My Notes On LVM

LVM

LVM stands for Logical Volume Management

To initialize a drive as a physical volume we use the pvcreate command. For example if you have the drive /dev/sdX you could use the command.

sudo pvcreate /dev/sdX

You can view your physical volumes and info about them with

sudo pvdisplay

You can view your physical volumes with

pvs

You also might to resize physical volume after resizing a partition, this can be done with the pvresize.

sudo pvresize /dev/sdX

To create a volume group use the command

sudo vgcreate bucket /dev/sdX /dev/example

Here I am calling the volume group bucket. And I am using some physical volumes to create it.

You can view and see info about you Volume Groups with the command

sudo vgdisplay

You can also view them with

sudo vgs

To remove a volume group, you can use the command

sudo vgremove bucket

To create a Logical Volume use the command.

sudo lvcreate -L 15G -n bit bucket
