Resizing & Removing Physical Volumes
If you need to change the size of an underlying block device for any reason, use the pvresizecommand to update LVM with the new size. You can execute this command while LVM is using the physical volume.
If a device is no longer required for use by LVM, you can remove the LVM label with the pvremovecommand. Executing the pvremove command zeroes the LVM metadata on an empty physical volume. If the physical volume you want to remove is currently part of a volume group, you must remove it from the volume group with the vgreduce command.
# pvremove /dev/sdd5
