Troubleshooting NFS
Most problems involving NFS
network services lie in one of the
following areas:
----------------------------------------------------------------- Command Function ----------------------------------------------------------------- rpcinfo(NADM) displays RPC information from a specified RPC server. Use rpcinfo to make sure theportmapper (/etc/portmap) is running and to ensure the Network Lock Manager is running. If exporting filesystems, the mountd service should be registered. showmount(NADM) displays the clients that have remotely mounted filesystems from a specified server. nfsstat(NADM) displays statistical information about NFS and about Remote Procedure Call (RPC) interfaces to the kernel; can also be used to reinitialize this information. netstat(TC) displays statistical information about TCP/IP; it is particularly helpful for identifying physical network problems. ping(ADMN) reports roundtrip time and packet loss statistics. Use ping to ensure a network connection can be made between hosts.
