Every Linux system administrator allocates certain disk space for the system files, which is known as disk quota. When the limited disk quota has been used up, and the web hosting servers try to store a new file, you get the error message “Disk Quota Exceeded.” The users encounter a common error when the disk quota exceeds the group disk or home directory. Sometimes, temporary files of the system are stored on the home directory, so make sure not to use the home directory for temporary webserver files. Read more on how to fix getting a disk quota error.
