lvm2/man/lvremove.8_des

lvremove removes one or more LVs. For standard LVs, this returns the
logical extents that were used by the LV to the VG for use by other LVs.
.P
Confirmation will be requested before deactivating any active LV prior to
removal.  LVs cannot be deactivated or removed while they are open (e.g.
if they contain a mounted filesystem). Removing an origin LV will also
remove all dependent snapshots.
.P
When a single force option is used, LVs are removed without confirmation,
and the command will try to deactivate unused LVs.
.P
To remove damaged LVs, two force options may be required (\fB-ff\fP).
.P
\fBHistorical LVs\fP
.P
If the configuration setting \fBmetadata/record_lvs_history\fP is enabled
and the LV being removed forms part of the history of at least one LV that
is still present, then a simplified representation of the LV will be
retained. This includes the time of removal (\fBlv_time_removed\fP
reporting field), creation time (\fBlv_time\fP), name (\fBlv_name\fP), LV
uuid (\fBlv_uuid\fP) and VG name (\fBvg_name\fP). This allows later
reporting to see the ancestry chain of thin snapshot volumes, even after
some intermediate LVs have been removed. The names of such historical LVs
acquire a hyphen as a prefix (e.g. '-lvol1') and cannot be reactivated.
Use lvremove a second time, with the hyphen, to remove the record of the
former LV completely.
