Here is my corosync log
My question is:
- Why each node has their own DC, node1 detects two nodes while node2 show only one?
- What can be problem make two node can't join cluster?
- Can we make pacemaker+corosync between Centos 5 and Centos 6?
Here is my software version in two node:
Node1: - Corosync version 1.4.3 - Pacemaker version 1.1.8-2.el5 - Centos release 5.8 (Final)
Node2: - Corosync version 1.4.1 - Pacemaker version 1.1.8-7.el6 - Centos release 6.4 (Final)
UPDATE When I configured the first time, everything worked ok. After I shutdown node 1, turn on it to test failover case, this problem occured.
