physicalvolumesizesize] PhysicalVolume [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.
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:
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
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.
