If my compute node down, could the instance on this node move to other nodes?</span></p></div></div></blockquote><div>This wouldn't specifically be OSA as such - the configuration side of it could be set up by OSA, such as configuration options, shared storage required. However the automatic evacuation of instances, or migration of instances wouldn't be handled by OSA or anything that OSA deploys.</div><div><br></div><div>I hope that helps! If you have any more questions, or need further help getting set up with OSA feel free to drop by the #openstack-ansible channel on Freenode IRC.</div><div><br></div><div>Thanks!</div><div>Andy</div></div></div></div>
