我是靠谱客的博主高兴萝莉，最近开发中收集的这篇文章主要介绍RHEL7使用ssm命令管理LVM的方法，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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         
---------------------------------------------------------
------------------------------------------------
Pool Type Devices   Free   Used   Total 
------------------------------------------------
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.

6.查看结果

[root@localhost ~]# ssm list
---------------------------------------------------------
Device    Free   Used   Total Pool Mount point
---------------------------------------------------------
/dev/sda           50.00 GB    PARTITIONED

/dev/sda3        47.50 GB xfs  47.47 GB  43.87 GB part  /     
----------------------------------------------------------------------------------

7.更新文件系统

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

8.挂载结果

[root@localhost ~]# df -hT
文件系统       类型   容量 已用 可用 已用% 挂载点
/dev/sda3       xfs    48G 3.6G  44G  8% /

/dev/mapper/vg00-lv00 ext2    11G 5.0M  11G  1% /mnt

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
log   =internal log      bsize=4096  blocks=2560, version=2
     =            sectsz=512  sunit=0 blks, lazy-count=1
realtime =none          extsz=4096  blocks=0, rtextents=0

10.查看结果

[root@localhost ~]# ssm list

/dev/sda3          47.50 GB xfs   47.47 GB  43.87 GB part  /     
----------------------------------------------------------------------------------------

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
