| .RI [ PhysicalVolume ...] |
| .SH DESCRIPTION |
| pvresize resizes |
| .I PhysicalVolume |
| which may already be in a volume group and have active logical volumes |
| allocated on it. |
| .SH OPTIONS |
| See \fBlvm\fP(8) for common options. |
| .TP |
| .BI \-\-setphysicalvolumesize " size" |
| Overrides the automatically-detected size of the PV. Use with care, or |
| prior to reducing the physical size of the device. |
| .SH EXAMPLES |
| Expand the PV on /dev/sda1 after enlarging the partition with fdisk: |
| .sp |
| .B pvresize /dev/sda1 |
| .sp |
| 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): |
| .sp |
| .B pvresize \-\-setphysicalvolumesize 40G /dev/sda1 |
| .sp |
| .SH RESTRICTIONS |
| pvresize will refuse to shrink |
| .I 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 |
| .B pvmove |
| does. |
| .sp |
| .B pvresize |
| won't currently work correctly on LVM1 volumes. |
