Hi,
more information would be needed to really find out real reason, so:
- double check corosync.conf (ip addresses)
- check firewall (mainly local one)
- what is the version of corosync
- try to set debug:on (or trace)
- paste config file
- paste full log - since corosync was started
Also keep in mind if it is version 2.x it's no longer supported by
upstream and you have to contact your distribution provider support.
Regards,
Honza
