NAME
       lvextend - extend the size of a logical volume

SYNOPSIS
       lvextend	 [--alloc AllocationPolicy] [-A/--autobackup y/n] [-d/--debug]
       [-h/-?/--help]  [-i/--stripes  Stripes  [-I/--stripesize	  StripeSize]]
       {-l/--extents  [+]LogicalExtentsNumber  |  -L/--size  [+]LogicalVolume‐
       Size[kKmMgGtT]} [-t/--test]  [-v/--verbose]  LogicalVolumePath  [Physi‐
       calVolumePath...]

DESCRIPTION
       lvextend	 allows you to extend the size of a logical volume.  Extension
       of snapshot logical volumes (see lvcreate(8) for information to	create
       snapshots) is supported as well.

OPTIONS
       See lvm for common options.

       -l, --extents [+]LogicalExtentsNumber
	      Extend  or  set  the  logical  volume  size  in units of logical
	      extents.	With the + sign the value is added to the actual  size
	      of  the  logical volume and without it, the value is taken as an
	      absolute one.

       -L, --size [+]LogicalVolumeSize[kKmMgGtT]
	      Extend or set the logical volume	size  in  units	 in  units  of
	      megabytes.  A size suffix of M for megabytes, G for gigabytes or
	      T for terabytes is optional.  With the + sign the value is added
	      to  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 for the extension.   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.	 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)

Examples
       "lvextend -L +54 /dev/vg01/lvol10 /dev/sdk3" tries to extend  the  size
       of  that	 logical volume by 54MB on physical volume /dev/sdk3.  This is
       only possible if /dev/sdk3 is a member of volume group vg01  and	 there
       are enough free physical extents in it.
