Comment 6 akarsha 2020-08-04 08:05:37 UTC

Tested on AWS IPI environment(internal mode)
- 3 master
- 3 worker(ocs)

Version
OCP: 4.5.0-0.nightly-2020-08-03-123303
OCS: ocs-operator.v4.5.0-508.ci

Verfication steps:

1. Install OCS and wait for cluster to be in Ready state.
2. Checked filesystem chart on Overview dashboard. The used metric is (sum(node_filesystem_size_bytes) - sum(node_filesystem_free_bytes)). It is not ceph_cluster_total_used_bytes.
3. Run some IOs and checked filesystem chart on Overview dashboard.

Snapshots:
- Filesystem chart just deployed OCS

- Filesystem chart after some IOs
