In link
Logical volume management also shows the same in section "Listing 8. Mounting the LV".

lvremove
LVREMOVE(8) System Manager's Manual LVREMOVE(8)
NAME
lvremove - remove a logical volume
SYNOPSIS
lvremove [-A|--autobackup y|n] [-d|--debug] [-f|--force] [-h|-?|--help] [-t|--test] [-v|--verbose] LogicalVolumePath [LogicalVolumePath...]
DESCRIPTION
lvremove removes one or more logical volumes. Confirmation will be requested before deactivating any active logical volume prior to
removal. Logical volumes cannot be deactivated or removed while they are open (e.g. if they contain a mounted filesystem). Removing an
origin logical volume will also remove all dependent snapshots.
If the logical volume is clustered then it must be deactivated on all nodes in the cluster before it can be removed. A single lvchange com-
mand issued from one node can do this.
OPTIONS
See lvm(8) for common options.
-f, --force
Remove active logical volumes without confirmation.
EXAMPLES
Remove the active logical volume lvol1 in volume group vg00 without asking for confirmation:
lvremove -f vg00/lvol1
Remove all logical volumes in volume group vg00:
lvremove vg00
