excellent

I already try it with 3 node test cluster.


I try 2 nodes with ver:1 and one with ver:0 - ver:0 stays offline. 
And i try vise-versa - 2 with ver:0 and 1 with ver:1 - ver:1 stays offline
I post this on #linix-cluster IRC and check it with danfrincu. 



Hm, ok I have some time before production start and make test again to send you logs.
