If you are a block layout server, the only valid return value is EXCHGID4_FLAG_USE_PNFS_MDS 'cos you are clearly not a non-metadata server, and you clearly can't be a data server. Sorry to be dense, this is the first time I've thought about this. At the time of the EXCHANGE_ID call, how is the server supposed to know what kind of layout is going to be negotiated?
