  1. Hi happyvinod,

    Try to set SELinux to permissive mode and see if it works.

    $ sudo setenforce 0


    If it does work after setting SELinux to permissive mode, then the problem is SELinux. You will have to add the required SELinux permissions to the nfs directory for it to work. If you don’t want to configure SELinux and it’s not a production server, then you may keep it simple and disable SELinux.


    If it does not work after setting SELinux to permissive mode, then there might be some other problem.


    Let me know what happens once you set SELinux to permissive mode.


    Good luck.
