I believe you can online add a third node on a 2-node cluster with you use qdiskd since the beginning, right?
This worked for me in a project where we knew in advance that we'd have a third node later on, but starting only with 2 nodes.

Provided your cluster has more than 2 nodes, this should work fine. (I
believe two node clusters are special.)
