To mount a NFSv3 UDP only export you have to add a mount options (-o udp or -o nfsvers=3). This should be not necessary because of auto-negotiation. Reproducible: Always Steps to Reproduce: 1.Server with NFSv3 UDP only 2.Mount the server NFSv3 export without any options (-o udp or -o nfsvers=3) Actual Results: Mount fails with mount.nfs: mount(2): Connection refused Auto-negotiation is stuck on NFSv4. Expected Results: Mount success. In the attachment is my testcase log for following scenario: Client: openSUSE 13.1 32bit, Kernel 3.11.10-7-default Server_1: NFSv3 UDP only Mounting Server_1: NFSv3 UDP only without mount options (-o udp or -o nfsvers=3) == Fail Mounting Server_1: NFSv3 UDP only with mount options (-o upd or -o nfsvers=3) == Success Server_2: NFSv3 TCP/UDP Mounting Server_2: NFSv3 TCP/UDP without mount options (.o upd or -o nfsvers=3) == Success mount -v logs and /var/log/messages -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
