[Gluster-users] Problem with creating constraints

[Uwe Weiss]

Hello List,

 

I have a problem in creating a constraint. I hope that someone could help me
and give me a hint.

 

I have three resources (A,B,C) and two cluster nodes (node0,node1). Resource
A can run only on node0 and resource B can run only node1.

I managed this by resource-stickiness INFINITY for each resource.

 

Resource C can run on both nodes but  on node0 only if resource A is up and
running or on node 1 if resource B is up and running.

Additionally resource C can only start after resource A or B

 

How do I have to create resource order constraints and resource location
constraints that meets the requirement of resource C

 

Thx in advance

Uwe
