Description of problem (please be detailed as possible and provide log
snippets):
Observed during ocs-ci test "tests/manage/monitoring/prometheus/test_capacity.py::test_rbd_capacity_workload_alerts", which fills up storage till near-full and then clean it up. But after clean up of the PVCs, storage reclaim did not happen and the cluster is still staying with CephClusterNearFull warning.


Version of all relevant components (if applicable):
odf 4.9.0-164.ci

Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?
After this stage, the only solution is to scale up the cluster. 


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

Can this issue reproducible?
Intermittently reproducable

Can this issue reproduce from the UI?
no

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


Steps to Reproduce:
1. Install OCP, OCS
2. Install OCS-CI
3. Execute the ocs-ci test. I think this may be reproducable if we simply fill up a PVC that consumes more that 75% of ceph cluster capacity
