> This will allow the framework to "import" pre-existing volumes reported by
> the corresponding CSI plugin.
> For instance, the LVM CSI plugin might detect some pre-existing volumes that
> Dan has created out of band. Currently, those volumes will be represented as
> RAW "disk" resource with a volume ID, but no volume profile by the SLRP. When
> a framework tries to use the RAW volume as either MOUNT or BLOCK volume,
> it'll issue a CREATE_DISK operation. The corresponding SLRP will handles the
> operation, and validate against a default profile for MOUNT volumes. However,
> this prevents the volume to have a different profile that the framework might
> want.
> Ideally, we should allow the framework to optionally specify a profile that
> it wants the volume to have during CREATE_DISK because it might have some
> expectations on the volume. The SLRP will validate with the corresponding CSI
> plugin using the ValidateVolumeCapabilities RPC call to see if the profile is
> applicable to the volume.
