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 information 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  subtracted  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 terabytes,  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)
