commit c3118b91db4b97a689c9a2f25a9554a0ccb29252 Author: EdLeafe <[email protected]> Date: Wed Jul 26 23:07:38 2017 +0000 Handle addition of new nodes/instances in ironic flavor migration The original idea for ironic flavor migration was to handle it in init_host(), so that the code wouldn't run often. But in a situation like an upgrade with multiple Nova computes handling ironic nodes, this may not cover all the nodes, so we are moving it to be run whenever the cache is refreshed, and new nodes for the compute service that have instances are detected. We also need to cover the cases where an existing node has a new instance created on it to ensure that that new instance's flavor is also migrated.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1707021 Title: Ironic Flavor Migration can miss instances Status in OpenStack Compute (nova): Fix Released Status in OpenStack Compute (nova) pike series: Fix Released Bug description: The recently merged patch (https://review.openstack.org/484949) runs the migration in the driver's init_host() method. It has since been pointed out that if there are multiple computes handling ironic, some instances can get skipped if the hash ring is refreshed and an unmigrated instance is placed on a compute whose init_host has already run. While a rare thing, this should be corrected to ensure that all instances have their flavors migrated in Pike.
