Lvremove

Internal

• Logical Volume Operations

Overview

Removes a logical volume from a volume group.

Gather statistics on the free space before removing, and also on the size of the logical volume to be removed with vgs and lvs.

Unmount the volume if necessary (or shutdown the service that is using it, as it is the case with Docker):

umount /dev/VolGroup00/MyLV1

Remove the logical volume with lvremove.

The command has a "dry run mode" (-t):

lvremove /dev/<VG_name>/<LV_name>

lvremove -t /dev/<VG_name>/<LV_name>

Example:

[root@rhel-test lvm]# lvremove -t /dev/rhel_rhel-test/docker-pool 
  TEST MODE: Metadata will NOT be updated and volumes will not be (de)activated.
Do you really want to remove active logical volume docker-pool? [y/n]: y
  Logical volume "docker-pool" successfully removed

This command actually removes it:

lvremove [-v] /dev/VolGroup00/MyLV1
