NAME
       lvresize - resize a logical volume

SYNOPSIS
       lvresize [--alloc AllocationPolicy] [-A/--autobackup y/n] [-d/--debug]
       [-h/-?/--help]  [-i/--stripes  Stripes  [-I/--stripesize	 StripeSize]]
       {-l/--extents  [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE}]  | -L/--size
       [+]LogicalVolumeSize[kKmMgGtT]} [-t/--test] [-v/--verbose] LogicalVol-
       umePath [PhysicalVolumePath...]

DESCRIPTION
       lvresize	 allows	 you  to  resize  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 shrunk first so that the extents that are to be removed are not  in
       use.   Resizing snapshot logical volumes (see lvcreate(8) for informa-
       tion about creating snapshots) is supported as well.   But  to  change
       the number of copies in a mirrored logical volume use lvconvert(8).

OPTIONS
       See lvm for common options.

       -l, --extents [+/-]LogicalExtentsNumber[%{VG|LV|PVS|FREE}]
	      Change  or  set  the  logical  volume  size in units of logical
	      extents.	With the + or - sign the value is added	 to  or	 sub-
	      tracted  from the actual size of the logical volume and without
	      it, the value is taken as an absolute one.  The number can also
	      be  expressed  as a percentage of the total space in the Volume
	      Group with the suffix %VG, relative to the existing size of the
	      Logical  Volume  with  the  suffix  %LV, as a percentage of the
	      remaining free space of the PhysicalVolumes on the command line
	      with  the suffix %PVS, or as a percentage of the remaining free
	      space in the Volume Group with the suffix %FREE.

       -L, --size [+/-]LogicalVolumeSize[kKmMgGtTpPeE]
	      Change or set the logical volume size in units of megabytes.  A
	      size  suffix  of	M  for megabytes, G for gigabytes, T for ter-
	      abytes, P for petabytes or E for exabytes	 is  optional.	 With
	      the  +  or  - sign the value is added to or subtracted from the
	      actual size of the logical volume and without it, the value  is
	      taken as an absolute one.

       -i, --stripes Stripes
	      Gives  the  number  of  stripes to use when extending a Logical
	      Volume.  Defaults to whatever the last segment of	 the  Logical
	      Volume uses.  Not applicable to LVs using the original metadata
	      LVM format, which must use a single value throughout.

       -I, --stripesize StripeSize
	      Gives the number	of  kilobytes  for  the	 granularity  of  the
	      stripes.	 Defaults to whatever the last segment of the Logical
	      Volume uses.  Not applicable to LVs using the original metadata
	      LVM format, which must use a single value throughout.
	      StripeSize must be 2^n (n = 2 to 9)
