Thank you for the advice - it got me past that obstacle. After a bit of fighting with SELinux (nfs-ganesha wanted some fuse access privileges) I managed to have a filesystem exported. However, I am now having trouble with permissions on the client (no user, including root, is allowed to change to the mounted directory). I guess this has to do with id mapping. When the server starts, it prints this message init_server_pkgs :NFS STARTUP :EVENT :Initializing ID Mapper. init_server_pkgs :NFS STARTUP :EVENT :ID Mapper successfully initialized. so it appears it is using its own mapper because the system one is not running. But how do I configure it to work properly? The kernel NFS server requires no configuration of id mapping, but here I am at a loss.
