* Previously, as a cluster administrator, if tried to add or remove storage from an Elasticsearch cluster, the OpenShift Elasticsearch Operator (EO) incorrectly tried to upgrade the Elasticsearch cluster, displaying `scheduledUpgrade: "True"`, `shardAllocationEnabled: primaries`, and the change volumes. The current release fixes this issue, so the EO does not try to upgrade the Elasticsearch cluster.
+
The EO status displays the following new status information to indicate when you have tried to make an unsupported change to the Elasticsearch storage that it has ignored:
+
- `StorageStructureChangeIgnored` when you try to change between using ephemeral and persistent storage structures.
- `StorageClassNameChangeIgnored` when you try to change the storage class name.
- `StorageSizeChangeIgnored` when you try to change the storage size.

[NOTE]
====
If you configure the `ClusterLogging` custom resource (CR) to switch from ephemeral to persistent storage, the EO creates a persistent volume claim (PVC) but does not create a persistent volume (PV). To clear the `StorageStructureChangeIgnored` status, you must revert the change to the `ClusterLogging` CR and delete the persistent volume claim (PVC).

Description of problem:

Deploy logging, don't enable storage for ES, after all ES pods running, add storage to ES, then the ES cluster upgrade status becomes `scheduledUpgrade: "True"`, and `shardAllocationEnabled` is set to `primaries`:

Version-Release number of selected component (if applicable):

elasticsearch-operator.5.1.0-20
How reproducible:

Always
Steps to Reproduce:

condition 1:

1. deploy CLO and EO
2. create cl/instance with

  logStore:
    type: "elasticsearch"
    retentionPolicy: 
      application:
        maxAge: 60h 
      infra:
        maxAge: 3h
      audit:
        maxAge: 1d
    elasticsearch:
      nodeCount: 3
      redundancyPolicy: "SingleRedundancy"
      resources:
        requests:
          memory: "2Gi"
      storage: {}

3. wait until ES cluster status becomes green, update cl/instance, add storage to ES:

  logStore:
    type: "elasticsearch"
    retentionPolicy: 
      application:
        maxAge: 60h 
      infra:
        maxAge: 3h
      audit:
        maxAge: 1d
    elasticsearch:
      nodeCount: 3
      redundancyPolicy: "SingleRedundancy"
      resources:
        requests:
          memory: "2Gi"
      storage:
        storageClassName: "gp2"
        size: "20Gi"

4. check ES status in es/elasticsearch

condition 2:

1. deploy CLO and EO
2. create cl/instance with

  logStore:
    type: "elasticsearch"
    retentionPolicy: 
      application:
        maxAge: 60h 
      infra:
        maxAge: 3h
      audit:
        maxAge: 1d
    elasticsearch:
      nodeCount: 3
      redundancyPolicy: "SingleRedundancy"
      resources:
        requests:
          memory: "2Gi"
      storage: 
        storageClassName: "gp2" 
        size: "20Gi"

3. wait until ES cluster status becomes green, update cl/instance, remove storage :

  logStore:
    type: "elasticsearch"
    retentionPolicy: 
      application:
        maxAge: 60h 
      infra:
        maxAge: 3h
      audit:
        maxAge: 1d
    elasticsearch:
      nodeCount: 3
      redundancyPolicy: "SingleRedundancy"
      resources:
        requests:
          memory: "2Gi"
      storage: {}

4. check ES status in es/elasticsearch

Actual results:

No ES pod restarts, but the ES cluster `upgradeStatus` is changed to `scheduledUpgrade: "True"`

No message `Changing the storage structure for a custom resource is not supported` when follow the steps in condition 1.

Expected results:

ES cluster should not in upgrade status, and in es/elasticsearch, there should have message like:

    conditions:
    - lastTransitionTime: "2021-05-07T01:05:13Z"
      message: Changing the storage structure for a custom resource is not supported
      reason: StorageStructureChangeIgnored
      status: "True"
      type: StorageStructureChangeIgnored

Additional info:

is documented by

RHDEVDOCS-3018 Document: [Logging 5.1]EO shouldn't try to upgrade ES cluster after adding/removing storage.
