Extend encrypted LVM By adding new physical disk
1. Verify the volume group and the logical volume name:
pvdisplay
lvdisplay
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
4. Resize the Crypt:
sudo cryptsetup resize /dev/mapper/
5. Resize filesystem:
sudo resize2fs /dev/mapper/
