Epic Goal

• Allow users to recover from volume expansion failure if they have resized to a larger/unsupported size.
• https://issues.redhat.com/browse/STOR-263

Why is this important?

• This is a requirement for moving volume expansion to GA and will allow end users to recover from volume expansion failures by themselves without requiring admin intervention.

Scenarios

1. An user expands 100GB PVC to 100TB by mistake and since underlying storage provider does not have that much space available, user have no way to correct that error.
2. User should be able to retry volume expansion to a lower value such as 500GB (down from 100TB)

Acceptance Criteria

• Users should be able to reduce size to a lower value and retry volume expansion.
