NetBSD 6.1.5 - man page for lvresize (netbsd section 8)

LVRESIZE(8)									      LVRESIZE(8)

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

DESCRIPTION
       lvresize allows you to resize a logical volume.	Be careful when reducing a  logical  vol-
       ume'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  mir-
       rored 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)
