Exporting Gluster volumes over FUSE and kernel NFS is not something we
suggest and test. There are (or at least were) certain limitations in
FUSE that prevented good support for this.

Please use NFS-Ganesha instead, that is the NFS server we actively
develop with. Gluster/NFS is still available too, but is only receiving
the occasional fixes and is only suggested for legacy users that did not
move to NFS-Ganesha yet.
