  15 .SH DESCRIPTION
  16 pvresize resizes
  17 .I PhysicalVolume
  18 which may already be in a volume group and have active logical volumes
  19 allocated on it.
  20 .SH OPTIONS
  21 See \fBlvm\fP(8) for common options.
  22 .TP
  23 .BI \-\-setphysicalvolumesize " size"
  24 Overrides the automatically-detected size of the PV.  Use with care, or
  25 prior to reducing the physical size of the device.
  26 .SH EXAMPLES
  27 Expand the PV on /dev/sda1 after enlarging the partition with fdisk:
  28 .sp
  29 .B pvresize /dev/sda1
  30 .sp
  31 Shrink the PV on /dev/sda1 prior to shrinking the partition with fdisk
  32 (ensure that the PV size is appropriate for your intended new partition
  33 size):
  34 .sp
  35 .B pvresize \-\-setphysicalvolumesize 40G /dev/sda1
  36 .sp
  37 .SH RESTRICTIONS
  38 pvresize will refuse to shrink
  39 .I PhysicalVolume
  40 if it has allocated extents after where its new end would be. In the future,
  41 it should relocate these elsewhere in the volume group if there is sufficient
  42 free space, like
  43 .B pvmove
  44 does.
  45 .sp
  46 .B pvresize
  47 won't currently work correctly on LVM1 volumes or PVs with extra
  48 metadata areas.
