Troubleshooting and tuning NFS

Clearing startup problems

A potential problem can occur if the name of the machine is changed with the uname command.

When the system hostname is changed with the uname command, the hostname entries in the /etc/net/*/hosts and /etc/inet/hosts files are not updated. This causes the rpcbind daemon to fail.

To clear startup problems, do the following:

  1. Check if the NFS daemons and the rpcbind daemon are running, using nfsping -a.

  2. Check if the system hostname matches the entry in the /etc/net/*/hosts files. For example, if the machine's hostname was hulk (as returned by uname -n), the entry in each of the /etc/net/*/hosts files should look like:
    hulk	hulk
    

  3. Check the /etc/inet/hosts if it has an entry for hulk.

  4. If the first entry in each of the /etc/net/*/hosts files does not match the machine's hostname, then do the following in order:
