Does SCVMM 2012 R2 support Server 2016 SMB shares?

Hi

I'm trying to add a Windows Server 2016 Scale-Out File Server SMB share to the storage providers on SCVMM 2012 R2 but receive the error below:

Error (26311)
Registration of the storage subsystem svlab.domain.com for user DOMAIN\vmmadmin failed from SVSCVMM.domain.com with error code 46006 [SM_RC_SUBSYSTEM_ALREADY_REGISTERED].

Recommended Action
Specify a valid subsystem name, and user credentials for registering the subsystem.

Error (26200)
The volume information for C:\ClusterStorage\Volume1\SHARES\VMDISK01 cannot be acquired.

Recommended Action
Select a different share, and then try the operation again.

The cluster is using Storage Space Direct, and I can access it and create files on the share from the VMhosts and the SCVMM box as well. Just wondering if this is an unsupported config and do I have to go to SCVMM 2016....

thanks

Phil
