4.4.6. Removing Logical Volumes

To remove an inactive logical volume, use the lvremove command. You must close a logical volume with the umount command before it can be removed. In addition, in a clustered environment you must deactivate a logical volume before it can be removed.

If the logical volume is currently mounted, unmount the volume before removing it.

The following command removes the logical volume /dev/testvg/testlv. from the volume group testvg. Note that in this case the logical volume has not been deactivated. 

[root@tng3-1 lvm]# lvremove /dev/testvg/testlv
Do you really want to remove active logical volume "testlv"? [y/n]: y
  Logical volume "testlv" successfully removed

You could explicitly deactivate the logical volume before removing it with the lvchange -an command, in which case you would not see the prompt verifying whether you want to remove an active logical volume.
