       pvresize — resize a disk or partition in use by LVM2


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


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


       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.


       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


       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.
