| 18 | which may already be in a volume group and have active logical volumes | |
| 19 | allocated on it. | |
| 20 | .SH OPTIONS | |

24 | Overrides the automatically-detected size of the PV. Use with care, or |
| 25 | prior to reducing the physical size of the device. | |
| 26 | .SH EXAMPLES | |
| 27 | Expand the PV on /dev/sda1 after enlarging the partition with fdisk: | |
| 28 | .sp | |
| 29 | .B pvresize /dev/sda1 | |
| 30 | .sp | |
| 31 | Shrink the PV on /dev/sda1 prior to shrinking the partition with fdisk | |
| 32 | (ensure that the PV size is appropriate for your intended new partition | |
| 33 | size): | |
| 34 | .sp | |

| c63b155d | 38 | pvresize will refuse to shrink |
| c5735ce1 AK |
39 | .I PhysicalVolume |
| 40 | if it has allocated extents after where its new end would be. In the future, | |
| 41 | it should relocate these elsewhere in the volume group if there is sufficient | |
| 42 | free space, like | |
| 43 | .B pvmove | |
| 44 | does. | |
