I don't know how to manage layout segments in a way that meets the pNFS goals of scalability and performance, and neither you nor the pNFS spec have told me how to do this. If IBM wants a client that implements layout segments, then it is _your_ responsibility to: A. Convince me that it is an implementable part of the spec. B. Provide me with an implementation that deals all with the concerns that I have. IOW: nobody has ever promised IBM that the community would do all your client work for you. EMC, NetApp and Panasas have implemented (most of) the bits that they cared about; any bits that they haven't implemented and that you care about are up to you. -- Trond Myklebust Linux NFS client maintainer NetApp Trond.Myklebust@xxxxxxxxxx www.netapp.com -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
