For the record, PROXY_V3 is not available in any released Ganesha yet, 
it will be in the upcoming V4.0 (which is in RC right now, and will be 
out before the end of the year).

 Hi there! You'll need to use a newer copy of Ganesha that has
PROXY_V3 
 built in. The old proxy is only an NFSv4 proxy. You're almost there, but 
 you need to use PROXY_V3 with a modern-ish Ganesha (and 
 use_privileged_client_port isn't an option, because NFSv3 doesn't 
 usually allow that). I just rewrote the instructions at:

 if you have any feedback!

     I'm currently using the centos 7 distribution and the
     centos-nfs-ganesha30 repo:
     # rpm -q -a | grep nfs-ganesha
     nfs-ganesha-vfs-3.5-2.el7.x86_64
     nfs-ganesha-3.5-2.el7.x86_64
     nfs-ganesha-proxy-3.5-2.el7.x86_64
     centos-release-nfs-ganesha30-1.0-2.el7.centos.noarch
 
     I've come across a strange need to get a nfsv3 share on a netapp
     talking with a client that only understands nfsv4. I think I'm
     heading in the right direction here but I'm having some trouble
     getting this setup for testing.
 
     In the log I am getting:
     init_export_root :EXPORT :CRIT :Lookup failed on path, ExportId=20
     Path=/prod FSAL_ERROR=(Permission denied,13)
     and it appears to give up on the /prod share
 
     my export config is:
     EXPORT {
        Export_Id = 20;
        Path = "/prod";
        Pseudo = "/prod";
        Access_Type = RW;
        Squash = No_Root_Squash;
        Transports = "TCP";
        FSAL {
          Name = proxy;
          Srv_Addr = <netapp ip>;
          Use_Privileged_Client_Port = false;
        }
     }
 
     I am able to mount the netapp share from this same system and manage
     the content of the share:
     mount -v -t nfs -o proto=tcp,vers=3,nolock <netapp ip>:/prod /prod
 
     not certain what I'm doing wrong, can anyone clue me in?
