Lustre uses stateful client/server connection. You don't need to - and cannot - use a virtual ip. The lustre protocol already takes care of reconnection & recovery. > The problem I'm experiencing, is that I can't seem to get the VIP listed > as a NID, thus the OSS can only connect on the real IP, which is > unwanted in this situation.

No, you have to list the nids of all the mgs nodes at mkfs time (i.e. "--mgsnode=192.168.21...@tcp --mgsnode=192.168.21...@tcp" in your case).
