[Pacemaker] order constraint clone / group of primitives resources

[Björn Urbanek]

Hello!

I'm using pacemaker with crmsh. 

I want to realize the following order:

I have 3 primitive resources:
P1 
P2 
P3

I have also a cloneset of a primitive resource CL_P4. 

I want to say that one the resources of the primitive set (P1 P2 P3) is
required to start CL_P4. It doesn't mather which, only that one is started.
(P1 P2 P3) --> CL_P4
Also the cluster should always try to start all 3 primitive P1/P2/P3 per
default, but if one or two of these resources failes or have to be relocated
it should doesn't affect the CL_P4. 
Only if all of the (P1 P2 P3) resources are down or have to be relocated at
the same time CL_P4 should be affected and have to stopped and restarted.

Can anyone help me / give me a hint?

Many thanks!

Best regards

Bjoern
