In powerful servers, we disable this cache (choose off), as server load isn’t affected.To fix this, our tech support team uses two approaches: cPanel stores disk usage info for 15-30 mins, to reduce disk access, and thereby keep down server load. It is caused by a cPanel feature called “disk quota cache”. That is, even if a 1 GB file is deleted, the space usage doesn’t show any difference. In cPanel servers, even after a disk quota exceeded error is resolved, the web panel shows the old disk space info. So, if you’re a shared web host, increase the quota by 100 MB temporarily so that services to the user is immediately restored. Business mails coming in during this period will bounce. Pro Tip : All this detective work takes time. We resolve this issue by searching the whole file system with the username, deleting them, and then updating the quota table. We’ve found such files in /usr, /var, / or in some cases even in /root directory. This could be from past troubleshooting steps, incomplete site restore, etc.
In self-managed VPS servers, we’ve found user files stored outside the user’s home directory. Special case – User’s files located outside home directory Once we’ve found the top directories, we drill down until we locate all non-essential files. That is why we use Linux command line tools (such as du) to list all directories in a user’s account, and sort them as per size. It’s not easy to find these space files if you look at a web panel report. Old uncompressed backups (from a previous site restore for eg.).But there are other locations that are not so obvious: In many cases, we’ve found large files (such as backup, videos, DB dumps, etc.) in the user’s home directory itself. Fixing mail/web space overageĪbout 80% of disk quota exceeded errors occur due to users uploading files beyond their subscription limit. Today, we’ll take a look at how to troubleshoot, fix and prevent quota exceeded errors. Users exceeding their mail or web space quota.Website owners see this error when they try to upload a file, send a mail or update a database.Įvery month, our engineers resolve hundreds of “Disk Quota Exceeded” errors in our role as website support for web hosting companies. Disk Quota Exceeded is a common error in Linux web hosting servers.
