I have to write a script that would allow non root user to display LVM info. I have allowed that user in sudoer file but still not able to run that command returning with following error.

  WARNING: Running as a non-root user. Functionality may be unavailable. /run/lock/lvm/P_global:aux: open failed: Permission denied   Unable to obtain global lock.

If I run this command from using sudo 

Sorry, user farooq is not allowed to execute '/sbin/pvdisplay' as root on localhost.

Can anyone help me.

In order to allow a user run a certain script as root you have to edit /etc/sudoers or /etc/sudoers.d/<alt_sudoers_file>.

You are encouraged to do it using the command visudo. If editing alternative sudoers file user visudo -f <alt_sudoers_file>.

An example that can work for you would be:

%sudo   ALL=(ALL:ALL) ALL

This actually says the following: Any user of group sudo, on ANY host can run ANY command as root if the command is prefixed with sudo.

For full documentation run man sudoers

    At first glance, this looks like gibberish.  Upon closer look, I see that it appears to be a Unix command, but with no indication of what it means or how it relates to the question.  Please explain it, or it is likely to be deleted. … … … … … … … … … … … … … … … … … … … … … Please do not respond in comments; edit your answer to make it clearer and more complete.
