Please refer to the following steps to remove Swap Space from CentOS 7.x –
1. First, use the command below to check whether your system is running with the Swap Space.
swapon -s
It will list the Swap Space with its location
2. As per the above location, Swap Space is located at /dev/vdb since it is a virtual server.
We will disable the Swap Space by executing this command –
swapoff -v /dev/vdb
3. After that, you can check with the free command to verify that the Swap is disabled.
free -m
4. Remove the Swap entry from /etc/fstab.
To do this, edit the fstab file and remove the Swap entry.
5. Let’s regenerate Mount units to register 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.
