nfsstat question

[Jim Kriegel]

Hi,
I've been looking at the output of nfstat -rc and I noticed that I have timeouts and badxid's, but no retrans. Why wouldn't I have retrans if a call times out?

[Rick Garland]

A guess might be the protocol being used. UDP protocol vs TCP protocol. NFSv3 vs. NFSv2

[Jim Kriegel]

Our system is using ver 2 over udp. I makes sense that the retrans probably won't happen with udp. Would it safe to say that the timeouts are a result of a physical cable problem? I don't think the nfs server deamon is going up and down.

[Rick Garland]

The client RPC requests are timing out before the server can answer them.

Can increase the timeo parameter and/or reduce the NFS buffer size.

First step however would be to swap the cables. Could very well be a bad cable.
