####################### 

In upstream Ceph documentation, it is recommended to delete cephclients.ceph.rook.io and finalizers, however in our docs is not reflected, maybe we need to update that as well to something like the following in order to troubleshoot un-installations:
~~~
for CRD in $(oc get crd  | awk '/ceph.rook.io/ {print $1}'); do co patch crd $CRD --type merge -p '{"metadata":{"finalizers": [null]}}'; done
This command will patch the following CRDs
cephblockpools.ceph.rook.io cephclients.ceph.rook.io cephfilesystems.ceph.rook.io cephnfses.ceph.rook.io cephobjectstores.ceph.rook.io cephobjectstoreusers.ceph.rook.io

for CRD in $(oc get crd  | awk '/noobaa.io/ {print $1}'); do co patch crd $CRD --type merge -p '{"metadata":{"finalizers": [null]}}'; done
backingstores.noobaa.io bucketclasses.noobaa.io noobaas.noobaa.io

for CRD in $(oc get crd  | awk '/ocs.openshift.io/ {print $1}'); do co patch crd $CRD --type merge -p '{"metadata":{"finalizers": [null]}}'; done
ocsinitializations.ocs.openshift.io  storageclusterinitializations.ocs.openshift.io storageclusters.ocs.openshift.io
~~~

In our doc it only suggests the following:
~~~
$ oc delete crd backingstores.noobaa.io bucketclasses.noobaa.io cephblockpools.ceph.rook.io cephclusters.ceph.rook.io cephfilesystems.ceph.rook.io cephnfses.ceph.rook.io cephobjectstores.ceph.rook.io cephobjectstoreusers.ceph.rook.io noobaas.noobaa.io ocsinitializations.ocs.openshift.io  storageclusterinitializations.ocs.openshift.io storageclusters.ocs.openshift.io  --wait=true --timeout=5m
~~~
