How to resolve the issue of NFS mounting not showing any response?

If there is no response when trying to mount NFS, it may be due to the following reasons:

1. Network connectivity issue: First, make sure that the network connection between the NFS server and client is working properly. You can try using the ping command to check the connectivity between the two.
2. Ensure that the NFS server is properly configured and running. Verify that the NFS server configuration file (/etc/exports) is correct and that the NFS service is started.
3. Client configuration issue: Ensure that the NFS mounting point is correctly configured on the client side. You can check the configuration in the /etc/fstab file and make sure that the directory for mounting point has been created.
4. NFS Version Issue: There are multiple versions of NFS, make sure both the server and client are using the same version. You can try specifying the NFS version in the mount command, such as using the command mount -t nfs4.
5. Firewall configuration issue: Ensure that the firewall is not blocking NFS communication. You can try temporarily disabling the firewall or adding the necessary rules to the firewall.

If the issue persists, you can try examining the system logs (such as /var/log/messages) for additional error information, or use NFS-related commands (such as showmount) for troubleshooting.
