How to Verify the NFS Service on the Server

Become superuser or assume an equivalent role.

Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services. To configure a role with the Primary Administrator profile, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.

Check that the server can reach the clients.
# ping lilac lilac is alive

If the client is not reachable from the server, ensure that the local name service is running. For NIS+ clients, type the following:

% /usr/lib/nis/nisping -u
Last updates for directory eng.acme.com. :
Master server is eng-master.acme.com.
        Last update occurred at Mon Jun  5 11:16:10 1995

Replica server is eng1-replica-58.acme.com.
        Last Update seen was Mon Jun  5 11:16:10 1995

If the name service is running, check the networking software configuration on the server, for example, /etc/netmasks and /etc/nsswitch.conf.

Type the following command to check whether the rpcbind daemon is running.
# /usr/bin/rpcinfo -u localhost rpcbind program 100000 version 1 ready and waiting program 100000 version 2 ready and waiting program 100000 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. If rpcbind seems to be hung, either reboot the server or follow the steps in How to Warm-Start rpcbind.

Type the following command to check whether the nfsd daemon is running.

# rpcinfo -u localhost nfs
program 100003 version 2 ready and waiting
program 100003 version 3 ready and waiting
# ps -ef | grep nfsd
root    232      1  0  Apr 07     ?     0:01 /usr/lib/nfs/nfsd -a 16
root   3127   2462  1  09:32:57  pts/3  0:00 grep nfsd

Note –

NFS version 4 does not support UDP.

If the server is running, it prints a list of program and version numbers that are associated with the UDP protocol. Also use the -t option with rpcinfo to check the TCP connection. If these commands fail, restart the NFS service. See How to Restart NFS Services.

Type the following command to check whether the mountd daemon is running.

# /usr/bin/rpcinfo -u localhost mountd
program 100005 version 1 ready and waiting
program 100005 version 2 ready and waiting
program 100005 version 3 ready and waiting
# ps -ef | grep mountd
root    145      1 0 Apr 07  ?     21:57 /usr/lib/autofs/automountd
root    234      1 0 Apr 07  ?     0:04  /usr/lib/nfs/mountd
root   3084 2462 1 09:30:20 pts/3  0:00  grep mountd
