The problem is your server is sending back a "Connection refused" error instead of an error that would cause autonegotiation. The mount command in interprets "Connection refused" errors as the server is down and will continue to retry in the likely hood the server is on its way back up... If you notice in your other examples errors like "RPC: Program not registered" and "Operation not supported" were returned not "Connection refused". Those types of error cause the autonegotiation to occur. If the server did return "Connection refused" in those examples the same retries would occur... So your server obviously does not support v4 and does not know how to (correctly) error out when v4 bits are thrown at it... My suggestion would be added the following lines to /etc/nfsmount.conf [ Server "server" ] Defaultvers=3 which means start the autonegotiation at v3 with that particular "server" |
