One of my friends recently installed a new storage server in our shared lab environment and graciously gave me some storage space on it via iSCSI. I use Proxmox for my personal lab, and I intended to store some non-critical VM disks on this new storage so I could play around with properly using HA (High Availability) with Proxmox. Additionally, I wanted to gain some experience using iSCSI at the same time. While I trust my friend, the storage itself is outside of my control, so I figured it would be good practice to encrypt my data. The general go-to solution for this would seem to be LUKS.
