Fixed In Version:	openstack-nova-2014.1.3-10.el7ost
Doc Type:	Bug Fix
Doc Text:	Previously, the evacuate function did not consider RBD storage as shared and the evacuate procedure failed with RBD-backed instances. With this fix, RBD storage is now marked as shared, and the evacuate function handles the shared storage attribute and therefore now operates on RBD.

Comment 5 Yogev Rabl 2015-04-12 05:01:57 EDT

I'm not sure about how the system defines a failed compute. 
The scenario I've tested is: 
1. stopped the services openstack-nova-compute or libvirtd
2. tried to evacuate an instance 
With both options the system response to the evacuation was: 
ERROR: Compute service of <host name> is still in use. 

Eoghan, How can I change the status of the Compute?

Comment 6 Pádraig Brady 2015-04-13 07:38:27 EDT

Please ensure the openstack-nova-api service is stopped

Comment 7 Eoghan Glynn 2015-04-13 08:25:51 EDT

After discussing on IRC, the conclusion is:

 * nova-api service should not be shut down, as the POST /v2/{tenant_id}/servers/{server_id}/evacate call must be mediated by the service for each VM on the old node

 * shutting down nova-compute service should suffice, but in realistic example reproducing this issue, the entire compute node was powered-down
