Hi James, to be safe, you need to do this with a full backup of the data in the LUKS container anyways. Hence easisest is probably backup->make new partition->restore. The LUKS container itself has no size information, it will fill the new parition. For the filesystem, you need to either backup the LUKS container as ibinary mage and extend the filesystem in it after restore, or backup on file-level and create a new LUKS container and filesystem in it. Luks does nto care whther the partition is native or LVM (or NBD, or whatever).
