I want to access my user-partition from a client, so that it can encrypt the saved data without the server knowing the key, therefore the client doesn't have to trust it. Diagram:
Layer5: Filesystem | btrfs | Client Layer4: Encryption | LUKS | Client Layer3: Transport ? Layer2: Partitions | user-part |server-part| Server Layer1: RAID | mdadm RAID5 6TB | Server Layer0: HW: | 3TB | 3TB | 3TB | Server
But I don't know how to access the partition. I tried NBD, but any documentation of it is outdated, so I can't get it working. Are there alternatives to NBD?
