That's right...you do not have to wait.  Besides, think about how a cluster is brought up initially...first node, then the other nodes in rapid succession.  If I may ask, where/from whom did you get the idea that you had to wait?  Just curious...  Cheers Rob
Hello ...  Does anybody know how to add more than one nodes to cluster ?  I found how to in the case of one node ... but not for 2 ....   The thing is that I would like to know whether we need to wait for rebalaning (  Isilon custer will automatically start to rebalance data across the available cluster nodes ) to be finished before adding another node or not ..     thanks !
