OK, so you're talking about VM resurrections within OpenStack, via
the misnamed[0] "nova evacuate" API.

I agree - much more info required here, including cluster
configuration and the current state of resources (e.g. output of
crm_mon).

I am the upstream maintainer of the openstack-resource-agents project
which includes NovaEvacuate[1], so I will try to help if you can
provide enough information.  Although I suspect you are probably using
a vendor-provided version of NovaEvacuate and related files, is that
right?  If so, you might be better off obtaining support from that
vendor.
