Interesting... Yet, this doesn't explain why token of 30000 causes the nodes to never assemble a cluster (waiting for half an hour, using wait_for_all=1) , while setting it to 29000 works like a charm.
Thankfully we got RH subsciption, so RH devs will provide more detailed output on the issue. I was hoping that I missed in the documentation about the maximum token size...

Knet waits for enough pong replies for other nodes before it marks them as alive and starts sending/receiving packets from them. By default it needs to receive 2 pongs and ping is sent 4 times in token timeout so it means 15 sec until node is considered up for 30 sec token timeout. > What is the maximum token value with knet ?On SLES12 (I think it was > corosync 1) , I used to set the token/consensus with far greater values on > some of our clusters.
