Folks, a bit of a puzzler... For a long time (years), have had sparc-solaris8 NFS clients (well-patched) talking to a RH/Fedora NFS server, recently FC4 (x86_64). The mount options, dished out through autofs, were (probably sub-optimally): -rw,nosuid,nodev,sync,retry=5,rsize=16384,wsize=16384,intr These were lightly-used clients; it worked; everybody happy. I yum-upgraded the server to FC5 (current kernel, nfs-utils). It works.. most of the time, but the clients now often-but-not-always wander off into... NFS server foo not responding still trying NFS server foo ok ... with a 20-, 30-, 60-minute gap between the two being common (but not predictably so). Nothing in the server logs; only that in the clients'. Thinking that maybe my old-crufty set of mount options needed fixing, I switched to a very simple set: -rw,nosuid,proto=tcp,vers=3,intr Didn't make the slightest difference. I have Linux clients, same mount options, same everything, which worked fine before -- and they still do. There have been no cabling or other changes -- just the switch from FC4 to FC5 on the server. Ideas? Thanks, Will
