I try to be more explicit.
I use v2 configuration
I got 2 servers A and B. A set (group) of resource R1.
R1 is running by default on server A and jump to server B in case of
trouble.
This is currently setup and working fine.
Now, i need to check mysql running on both server A and B.
If mysql isn't ok on server running R1, I need to stop whateverdaemond
and move R1 to the other server
If mysql isn't ok on server not running R1, I just need to stop
whateverdaemond.
I made a OCF agent that does the "stop whateverdaemond if mysql is down" job
This where I get puzzled, how to translate the relation between the "if
running R1" and the agent I wrote it in heartbeat groups and constraints
Hope it's clearer.
Franck.

Hi,
I have a two 2 node cluster.
group1 is active/passive set of ressource.
group1 is currently hop-ing from one node to the other as intended when
one of the group ressource isn't available.
Now I have a second task for heartbeat.
On each node, I have a mysql server, if it goes wrong, I must shutdown a
service and migrate the group1 (if it runs on this node) to the other node.
And this something I don't know how to do.
I was thinking about creating a group2 in an active/active configuration
testing mysql and if goes wrong just shutdown the service in the stop
process of the group2 but I don't know how to force in this case the
push of the group1 to the other node of it's running on the group2
failing node.
Sorry, but I can't follow. Can you please rephrase.
Which configuration do you use: v1 or v2?
Thanks,
Dejan
Any one can help me?
Hope it's clear.
Franck.
