Why Deleting .cagefs is a Critical Mistake in Web Hosting?

Web hosting providers constantly strive to offer their clients the safest and most stable user experience. One of the tools used to achieve this is CloudLinux's CageFS, a system that isolates each user account to protect it from potential external threats. An essential component of this system is the .cagefs directory. Therefore, deleting this directory can have dire consequences.

What is .cagefs?

The .cagefs directory is an integral part of the CageFS system, acting as a virtual "cage" for each user account. It isolates users so that they cannot see or access other users' files and cannot view system information.

What happens if you delete .cagefs?

  1. Compromised Isolation: Without the .cagefs directory, CageFS will not operate correctly. This means that the isolation between accounts would be compromised, potentially exposing user data to risks.

  2. Operational Issues: Applications and services that rely on the presence of .cagefs might not function correctly, leading to errors and website downtimes.

  3. Security Concerns: Deleting .cagefs can expose the system to vulnerabilities as one of its primary functions is to isolate users and prevent potential security breaches.

What should you do if you've deleted .cagefs?

If you're a client and mistakenly deleted the .cagefs directory, the first step is to immediately contact your web hosting provider's technical support team. They'll be able to restore the directory and ensure the system operates properly.


The .cagefs directory is vital for the security and stability of web hosting accounts running on CloudLinux. It's crucial to ensure it remains intact and to avoid modifying or deleting it. If you have concerns or queries, your hosting provider's technical support team is there to assist you.
