I can paste rpcinfo without options if you > need it though (there's a lot of output) There needs to nfs entries shown by rpcinfo on the server. Check with "ps ax" to see that the nfsd is running and then restart it. Until nfs entries show up for rpcinfo on the server, you'll be getting that "not registered" message when the mount is attempted. rick > > # rpcinfo -s > program version(s) netid(s) service owner > 100000 2,3,4 local,udp6,tcp6,udp,tcp,netlink rpcbind superuser > 100005 3,1 tcp,udp,tcp6,udp6 mountd superuser > > >Also, look in /var/log/messages for messages related to mountd. > >(I'd try a "service mountd reload" and then look for messages.) > > If I don't copy /etc/zfs/exports to /etc/exports, then showmount -e 192.168.1.230 > from the client doesn't work.
