Does anyone have a proper working Configuration Percona Server for MongoDB cross-site replication for OpenShift? Perhaps something in GitHub or Gist? The current documentation is very vague. Any help us appreciated. ---

Hi @Wayne_Dovey, Apart from the docs we have two blog posts: > **[Migrating MongoDB to Kubernetes - Percona Database Performance Blog](https://www.percona.com/blog/migrating-mongodb-to-kubernetes)** > > Migrating MongoDB to Kubernetes is a challenging task, but it is much simpler with Percona Distribution for MongoDB Operator. > **[Disaster Recovery for MongoDB on Kubernetes - Percona Database Performance Blog](https://www.percona.com/blog/disaster-recovery-for-mongodb-on-kubernetes)** > > How to set up MongoDB on two distant Kubernetes clusters with Percona Distribution for MongoDB Operator to meet the toughest DR requirements. They’re not specific to Openshift but they may help. If you have any specific problems, please let us know. ---

Magic! Thanks mate. I have tried the config but I now get the following error on all our my replica site nodes. Any ideas? ``` "_id" : 5, "name" : "172.132.89.162:27017", "health" : 0, "state" : 8, "stateStr" : "(not reachable/healthy)", "uptime" : 0, "optime" : { "ts" : Timestamp(0, 0), "t" : NumberLong(-1) }, "optimeDurable" : { "ts" : Timestamp(0, 0), "t" : NumberLong(-1) }, "optimeDate" : ISODate("1970-01-01T00:00:00Z"), "optimeDurableDate" : ISODate("1970-01-01T00:00:00Z"), "lastHeartbeat" : ISODate("2021-11-04T11:52:29.249Z"), "lastHeartbeatRecv" : ISODate("1970-01-01T00:00:00Z"), "pingMs" : NumberLong(0), "lastHeartbeatMessage" : "replica set IDs do not match, ours: 6183c202955df555e0b64ce0; remote node's: 6183c398459fbd2de4645c09", ``` ---

Could you please share the cr.yaml for each environment? If I have to guess I’d say you haven’t deployed the cluster with `unmanaged: true` in the replica side. ---

The configs look OK to me but the error you posted before means two cluster has their own ReplicaSet. When you deploy an unmanaged cluster, the operator won’t create a replica set config and just wait it to be configured externally. ---

So no luck. Do you know if the AWS Loadbalancer works? my replicas seem to be unhealthy ``` { "_id" : 3, "name" : "a4152077f49044a6381e3870fae3e9be-1830102077.ap-southeast-2.elb.amazonaws.com:27017", "health" : 0, "state" : 6, "stateStr" : "(not reachable/healthy)", "uptime" : 0, "optime" : { "ts" : Timestamp(0, 0), "t" : NumberLong(-1) }, "optimeDurable" : { "ts" : Timestamp(0, 0), "t" : NumberLong(-1) }, "optimeDate" : ISODate("1970-01-01T00:00:00Z"), "optimeDurableDate" : ISODate("1970-01-01T00:00:00Z"), "lastHeartbeat" : ISODate("2021-11-05T12:44:41.289Z"), "lastHeartbeatRecv" : ISODate("1970-01-01T00:00:00Z"), "pingMs" : NumberLong(0), "lastHeartbeatMessage" : "", "authenticated" : false, "syncSourceHost" : "", "syncSourceId" : -1, "infoMessage" : "", "configVersion" : -1, "configTerm" : -1 }, { "_id" : 4, "name" : "a74b438bcf55847da88acf544445b946-790054600.ap-southeast-2.elb.amazonaws.com:27017", "health" : 0, "state" : 6, "stateStr" : "(not reachable/healthy)", "uptime" : 0, "optime" : { "ts" : Timestamp(0, 0), "t" : NumberLong(-1) }, "optimeDurable" : { "ts" : Timestamp(0, 0), "t" : NumberLong(-1) }, "optimeDate" : ISODate("1970-01-01T00:00:00Z"), "optimeDurableDate" : ISODate("1970-01-01T00:00:00Z"), "lastHeartbeat" : ISODate("2021-11-05T12:44:43.130Z"), "lastHeartbeatRecv" : ISODate("1970-01-01T00:00:00Z"), "pingMs" : NumberLong(0), "lastHeartbeatMessage" : "", "authenticated" : false, "syncSourceHost" : "", "syncSourceId" : -1, "infoMessage" : "", "configVersion" : -1, "configTerm" : -1 }, { "_id" : 5, "name" : "a0a49c3809d5345a986d4d41fc88f03d-638471580.ap-southeast-2.elb.amazonaws.com:27017", "health" : 0, "state" : 6, "stateStr" : "(not reachable/healthy)", "uptime" : 0, "optime" : { "ts" : Timestamp(0, 0), "t" : NumberLong(-1) }, "optimeDurable" : { "ts" : Timestamp(0, 0), "t" : NumberLong(-1) }, "optimeDate" : ISODate("1970-01-01T00:00:00Z"), "optimeDurableDate" : ISODate("1970-01-01T00:00:00Z"), "lastHeartbeat" : ISODate("2021-11-05T12:44:41.598Z"), "lastHeartbeatRecv" : ISODate("1970-01-01T00:00:00Z"), "pingMs" : NumberLong(0), "lastHeartbeatMessage" : "", "authenticated" : false, "syncSourceHost" : "", "syncSourceId" : -1, "infoMessage" : "", "configVersion" : -1, "configTerm" : -1 } ], ``` ---
