You must use the syntax of exports(5) also with zfs set sharenfs=3D AFAIK, you shouldn=E2=80=99t use /etc/exports to do zfs exports but the = above command If your hosts you export to are in your nfs-server=E2=80=99s /etc/hosts, = you will need to use the names they resolve to also in the = exports-statement. (Though that might be wrong - it was the case with Solaris, though). uids/gids should match, too, of course. Rainer=
