Experimental objective:
Through the concept of logical understanding of this experimental Linux system, able to create and manage logical volumes.
lv: logical, physical partitions or a plurality of physical disk can be made a logical partition called logical volumes.
pv: can do the physical partitions of the logical volume.
vg: volume group, the physical partitions into a volume group corresponds to a pool of storage resources, you can call for the logical volume.
Steps:
1, 2GB of a new partition, new partition as pv
2, just to put a new pv VG
. 3, on the newly created lv VG
. 4, a new file system xfs formatted lv
5, linked to create overload point, mount the new lv
Command:
The first step: a new partition, the partition type set by t, 8e codes for the logical volume
Step Two: Create Logical Volume
[root@system1 Desktop]# partprobeLet partition immediately available
[root@system1 Desktop]# pvcreate /dev/sda3 The sda3 as pv, sda3 partition number can be used to query the fdisk -l
[root@system1 Desktop]# vgcreate vg_0 /dev/sda3 The added volume group sda3 vg_0, vg_0 name may be modified to
[root @ system1 Desktop] # lvcreate -n lv_0 -L 512M vg_0
establishing logical volumes from the volume group vg_0 out in the new logical volume to 512M lv_0 used, can modify the name lv_0
The third step is to mount the logical volume
