You probably know how important disk space is for all your computer-related activities, such as when you run, operate, manage, or own a website controlled by cPanel. Without enough disk space, you will ultimately run into problems, so make sure you maintain, at the very least, 10 per cent (or more) of your server’s disk space unoccupied and unused.
First off: Examine your usage
The first thing you need to do to maintain an optimal hard drive space is to examine your disk space usage.
With the command “df –h” (without the quotation marks), you can figure out the available space on the file systems of your server.
Successful execution of this command will provide you with a table displaying the basics of each of the mounted file systems, including how much disk space each file consumes.
Some of the basic information you will see in the table include the main root-mounted storage device of your system, your directories, how much space the directories use, and how much free space you still have.
Determining the biggest space-consumers
Another important part of hard drive space management includes the examination of disk space usage of each file and directory.
When you run the “du -sh /” command (without the quotation marks), you can spot the files and directories eating up the greatest amount of your hard drive space. It will give you data containing the estimated disk space each file and directory uses and summarize existing functional directory contents.
As a friendly reminder to avoid overloading your server and experiencing lag or down time, execute this command only during off-peak hours.
After running the du -sh / command, you will receive an output with two columns. On the left, you will see numbers representing file and directory sizes. In most cases, you will notice that the /home directory eats up the greatest amount of disk space. However, keep in mind that this directory most likely stores all the data of your cPanel accounts, the contents of which include the data of your users.
Avoiding accidents when freeing up space
Since you do not want to accidentally delete your cPanel users’ data, you should thoroughly examine the /var directory. Running the “du -sh /var/*” (again, without the quotation marks) will enable you to check disk usage data. The output you will get will tell you which directory consumes the highest amount of disk space. In most cases, this will show the /var/logs/ directory as the biggest space-consumer.
Eliminating unneeded and unnecessary files
One of the fastest ways to eliminate unneeded and unnecessary files is to execute the rm utility. This will free up some of your disk space, as it will remove some of the files contained in your file system. Practice extreme caution though when using this method, as it does not provide you with the option to recover directories and files it already deleted.
Hard drive space management is extremely important for all computer users, but even more so for those who have websites to run, operate, and manage. You want your website to remain functional at all times, so free up disk space to prevent any unwarranted problems.
