I just bought a 2 TB hard disk because the home partition on the old one is almost full.

What I want to do is to extend the home partition on hard disk 1 (sda2) to also include all the space on the new hard disk (sdb1). This seemed rather straight forward at first, however there's one issue. My home-partition is LUKS-encrypted.

How do I extend sda2 to also span over sdb1 and act as one single partition? My initial thought was to create a logical volume (merging sda2 and sdb1), however I wasn't able to find a guide with a scenario like my own. Any ideas?

fdisk -l output:
