Issue occurs only in CageFS

Introduction

This article aims to provide some troubleshooting steps when an issue occurs when a user has CageFS enabled.

Procedure

Typically the following commands can be used when a systemwide change has been made and users are not able to use them. Often, a system file is changed or fixed, but users still only see the old data because of how CageFS works.

When you see an issue with a user on a CloudLinux system with CageFS enabled, try running these commands as root in SSH:

Remount CageFS, then force an update:

cagefsctl -M
cagefsctl --force-update

If all else fails, reinitialize CageFS:

cagefsctl --reinit

To confirm that the issue only occurs in CageFS, disable CageFS for the user temporarily:

cagefsctl --disable user

To enable it again:

cagefsctl --enable user
