15 | .SH DESCRIPTION |
| 16 | .B pvresize | |
| 17 | resizes | |
| 18 | .I PhysicalVolume | |
| 19 | which may already be in a volume group and have active logical volumes | |
| 20 | allocated on it. | |
| 21 | .SH OPTIONS | |
| 22 | See \fBlvm\fP(8) for common options. | |
| 23 | .TP | |

25 | Overrides the automatically-detected size of the PV. Use with care, or |
| 26 | prior to reducing the physical size of the device. | |
| 27 | .SH EXAMPLES | |
| 28 | Expand the PV on /dev/sda1 after enlarging the partition with fdisk: | |
| 29 | .sp | |
| 30 | .B pvresize /dev/sda1 | |
| 31 | .sp | |
| 32 | Shrink the PV on /dev/sda1 prior to shrinking the partition with fdisk | |
| 33 | (ensure that the PV size is appropriate for your intended new partition | |
| 34 | size): | |
| 35 | .sp | |
| 36 | .B pvresize --setphysicalvolumesize 40G /dev/sda1 | |
| 37 | .sp | |
| 38 | .SH RESTRICTIONS | |
| 39 | .B pvresize | |
| 40 | will refuse to shrink | |
| 41 | .I PhysicalVolume | |
| 42 | if it has allocated extents after where its new end would be. In the future, | |
| 43 | it should relocate these elsewhere in the volume group if there is sufficient | |
| 44 | free space, like | |
| 45 | .B pvmove | |
| 46 | does. | |
| 47 | .sp | |
| 48 | .B pvresize | |
| 49 | won't currently work correctly on LVM1 volumes or PVs with extra | |
| 50 | metadata areas. | |
