NAME
       lvreduce - reduce the size of a logical volume

SYNOPSIS
       lvreduce [-A/--autobackup y/n] [-d/--debug] [-f/--force] [-h/-?/--help]
       {-l/--extents  [-]LogicalExtentsNumber  |  -L/--size  [-]LogicalVolume‐
       Size[kKmMgGtT]} [-t/--test] [-v/--verbose] LogicalVolume[Path]

DESCRIPTION
       lvreduce allows you to reduce the size of a logical volume.  Be careful
       when reducing a logical volume's size, because data in the reduced part
       is lost!!!
       You  should  therefore  ensure  that  any  filesystem  on the volume is
       resized before running lvreduce so that the  extents  that  are	to  be
       removed are not in use.
       Shrinking  snapshot logical volumes (see lvcreate(8) for information to
       create snapshots) is supported as well.
       Sizes will be rounded if necessary - for example, the volume size  must
       be an exact number of extents and the size of a striped segment must be
       a multiple of the number of stripes.

OPTIONS
       See lvm for common options.

       -f, --force
	      Force size reduction without any question.

       -l, --extents [-]LogicalExtentsNumber
	      Reduce or set the	 logical  volume  size	in  units  of  logical
	      extents.	 With the - sign the value will be subtracted from the
	      logical volume's actual size and without it the will be taken as
	      an absolute size.

       -L, --size [-]LogicalVolumeSize[kKmMgGtT]
	      Reduce  or  set  the logical volume size in units of megabyte by
	      default.	A size suffix of k for kilobyte, m for megabyte, g for
	      gigabyte	or  t  for  terabyte is optional.  With the - sign the
	      value will be subtracted from the logical volume's  actual  size
	      and without it it will be taken as an absolute size.

Example
       "lvreduce -l -3 vg00/lvol1" reduces the size of logical volume lvol1 in
       volume group vg00 by 3 logical extents.
