linux下使用ssm存储管理器管理lvm教程

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

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

  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

  Logical volume "snap20160531T120543" created

[root@localhost ~]# ssm list snapshots

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

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

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
