Description of problem (please be detailed as possible and provide log
snippets):
Platform: VMware LSO
Mode - Arbiter 

A version of all relevant components (if applicable):
OCP version 4.7.0-0.nightly-2021-01-05-220959
OCS version ocs-operator.v4.7.0-222.ci

Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?
yes

Is there any workaround available to the best of your knowledge?


Rate from 1 - 5 the complexity of the scenario you performed that caused this
bug (1 - very simple, 5 - very complex)?
2

Can this issue reproducible?
yes

Can this issue reproduce from the UI?
yes

If this is a regression, please provide more details to justify this:


Steps to Reproduce:

1:- Install OCP 4.7 and LSO operator (UI doesn’t support bringing up arbiter MON on Mater node yet)

2:- Label the nodes with .
topology.kubernetes.io/zone=us-east-2a and failure-domain.beta.kubernetes.io/zone=us-east-2a, see additional info for more details.

Note: Since the current OCS build does not have the new features, edited the CSV to add the following:
oc edit csv ocs-operator.v4.7.0-222.ci

Edit the enabled features to the following:
features.ocs.openshift.io/enabled: ‘[“kms”, “arbiter”, “flexible-scaling”]’

Install OCS operator 4.7.0-222.ci and click on create storage cluster
3. Select Internal -Attached mode

Sub-Steps
3a Discover Disks: -> Select Nodes: --> Select 2W nodes, each in say zone-A and zone-B (to bring up OSDs)
3b. Create Storage Class -> Provide name for SC and PVs will be created on the LSO disks
3c. Storage and the nodes -> Click on the checkbox to Enable Arbiter, select the arbiter zone (here zone: us-east-2c) and select the storageclass created in above step.
3d. Configure -> No change
3e. Review and create: review the selections and click create


Actual results:

There were no any rook pods created(mon,osd,rgw,mgr)

Snippet from rook-operator pods:-

ceph-cluster-controller: reconciling ceph cluster in namespace "openshift-storage"
2021-01-06 12:50:01.118622 I | ceph-cluster-controller: clusterInfo not yet found, must be a new cluster
2021-01-06 12:50:01.129652 E | ceph-cluster-controller: failed to reconcile. failed to reconcile cluster "ocs-storagecluster-cephcluster": failed to configure local ceph cluster: failed to perform validation before cluster creation: expecting exactly three zones for the stretch cluster, but found 5


Expected results:
There should be no error in a rook-operator pod and all rook-pods should be created
