Advice on encrypted storage - Lemmy.World

I currently have a storage server with the following config. Multiple raid6 volumes (mdadm) -> aggregated into a lvm volume group -> lvm volumes -> encrypted with luks1 -> (no partitioning) xfs file systems mounted and used by the os I have the following criteria: I want to keep software raid (mdadm) with multiple raid sets, xfs, and lvm. I don’t mind using 2fa, but I don’t want to just store my secret keys on a dongle attached to my PC because that seems to defeat the point of encryption at rest. My questions: 1. Is there a better way to encrypt my data at rest? 2. Is there a better layer at which to apply the encryption? I’m mostly unhappy with luks1 over a whole lvm volume and looking for alternatives.
