Been new to pacemaker, Im trying to create my first cluster of two nodes, but
it seems to behave a little strange.
Following this guide: http://clusterlabs.org/quickstart-redhat-6.html
<http://clusterlabs.org/quickstart-redhat-6.html>
but am unable to do f.ex.:
[root@afnA ~]# pcs property set stonith-enabled=false
Error: Unable to update cib
Call cib_replace failed (-62): Timer expired
only thing I find in logs are continued corosync events:
Nov 06 01:30:54 corosync [TOTEM ] Retransmit List: 96 97
Nov 06 01:30:56 corosync [TOTEM ] Retransmit List: 96 97
Nov 06 01:30:57 corosync [TOTEM ] Retransmit List: 96 97
Nov 06 01:30:59 corosync [TOTEM ] Retransmit List: 96 97
Nov 06 01:31:01 corosync [TOTEM ] Retransmit List: 96 97
This means something is blocking successful delivery of packets. Make
sure to:
- Properly configure firewall (for testing you can disable it completely)
- Make sure you have properly configured multicast. As alternative, you
can try udpu. Udpu is usually better compatible with switches and for
two node use case performance is same.

Let me known if more info would help!
