Dear Team, I already installed one controller and 2 compute node with 3 ceph node with rdo openstack kilo version. And ceph & openstack both are integrated with each other and glance,cinder vm all use ceph as backend. In 2 compute node I create 2 instances in each . But suppose my one compute node is crashed then in that case what about my instances ? and how I safely recover my 2 instances and restore in other compute node ? Plz explain it . How it is possible ?
