ProcedureHow to Check the NFS Server Remotely

Note that support for both the UDP and the MOUNT protocols is not necessary if you are using an NFS version 4 server.

  1. Check that the NFS services have started on the NFS server by typing the following command:


    % rpcinfo -s bee|egrep 'nfs|mountd'
 100003  3,2    tcp,udp,tcp6,upd6                nfs     superuser
 100005  3,2,1  ticots,ticotsord,tcp,tcp6,ticlts,udp,upd6  mountd  superuser

    If the daemons have not been started, see How to Restart NFS Services.

  2. Check that the server's nfsd processes are responding.

    On the client, type the following command to test the UDP NFS connections from the server. 


    % /usr/bin/rpcinfo -u bee nfs
program 100003 version 2 ready and waiting
program 100003 version 3 ready and waiting
    Note –

    NFS version 4 does not support UDP.

    If the server is running, it prints a list of program and version numbers. Using the -t option tests the TCP connection. If this command fails, proceed to How to Verify the NFS Service on the Server.

  3. Check that the server's mountd is responding, by typing the following command.


    % /usr/bin/rpcinfo -u bee mountd
program 100005 version 1 ready and waiting
program 100005 version 2 ready and waiting
program 100005 version 3 ready and waiting

    If the server is running, it prints a list of program and version numbers that are associated with the UDP protocol. Using the -t option tests the TCP connection. If either attempt fails, proceed to How to Verify the NFS Service on the Server.

  4. Check the local autofs service if it is being used:


    % cd /net/wasp

    Choose a /net or /home mount point that you know should work properly. If this command fails, then as root on the client, type the following to restart the autofs service:


    # svcadm restart system/filesystem/autofs

  5. Verify that file system is shared as expected on the server.


    % /usr/sbin/showmount -e bee
/usr/src										eng
/export/share/man						(everyone)

    Check the entry on the server and the local mount entry for errors. Also, check the namespace. In this instance, if the first client is not in the eng netgroup, that client cannot mount the /usr/src file system.

    Check all entries that include mounting information in all the local files. The list includes /etc/vfstab and all the /etc/auto_* files.
