Yes I'm referring to the block devices. If I'm not mistaken, the major 
nb is 147 and the minor is your drbd resource number.

Oh sorry I missed that. I don't know what the default is, in doubt you 
could try 'lxc.cgroup.devices.allow = a'

If you're just testing, maybe you'll find virtual machines like VMWare 
or VirtualBox better suited. They performe slightly worse but they 
better simulate real servers.
