Ironic upgrade now needs running online_data_migrations command
Last modified: 2017-11-08 13:50:45 EST
Ironic has implemented similar rolling upgrade procedure to Nova in https://review.openstack.org/#/c/408556/. Now we need to run one more command on upgrades, starting with Ocata->Pike (!):
Otherwise the next upgrade (Pike->Queens, for example will fail).
We need updating both undercloud and overcloud bits to run it.
