Just glancing at the code it seems that the Solaris NFSv4 client does support volatile FHs. > > > The Solaris NFSv4 server does not support volatile filehandles. > > > > Is there a bugid for this ? > > [Actually, I could have been wrong about that.] > > Not that I know of, but I wouldn't be one to know.

There is code in the Solaris NFSv4 server for volatile, most of it #ifdef'ed out (VOLATILE_FH_TEST). Adding a pathconf by which to discover whether a filesystem has volatile handles would make it possible to un-ifdef out the relevant code.
