+#### Troubleshooting Rook-Ceph installation
+
+In case your machine had rook previously installed successfully or unsuccessfully
+and you are attempting a fresh installation of rook operator, you may face some issues.
+Lets help you with that.
+
+* First check if there are some rook CRDs existing :
+```
+kubectl get crds | grep rook
+```
+If this return results like :
+```
+otc@otconap7 /var/lib/rook $ kc get crds | grep rook
+cephblockpools.ceph.rook.io 2019-07-19T18:19:05Z
+cephclusters.ceph.rook.io 2019-07-19T18:19:05Z
+cephfilesystems.ceph.rook.io 2019-07-19T18:19:05Z
+cephobjectstores.ceph.rook.io 2019-07-19T18:19:05Z
+cephobjectstoreusers.ceph.rook.io 2019-07-19T18:19:05Z
+volumes.rook.io 2019-07-19T18:19:05Z
+```
+then you should delete these previously existing rook based CRDs by generating a delete
+manifest file by these commands and then deleting those files:
+```
+helm template -n rook . -f values.yaml > ~/delete.yaml
+kc delete -f ~/delete.yaml
+```
+
+After this, delete the below directory in all the nodes.
+```
+sudo rm -rf /var/lib/rook/
+```
+Now, again attempt :
+```
+helm install -n rook . -f values.yaml --namespace=rook-ceph-system
+```
+
#### Install Operator package
```bash
cd $DA_WORKING_DIR/operator
helm install -n minio . -f values.yaml --namespace=edge1
```
+#### Onboard messaging platform
+
+We have currently support strimzi based kafka operator.
+Navigate to ```$DA_WORKING_DIR/deploy/messaging/charts/strimzi-kafka-operator``` directory.
+Use the below command :
+```
+helm install . -f values.yaml --name sko --namespace=test
+```
+
+NOTE: Make changes in the values.yaml if required.
+
+Once the strimzi operator ready, you shall get a pod like :
+
+```
+strimzi-cluster-operator-5cf7648b8c-zgxv7 1/1 Running 0 53m
+```
+
+Once this done, install the kafka package like any other helm charts you have.
+Navigate to dir : ```$DA_WORKING_DIRdeploy/messaging``` and use command:
+```
+helm install --name kafka-cluster charts/kafka/
+```
+
+Once this done, you should have the following pods up and running.
+
+```
+kafka-cluster-entity-operator-b6557fc6c-hlnkm 3/3 Running 0 47m
+kafka-cluster-kafka-0 2/2 Running 0 48m
+kafka-cluster-kafka-1 2/2 Running 0 48m
+kafka-cluster-kafka-2 2/2 Running 0 48m
+kafka-cluster-zookeeper-0 2/2 Running 0 49m
+kafka-cluster-zookeeper-1 2/2 Running 0 49m
+kafka-cluster-zookeeper-2 2/2 Running 0 49m
+```
+
+You should have the following services when do a ```kubectl get svc```
+
+```
+kafka-cluster-kafka-bootstrap ClusterIP 10.XX.YY.ZZ <none> 9091/TCP,9092/TCP,9093/TCP 53m
+kafka-cluster-kafka-brokers ClusterIP None <none> 9091/TCP,9092/TCP,9093/TCP 53m
+kafka-cluster-zookeeper-client ClusterIP 10.XX.YY.ZZ <none> 2181/TCP 55m
+kafka-cluster-zookeeper-nodes ClusterIP None <none> 2181/TCP,2888/TCP,3888/TCP 55m
+```
+#### Testing messaging
+
+You can test your kafka brokers by creating a simple producer and consumer.
+
+Producer :
+```
+kubectl run kafka-producer -ti --image=strimzi/kafka:0.12.2-kafka-2.2.1 --rm=true --restart=Never -- bin/kafka-console-producer.sh --broker-list kafka-cluster-kafka-bootstrap:9092 --topic my-topic
+ ```
+ Consumer :
+ ```
+
+kubectl run kafka-consumer -ti --image=strimzi/kafka:0.12.2-kafka-2.2.1 --rm=true --restart=Never -- bin/kafka-console-consumer.sh --bootstrap-server kafka-cluster-kafka-bootstrap:9092 --topic my-topic --from-beginning
+```
+
