Hmpf. All pacemaker processes start but leave without trace soon:
Oct 14 16:22:44 alpha cib: [18888]: info: startCib: CIB Initialization completed successfully
Oct 14 16:22:44 alpha cib: [18888]: info: crm_cluster_connect: Connecting to OpenAIS
Oct 14 16:22:44 alpha cib: [18888]: info: init_ais_connection: Creating connection to our AIS plugin
That's the last we hear from cib. Unfortunately that's too little
to work on. Maybe they are segfaulting. Can you please check
again /var/lib/heartbeat/cores
Perhaps somebody else has an idea on what's going on.
THanks,
Dejan
