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=1 on all resources .
What I want it that if I have a failure for example on Res3 is that all the 5 Ressources are migrated.
Is there a solution ?
For example , with an HA LVM configuration and VM resources :
Res1=VGA
Res2=FS-img-VM1 (where are the VM1 image and .xml) (FS-img-VM1 is on VGA LV)
Res3=VM1
Res4=FS-img-VM2 (where are the VM2 image and .xml) (FS-img-VM1 is on another VGA LV)
Res5=VM2
So current constraints are so that VGA is activated before the FS-img is mounted 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 stalls 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
Alain Moullé
