Ok, I have installed latest version of pacemaker (1.0.5) from opensuse
ha-clustering repo, but it is not working.
I'm starting openais on the alpha node and i get a lot of messages. On the
bravo node openais fails to start.
The same happens if i start the bravo node first, the on alpha it fails.
Attached is my log. At least it doesn't segfault!
I'm starting to get tired. And with pacamaker 1.0.1 my only problem was the
order constraint.
I have also cleared all the configurations (cib.xml and others in
/var/lib/heartbeat/crm) to start from scratch without success.
Any help is appreciated. I'm feeling lost.
Thanks in advance.
