3.2.2. Adding Unallocated Volumes to a Volume Group
Once initialized, a volume will be listed in the 'Unallocated Volumes' list. The figure below illustrates an unallocated partition (Partition 3). The respective buttons at the bottom of the window allow you to:
create a new volume group,
add the unallocated volume to an existing volume group,
remove the volume from LVM.
To add the volume to an existing volume group, click on the Add to Existing Volume Group
Once added to an existing volume group the new logical volume is automatically added to the unused space of the selected volume group. You can use the unused space to:
create a new logical volume (click on the Create New Logical Volume(s) button,
select an existing logical volume and remove it from the volume group by clicking on the Remove Selected Logical Volume(s) button. Please note that you cannot select unused space to perform this operation.
The figure below illustrates the logical view of 'VolGroup00' after adding the new volume group.
In the figure below, the uninitialized entities (partitions 3, 5, 6 and 7) were added to 'VolGroup00'.
