RHEL7使用ssm命令管理LVM的方法

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  /     ----------------------------------------------------------------------------------
