Question around resources constraints (pacemaker on RHE7.1)

Hi

I can't find a way to configure constraints in pacemaker so that with these=
 resources:

Res1
Res2
Res3
Res4
Res5

with current colocation constraints :
Res2 with Res1
Res3 with Res2

Res4 with Res1
Res5 with Res4

and current order symmetrical constraints :
Res2 after Res1
Res3 after Res2

Res4 after Res1
Res5 after Res4

and migration-threshold=3D1 on all resources .

What I want it that if I have a failure for example on Res3  is that all th=
e 5 Ressources are migrated.

Is there a solution ?

For example , with an HA LVM configuration and VM resources :

Res1=3DVGA
Res2=3DFS-img-VM1 (where are the VM1 image and .xml) (FS-img-VM1 is on VGA =
LV)
Res3=3DVM1
Res4=3DFS-img-VM2 (where are the VM2 image and .xml) (FS-img-VM1 is on anot=
her VGA LV)
Res5=3DVM2

So current constraints are so that VGA is activated before the FS-img is mo=
unted and before the VM is started.

But I want that if the VM1 fails, it can migrate on another node (together =
with all other 4 resources) but with only the constraints above, the VGA st=
alls the migration of the VM ...

Is there any solution by constraints configuration ?
Note : we can't use group resources for now, because VMs are remote-nodes.

Thanks
