Expanding a LUKS partition to a second drive.

[James Dehnert <zeke.dehnert@xxxxxxxxxxxxx>]

Greetings dm-crypt group,

I have a situation where I have an existing LUKS encrypted partition (root) and the user wants to expand that partition onto a second drive.

The existing partition was created at configuration as part of the Ubuntu preseed setup.

I know how to do this with LVM, but I'm not sure if this can be done without backing up all the data, and then rebuilding the system from scratch.

I'm not sure where the LUKS volume is created in respect to LVM.  I can't tell if its created directly on the physical volume, on the volume group, or on the logical volume, so I'm noy sure where I should be looking to expand the substrate.  Or if this is even possible.

Any assistance would be greatly appreciated, even if its just "It can't be done".
