Current setup

Description of problem:

Currently, the storage usage in the Capacity breakdown card shown is the hourly average of the values. It should be an absolute value.

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


How reproducible:


Steps to Reproduce:
1. Create an OCS setup.
2. Push data into the setup.
3. After pushing the data, compare the actual size of data-pushed and the shown( by project, storageclass or pods)

Actual results: The usage values shown are lesser than the actual consumption.


Expected results: The usage values should be the same as consumption.

Comment 3 Oded 2020-03-19 09:17:30 UTC 
I tried to create PVC for Block Storage.
PVC on Pending Mode,rbd pool not found.
I tried to work with "ocs-storagecluster-cephblockpool",same results.

SetUp:
*AWS-IPI

*oc version:
(.venv) [odedviner@localhost ocs-ci]$ oc version
Client Version: 4.3.5
Server Version: 4.3.0-0.nightly-2020-03-18-011727
Kubernetes Version: v1.16.2


Test Process:
1.Activate ocs-env:
source .venv/bin/activate


2.Create pool Yaml file::
(.venv) [odedviner@localhost ocs-ci]$ cat pool.yaml
apiVersion: ceph.rook.io/v1
kind: CephBlockPool
metadata:
  name: rbd
  namespace: openshift-storage
spec:
  failureDomain: host
  replicated:
    size: 2


3.Create pool:
(.venv) [odedviner@localhost ocs-ci]$ oc create -f pool.yaml
cephblockpool.ceph.rook.io/rbd created


4. Get ceph block pool:
(.venv) [odedviner@localhost ocs-ci]$ oc get cephblockpool -n openshift-storage
NAME                               AGE
ocs-storagecluster-cephblockpool   103m
rbd                                27s


5.Create pvc.yaml file
(.venv) [odedviner@localhost ocs-ci]$ cat pvc.yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: ocs-pvc3
  namespace: openshift-storage
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 100Gi
  storageClassName: rbd


6.Create PVC
(.venv) [odedviner@localhost ocs-ci]$ oc apply -f pvc.yaml
persistentvolumeclaim/ocs-pvc3 created


7.Look at the PersistentVolumeClaim:
(.venv) [odedviner@localhost ocs-ci]$ oc get pvc -n openshift-storage | grep ocs-pvc3
ocs-pvc3                  Pending

                           
8.Check PVC status:
oc describe pvc ocs-pvc3 -n openshift-storage
(.venv) [odedviner@localhost ocs-ci]$ oc describe pvc ocs-pvc3 -n openshift-storage
Name:          ocs-pvc3

Comment 4 Afreen 2020-03-20 04:59:45 UTC 
@Oded

The Message says: storageclass.storage.k8s.io "rbd" not found
And when you create a storage cluster OCS creates rbd class with the name: {storage-cluster-name}-ceph-rbd.
I am not sure what environment you are setting by  (source .venv/bin/activate), but you should check the name of rbd storage class that you are putting in your PVC yaml.
