How to Troubleshoot NFS Client Connectivity Issues
Troubleshooting issues with a client connecting to an NFS server can involve
several steps, depending on the root cause. The following procedure describes
the logical sequence that you might follow to resolve NFS client connectivity
issues. If you do not resolve the problem by performing a given step, proceed to
the next step until you have identified and corrected the issue.
Check that the NFS server is reachable from the client system.
# ping nfs-server
If the NFS server is not reachable from the client, check that the local
naming service is running.
If the local naming service is running, check that the client has the
correct host information.
# getent hosts nfs-server
If the host information on the client is correct, try to reach the NFS
server by running the ping command from another
If the NFS server is reachable from the second client, check whether the
first client can connect to any other systems on the local network by using
the ping command:
# ping other-client-system
If other clients are unreachable, follow the steps that are described in
Running Basic Network Diagnostic Checks.
