How to remove Swap Space from Centos 7.x?

Please refer to the following steps to remove Swap space from Centos 7.x

  1. At first, check if your system is running with the swap space or not with the below command. It will list the swap space with its location.

    swapon -s


  2. As per the above location, swap space is located at /dev/vdb location since it is a virtual server. Now, we will disable the swap space by executing the below command.

    swapoff -v /dev/vdb
  3. After that, you can check with the free command to verify that swap is disabled.

    free -m 


  4. Remove swap entry from /etc/fstab. To do this edit the file fstab and remove the swap entry.



  5. Let’s regenerate mount units to registers the new configuration:

    systemctl daemon-reload
  6. Finally, remove the actual swap file.

    rm -rf /dev/vdb

    This is it. We have successfully removed the swap space.
