What should I do if my NFS is not responding?
If not, examine the network interface card (NIC) settings using either ifconfig or ethtool to verify the IP settings. The NFS file system also reports “server not responding” when a heavy server or network loads cause the RPC message responses to time out. Use the “ timeo=N ” mount option on the client to increase the timeout.
What causes NFS server to fail to Mount?
# mount NFS-Server:/data /data_remote mount: mount to NFS server ‘NFS-Server’ failed: System Error: No route to host. This can be caused by the RPC messages being filtered by either the host firewall, the client firewall, or a network switch. Verify if a firewall is active and if NFS traffic is allowed.
How does the Network File System ( NFS ) communicate?
The Network File System (NFS) client and server communicate using Remote Procedure Call (RPC) messages over the network. Both the host->client and client->host communication paths must be functional. Use common tools such as ping, traceroute or tracepath to verify that the client and server machines can reach each other.
What does it mean when NFS says Access Denied?
Error: “Access Denied” or “Permission Denied” Check the export permissions for the NFS file system. You can do this from the client: If you see unexpected export permissions, check the /etc/exports file on the server. Make sure there is no syntax error such as space between the permitted host and the permissions.
Why is my NFS server saying no route to host?
The “no route to host” error can be reported when the client attempts to mount an NFS file system, even if the client can successfully ping the server: # mount NFS-Server:/data /data_remote mount: mount to NFS server ‘NFS-Server’ failed: System Error: No route to host.
Do you need root access to NFS server?
The NFS server should be configured so that it is exporting mount points that are accessible to the hosts via a trusted network. ESXi hosts must have root access to the NFS share. On non-windows NFS servers this is typically done using the no_root_squash option in the /etc/exports file.
