I will certainly concede that "Timer expired” isn’t a very helpful error, however based on:

Apr 23 03:13:43 server1 cib[11920]:    error: cib_process_request: Operation ignored, cluster configuration is invalid. Please repair and restart: Update does not conform to the configured schema 

I can say that you are getting it because the _current_ contents is invalid.
What does /var/lib/pacemaker/cib/cib.xml 'cibadmin -Ql’ show?
