LVEXTEND(8)									      LVEXTEND(8)

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  [+]LogicalExtentsNum-
       ber[%{VG|LV|PVS|FREE}]  | -L|--size [+]LogicalVolumeSize[kKmMgGtT]} [-t|--test] [-v|--ver-
       bose] LogicalVolumePath [PhysicalVolumePath...]

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.  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}]
	      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.  The number can also be expressed as a  percent-
	      age  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,  of  the  remaining  free
	      space  for the specified PhysicalVolume(s) 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]
	      Extend 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 + 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 vol-
       ume  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.

       "lvextend /dev/vg01/lvol01 /dev/sdk3" tries to extend the size of that logical  volume  by
       the  amount  of free space on physical volume /dev/sdk3.  This is equivalent to specifying
       "-l +100%PVS" on the command line.
