Hi list, this is probably an Ubuntu bug, however it put two different servers in the dumps, running different kernels so I send this in case it may help someone. Here is the sort of messages clogging the NFS servers logs: statd: server rpc.statd not responding, timed out lockd: cannot monitor ipntheo12 statd: server rpc.statd not responding, timed out lockd: cannot unmonitor ipnnester13 statd: server rpc.statd not responding, timed out lockd: cannot monitor ipngrid01.in2p3.fr statd: server rpc.statd not responding, timed out lockd: cannot monitor ipngrid01.in2p3.fr statd: server rpc.statd not responding, timed out lockd: cannot monitor ipngrid01.in2p3.fr statd: server rpc.statd not responding, timed out lockd: cannot monitor ipnweb2 statd: server rpc.statd not responding, timed out lockd: cannot monitor ipnweb2 statd: server rpc.statd not responding, timed out lockd: cannot monitor ipnweb2 lockd: server ipnweb2 not responding, timed out lockd: server ipnweb2 not responding, timed out There are about 80 NFS clients (home directories) on these. They worked perfectly for years until 2 clients were upgraded to 13.04. -- ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | <eflorac@xxxxxxxxxxxxxx> | +33 1 78 94 84 02 ------------------------------------------------------------------------ -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
