---------------------------------------------------------//物理设备
Device        Free     Used      Total  Pool  Mount point
---------------------------------------------------------
/dev/sda                      50.00 GB        PARTITIONED
/dev/sda1                    500.00 MB        /boot     
/dev/sda2                      2.02 GB        SWAP      
/dev/sda3                     47.50 GB        /         
/dev/sdb   4.00 GB  1.00 GB    5.00 GB  vg00            
/dev/sdc   5.00 GB  0.00 KB    5.00 GB  vg00            
/dev/sdd                       5.00 GB                  
/dev/sde                       5.00 GB                  
---------------------------------------------------------
----------------------------------------------//存储池
Pool  Type  Devices     Free     Used    Total 
----------------------------------------------
vg00  lvm   2        8.99 GB  1.00 GB  9.99 GB 
----------------------------------------------
----------------------------------------------------------------------------------//存储池中的LVM卷
Volume          Pool  Volume size  FS      FS size       Free  Type    Mount point
----------------------------------------------------------------------------------
/dev/vg00/lv00  vg00      1.00 GB  ext2    1.00 GB  957.62 MB  linear            
/dev/sda1               500.00 MB  xfs   496.67 MB  406.23 MB  part    /boot     
/dev/sda3                47.50 GB  xfs    47.47 GB   43.87 GB  part    /         
----------------------------------------------------------------------------------

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
---------------------------------------------------------
Device        Free     Used      Total  Pool  Mount point
---------------------------------------------------------
/dev/sda                      50.00 GB        PARTITIONED
/dev/sda1                    500.00 MB        /boot     
/dev/sda2                      2.02 GB        SWAP      
/dev/sda3                     47.50 GB        /         
/dev/sdb   4.00 GB  1.00 GB    5.00 GB  vg00            
/dev/sdc   5.00 GB  0.00 KB    5.00 GB  vg00            
/dev/sdd   5.00 GB  0.00 KB    5.00 GB  vg00            
/dev/sde                       5.00 GB                  
---------------------------------------------------------
------------------------------------------------

------------------------------------------------
vg00  lvm   3        13.99 GB  1.00 GB  14.99 GB 
------------------------------------------------
----------------------------------------------------------------------------------
Volume          Pool  Volume size  FS      FS size       Free  Type    Mount point
----------------------------------------------------------------------------------
/dev/vg00/lv00  vg00      1.00 GB  ext2    1.00 GB  957.62 MB  linear            
/dev/sda1               500.00 MB  xfs   496.67 MB  406.23 MB  part    /boot     
/dev/sda3                47.50 GB  xfs    47.47 GB   43.87 GB  part    /         
----------------------------------------------------------------------------------

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
  Extending logical volume lv00 to 11.00 GiB
  Logical volume lv00 successfully resized

Resizing the filesystem on /dev/mapper/vg00-lv00 to 2883584 (4k) blocks.
The filesystem on /dev/mapper/vg00-lv00 is now 2883584 blocks long.

7.更新文件系统

[root@localhost ~]# mke2fs /dev/vg00/lv00

8.挂载结果

 [root@localhost ~]# df -hT

9.创建新的LVM池

 [root@localhost ~]# mkdir /soft
[root@localhost ~]# ssm create -s 1G -n soft --fstype xfs -p mysoft /dev/sde /soft    
//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
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=0
data     =                       bsize=4096   blocks=262144, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0 ftype=0

11.对LVM卷快照

[root@localhost ~]# ssm snapshot /dev/mysoft/soft

Rounding up size to full physical extent 208.00 MiB

Logical volume "snap20160531T120543" created

[root@localhost ~]# ssm list snapshots

------------------------------------------------------------------------------

Snapshot Origin Pool Volume size Size Type

------------------------------------------------------------------------------

/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

Do you really want to remove active logical volume soft? [y/n]: y

Logical volume "soft" successfully removed
