Description Ben Eli 2020-03-18 16:16:16 UTC 
Description of problem (please be detailed as possible and provide log
snippests):
When creating a new PVC BackingStore via the management console 
(Operators -> Installed Operators -> OCS -> Backing Store -> Create -> Provider=PVC)
The Volume Size can be set to lower than 16GB, which is the bare minimum needed for the feature to work.

The creation works in the end, but uses 20~GBs (which is defined as the minimum in the CRD. Changed to 16 as part of 1813655) even if the user chose 1GB.

Version of all relevant components (if applicable):
OCS 4.3.0-376.ci 
OCP 4.3.0-0.nightly-2020-03-16-193416

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

Rate from 1 - 5 the complexity of the scenario you performed that caused this
bug (1 - very simple, 5 - very complex)?
1

Can this issue reproducible?
Yes

Can this issue reproduce from the UI?
Yes

Actual results:
Creation is possible with any size the user wishes

Expected results:
Creation should be blocked in case the size given is lower than 16GB
Comment 1 Bipul Adhikari 2020-05-21 06:18:58 UTC 
The frontend should not be handling the validation of the minimum size. backend should reject it if the minimum size limit is not fulfilled in the request sent by the console UI. Moving back to MCG>
Comment 5 Ben Eli 2020-07-19 14:42:59 UTC 
Creation is allowed, backingstore enters a rejected state with the message "NooBaa BackingStore "pvcback" is in rejected phase due to insufficient size, min is 16000000000=16GB"

Verified.
