I was wondering if there is any interest in adding an "on_shared_storage" field to the Instance class. This would be set once at instance creation time and we would then be able to avoid having the admin manually pass it in for the various API calls (evacuate/rebuild_instance/migration/etc.)
It could even be set automatically for the case of booting off block storage, and maybe we add a config flag indicating that a given compute node is using shared storage for its instances.
This would also allow for "nova host-evacuate" to work properly if some of the instances are on unshared storage and some are booting from block storage (which is shared). As it stands, the host-evacuate command assumes that they're all the same.
Thoughts? Chris _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
