You have etcd backup enabled in your Kubernetes cluster and need to restore from the backup due to some unforeseen circumstances.
- Platform9 Managed OpenStack - v4.1 and above
Etcd restore is an intricate procedure but the idea is to bring down master count to 1 and restore etcd from backup using etcdctl. Once that is done, we might need to make some manual changes so that it starts up as a new etcd cluster. Once things are up, we increase the master count one by one i.e. attach new nodes.
Since restoring from an etcd backup is a complicated process, we recommend involving Platform9 Support for assistance.
