In reality, you’ll be dealing with lots of smaller files, but you can use the same process of identification and deletion with cPanel and the command line to find and remove any quantity of unwanted data.Īs always, if you have any feedback or comments, please let us know. If we go back to WHM’s Disk Usage page, we see that the device is no longer full, and the problems caused by the lack of storage space have been resolved.ĭisk space problems are rarely caused by a single large file. The -r option means “recursive,” and it makes rm delete everything inside a directory. It tells rm to delete files without asking permission first. If you want to delete a directory of files, use this command instead: rm -rf /var/largedirectory We know that it’s safe to remove /var/largefile.log, so we can delete it with the rm command: rm -f /var/largefile.log Deleting a file is irreversible, so you should do some research to verify that it doesn’t contain data that matters to your or the server. Now we have to decide whether we can safely delete it or not. We’ve found the culprit! There is an enormous 39GB file in /var. It’s difficult to spot the largest files when there are lots of them, so we’ll use sort to print big files first and head to grab the top 10.

The * means everything inside the / directory.Īs you can see, the /var directory consumes 40 GB, dwarfing the amount of data in the other directories. In the last step, we found the overfull drive was mounted on “/”, so that’s where we start our search. As before, -h tells du to output sensible units.Īt the end of the command is a file argument. The -s option produces a summary of the data so we can more easily identify large files and directories. Now we have verified that a disk is nearly full, we have to find out which files are responsible. We’ve underlined the interesting entry: the disk named /dev/vda1, which is mounted on the root (/) of the filesystem, is 92 percent full. You can ignore the tmpfs devices they’re virtual disks stored in memory and may not be present on your server.

The -h flag tells df to use human-readable units instead of spitting out confusing byte counts. It provides more or less the same information as Disk Usage, but it’s helpful if you want to start your investigation on the command line instead of in WHM. Check Disk Commandįirst, we’ll use the df tool to check disk space on the server’s hard drives. To find out which files are causing the problem, we log in with SSH and use the command line to investigate. In the above image, we see that one of the hard drives on this server is dangerously full.

The number of devices and their names differ depending on the configuration of the server, but if they are more than 90% full, you should delete old data.

You will find it under System Health in the WHM sidebar menu.ĭisk Usage shows a list of storage devices, their sizes, and how full they are. It checks Linux disk space and displays the results in an intuitive interface. When you’re concerned about disk space, WHM’s Disk Usage tool should be your first destination.

You will need to log in to your server using SSH to run file management commands.

While any user can manage their own files, only the root user can monitor and delete files owned by other users.

You need to be able to log in as the root user to manage files outside of your home directory.

There are a couple of prerequisites you should know about before we explain how to manage hard drive space. How to Manage your Hard Drive Space in cPanel In this article, we show you how to do just that with cPanel and the disk management tools on your Linux® server. We recommend that you keep at least 10 percent of the server’s storage free, which means you will occasionally have to check disk space and find unused data to delete.

When there’s no space to store new stuff, the performance takes a hit and some software will stop working altogether. Servers need to be able to write data to their hard drives. Without a regular clear out, data accumulates until it fills the server’s storage devices. In the case of servers, it’s not trash but data you have to kick to the curb every once in a while. Servers are your virtual home and, just like your real home, they can become cluttered with unwanted junk.
