NAME
       pvresize - resize a disk or partition in use by LVM2

SYNOPSIS
       pvresize  [-d|--debug]  [-h|--help]  [-t|--test] [-v|--verbose] [--version] [--setphysicalvolumesize size] PhysicalVolume
       [PhysicalVolume...]

DESCRIPTION
       pvresize resizes PhysicalVolume which may already be in a volume group and have active logical volumes allocated on it.

OPTIONS
       See lvm(8) for common options.

       --setphysicalvolumesize size
              Overrides the automatically-detected size of the PV.  Use with care, or prior to reducing the physical size of the
              device.

EXAMPLES
       Expand the PV on /dev/sda1 after enlarging the partition with fdisk:

       pvresize /dev/sda1

       Shrink  the  PV on /dev/sda1 prior to shrinking the partition with fdisk (ensure that the PV size is appropriate for your
       intended new partition size):

       pvresize --setphysicalvolumesize 40G /dev/sda1


RESTRICTIONS
       pvresize will refuse to shrink PhysicalVolume if it has allocated extents after where  its  new  end  would  be.  In  the
       future, it should relocate these elsewhere in the volume group if there is sufficient free space, like pvmove does.

       pvresize won't currently work correctly on LVM1 volumes or PVs with extra metadata areas.
