Hi,
after quite some time I want to start developing again. Is there any help and
example how to use the corosync / pacemaker APIs?
Especially I would like to find out how many nodes are in a cluster and how
many nodes are online. Perhaps somebody could post a code snipplet here.
Thanks.

I think you might find the crm_mon.c source code useful for this.

Looks like something wrong with the pacemaker installation.

Thank you for the fast reply!
Personally I do not think that starting of the service is
the issue.
May be I missed it in the documentation.
According to my understanding, all resources added to Pacemaker
are added as managed and monitored resources.
Can I configure a resource to be only a m

Hi Andrew,
can you tell me what the attribute #uname is holding?
Is it the node-name or the 'uname -n' of the node?
(I justt read
http://clusterlabs.org/doc/en-US/Pacemaker/1.1-plugin/html-single/Pacemaker_
Explained/index.html#_which_resource_instance_is_promoted)
Is there an attribute like '#n
