$ du -ah /path/to/directory/ | sort -hr | head -20 The following command lists the 20 largest files and directories, sorted by size: If you got SSH access then you can get more accurate data. The disk usage stats are refreshed every few hours, so cPanel may still show that your account is over its quota after you have cleared some space. One thing to bear in mind is that the statistics shown are unlikely to be bang up to date. You can check how much disk space your account uses via cPanel’s Disk Usage interface. That is because your email stops working when you suddenly run out of disk space – you wouldn’t receive the warning email. It is a good idea to have at least one email address that is not hosted on the server. The email is sent to the email address(es) shown under Preferences » Contact Information. On cPanel servers you get a notification email when your account uses over 80% of its disk space quota. Here, has a quota of 1GB, and the mailbox is using 500MB. Image: the ‘Email Accounts’ overview in cPanel. When the mailbox is 500MB in size the hosting package has run out of disk space, even though the mailbox is only half-full. You got one mailbox, and the quota is set to 1GB. To illustrate the point, let’s imagine that your hosting package has 500MB of disk space. If you hit the quota for your hosting plan your email still stops working. Changing the quota to “unlimited” only means that the mailbox is never be considered full. That sounds ideal, but it doesn’t give you unlimited space for your email.
You can change the quota, and you can even set it to “unlimited”. Mailbox quotasĮach email address has a disk space quota. There is a good reason why databases are not affected by disk space quotas: your data gets corrupted if writes fail. In short, when you run out of disk space pretty much everything stops working. Image: cPanel is not allowing files larger than zero bytes to be uploaded.
Similarly, when you upload a file using cPanel’s file manager you get the error “Maximum file size allowed for upload: 0 bytes”. Image: FileZilla showing an error 451 (“Error during write to file”). For instance, in FileZilla you typically see “451-error during write to file” in the message log. When you upload files via FTP you may see an error 451. After a week the server gives up, and the emails are bounced back to the sender.Īs said, FTP is also affected. The emails are kept in the mail queue for up to a week, and during that time the server tries to deliver the emails at set intervals. When you run out of disk space incoming emails can’t be delivered to your inbox. When a quota has been reached you can no longer write data to the server’s file system, and you will therefore see an error. On top of that, individual email or FTP accounts may also have quotas. Every hosting plan has a finite amount of disk space.
