Re: NFS gateway

    I really think that doing async on big production environments is a
    no go. But it could very well explain the issues. 

    Last week I used to test Ganesha and so far the results look
    promising.

      I have clients accessing CephFS over nfs (kernel

        a chance to investigate and in the meantime I'm exporting with
        async (not recommended, but acceptable in my environment). 

        I've been meaning to test out Ganesha for a while now

        @Sean, have you used Ganesha with Ceph? How does
          performance compare with kernel nfs?

          Hi,

            One of the use-cases I'm currently testing is the
            possibility to replace

            a NFS storage cluster using a Ceph cluster.

            The idea I have is to use a server as an intermediate
            gateway. On the

            client side it will expose a NFS share and on the Ceph side
            it will

            mount the CephFS using mount.ceph. The whole network that
            holds the Ceph

            environment is 10G connected and when I use the same server
            as S3

            gateway I can store files rather quickly. When I use the
            same server as

            a NFS gateway putting data on the Ceph cluster is really
            very slow.

            The reason we want to do this is that we want to create a
            dedicated Ceph

            storage network and have all clients that need some data
            access either

            use S3 or NFS to access the data. I want to do this this way
            because I

            don't want to give the clients in some specific networks
            full access to

            the Ceph filesystem.

            Has anyone tried this before? Is this the way to go, or are
            there better

            ways to fix this?
