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
dont do that
write a proper agent for whateverdaemond (maybe you can use an init-
script instead)
add a clone resource for mysql
add a clone resource for whateverdaemond
colocate whateverdaemond with mysql
colocate R1 with mysql
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.

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.
