1. Verify the volume group and the logical volume name:


2. Add a new hard disk device to add to the volume group (in this example /dev/sdd):

pvcreate /dev/sdd
vgextend existing_volume_group /dev/sdd

3. After extending the volume group, extend the underlying Logical Volume (500GB):

sudo lvextend -L+500G /dev/existing_volume_group/logicalvolume_data

sudo cryptsetup resize /dev/mapper/

5. Resize filesystem:

sudo resize2fs /dev/mapper/
