Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


Though Both nodes have the exact same configuration and reachable,
low-level storage connected, and mounted, and both server reachable,

I still cannot create the device metadata (from either nodes)
*sudo drbdadm create-md r0*
'r0' not defined in your config (for this host).

Any hint?
