Hi all, I was testing the corosync cluster engine by using the testcpg exec provided along with the release. I am getting the below behaviour while testing some specific scenarios. Kindly comment on the expected behaviour.
1) 3 Node cluster 1---------2---------3 a) suppose I bring the nodes 1&2 up, it will form a ring (1,2) b) now bring up 3 c) 3 sends join which restarts the membership process d) (1,2) again forms the ring , 3 forms self cluster e) now 3 sends a join (due to join or other timeout) f) again membership protocol is started as 2 responds to this by going to gather state ( i believe 2 should not accept this as 2 would have earlier decided that 3 is failed) I am seeing a continuous loop of the above behaviour ( operational -> membership -> operational -> ) due to which the cluster is not becoming stabilized 2) 3 Node Cluster 1---------2-----------3 a) bring up all the three nodes at the same time (None of the nodes have seen each other before this) b) Now each node forms a cluster by itself .. (Here i think it should from either a (1,2) or (2,3) ring ) Regards, Ranjith
