RHEL7 method of using SSM command to manage LVM _linux

1. Install SSM

[root@localhost ~]# yum-y Install System-storage-manager.noarch

2. Check hard drive and LVM information

[root@localhost ~]# sudo SSM list---------------------------------------------------------//physical device Device free Used Total Pool Mount point---------------------------------------------------------/dev/sda 50.00 GB PARTITION     
ED/DEV/SDA1 500.00 mb/boot/dev/sda2 2.02 GB Swap/dev/sda3 47.50 GB/

3. Add physical disks to the LVM pool

[Root@localhost ~]# SSM add-p vg00/dev/sdd Physical volume '/DEV/SDD ' successfully created ' volume
 Group "vg00" s Uccessfully Extended

4. View current Storage Pool

[root@localhost ~]# SSM list---------------------------------------------------------Device free Used Total Pool Mount Point---------------------------------------------------------/dev/sda 50.00 GB PARTITIONED/DEV/SDA 1 500.00 mb/boot/dev/sda2 2.02 GB Swap/dev/sda3 47.50 GB//dev/sdb 4

5. Expand LVM Volume

[Root@localhost ~]# SSM resize-s +10g/dev/vg00/lv00
fsck from 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
 cessfully resized
resize2fs 1.42.9 (28-dec-2013)
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. Update the file system

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

8. Mounting results

[root@localhost ~]# df-ht

9. Create a new LVM pool

[Root@localhost ~]# mkdir/soft
[root@localhost ~]# SSM create-s 1g-n soft--fstype xfs-p] mysoft/dev/sde/soft
   
    //create creation,-s 1G specified size,-n soft file name 、--fstype xfs file System,-p Mysoft Specify the storage pool name,/dev/sde/soft specify which directory on which to Mount

11. For LVM Volume snapshots

[Root@localhost ~]# SSM Snapshot/dev/mysoft/soft
 rounding up size to full physical extent 208.00 MiB

12. Remove LVM volumes

[Root@localhost ~]# SSM remove/dev/mysoft/soft
