I think you would need to allow access from your LXC to DRBD's major/minor device numbers, and maybe the low-level devices' ones too (not sure about that last one). Out of curiosity, may I ask for some details about what you're trying to achieve? In case it helps to kown that, we've been doing it the other way round (LXCs inside DRBD containers) with little difficulty. Lionel Sausin.
