Description of problem (please be detailed as possible and provide log
snippests):

[vSphere]: On a fresh Arbiter deployment (3M + 6W), PG state is not active+clean which result in blocking of creating default OSD PDB

ocs-registry:4.16.0-135

Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?
No

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

3/3

Can this issue reproduce from the UI?
Not tried

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

Steps to Reproduce:
1. install Arbiter deployment 
2. check all PDB's are created
3.


Actual results:

$ oc get pdb

Expected results:

Default OSD pdb should be "rook-ceph-osd"


Additional info:

Some times we see 2 PDBs created for OSD.
