      The GCP PD CSI driver does not support hyperdisk-balanced volumes with RWX mode. Attempting to provision hyperdisk-balanced volumes with RWX mode using the GCP PD CSI driver produces errors and does not mount the volumes with the desired access mode.

      This was fixed and customers are now able to provision hyperdisk-balanced volumes with RWX mode. However, there are many limitations with this mode see https://cloud.google.com/compute/docs/disks/sharing-disks-between-vms#mw-limitations.
