      Description of problem:

      It is possible to request RWX filesystem volumes using the kubevirt csi driver and the driver will happily create a PV with a filesystem on it that is not compatible with RWX. This causes the volume to get corrupted because of concurrent writes to the meta dataa.

      Version-Release number of selected component (if applicable):

       

      How reproducible:

      100%

      Steps to Reproduce:

      1. Create HCP cluster using OCP-V as the provider. This installs kubevirt-csi driver
      2. In the tenant cluster create a PVC with RWX filesystem volumes.
      3. PVC is bound.
      

      Actual results:

      After creating the RWX filesystem PVC, the PVC gets bound to a PV

      Expected results:

      After creating the RWX filesystem PVC, the PVC remains pending and the appropriate error message is generated for the events. Something along the line of RWX filesystem is not supported.
