--- Comment #2 from Rik Theys <rik.theys at esat.kuleuven.be> ---
Hi,

I first experienced the bug when using NFS ganesha. The export from
ganesha.conf:

EXPORT {
        Export_Id = 1;
        Path = "/";

        FSAL {
                Name = GLUSTER;
                hostname = "ox-gluster.esat.kuleuven.be";
                volume = "vol_rep3_arb";
        }

        Access_Type = RW;
        Pseudo = "/vol_rep3_arb";
        SecType = "sys";

        CLIENT {
                Clients = @esat.nfs.dns;
        }
}

I then tried to reproduce the issue using a glusterfs mount on one of the brick
servers, but was unable to reproduce it.

Then I mounted it using the fuse client on one of the brick servers and
exported the mountpoint using kernel nfs. When mounting it like this, I was
able to reproduce it.

So I can reproduce the issue with both NFS implementations, but not when using
the fuse client.

Regards,

Rik
