If you want to take a disk out of service it must first have all of its active physical extents moved to another disk. This disk must be an LVM physical volume in the
same volume group as the disk to be removed and have enough free space to hold the extents to be copied from the old disk. For further detail see Removing an old
disk.

The following command moves all the data from the IDE disk partition /dev/hdb1 onto a SCSI disk partition /dev/sdg1. Be aware that this command can take a
considerable amount of time to complete.

Also, if the extents contain a striped logical volume then the process cannot be interrupted so it is strongly recommended that you take a backup of your data before
starting pvmove.

# pvmove /dev/hdb1 /dev/sdg1
