Meta Description: Learn how to completely remove the Commvault agent from your Linux system manually. This comprehensive guide provides step-by-step instructions and troubleshooting tips for a clean uninstall.

Introduction

This guide provides a comprehensive walkthrough for manually uninstalling the Commvault agent from your Linux system. While Commvault provides its own uninstallers, manually removing the agent ensures a complete cleanup, resolving potential conflicts or issues. This process involves removing files, directories, and potentially entries from system configuration files. Always back up your system before proceeding. The exact steps might vary slightly depending on your Linux distribution and the Commvault agent version.

Pre-Uninstall Preparations

Before beginning the uninstall process, perform these crucial steps:

• Backup: Create a full system backup. This precaution is essential to safeguard your data in case anything goes wrong during the uninstall.
• Identify Agent Version: Determine your Commvault agent version. This information is usually found in the agent installation directory or within the agent's configuration files. Knowing the version helps you identify specific files and directories related to the agent.
• Stop Commvault Services: Halt all Commvault agent services running on the system. Use the appropriate command for your system's init system (systemd, init.d, etc.). This usually involves commands like systemctl stop commvault-agent or service commvault-agent stop. Verify the services are stopped before proceeding.
• Check for Running Processes: Use the ps aux | grep commvault command to verify that no Commvault processes are running.

Step-by-Step Uninstall Process

The following steps outline the manual uninstall procedure. Remember to adapt these commands based on your actual installation path. The default installation path is often /opt/commvault/, but it might differ.

1. Removing the Agent Directory:

Begin by deleting the main Commvault agent directory. This is typically located at /opt/commvault/. Use the following command:

sudo rm -rf /opt/commvault/

2. Removing Configuration Files:

The agent might leave behind configuration files in various locations. Check these common locations and remove any relevant Commvault files:

• /etc/commvault/: This directory often contains agent configuration files. Remove all files and the directory itself: sudo rm -rf /etc/commvault/
• /etc/init.d/ (or /lib/systemd/system/ for systemd): Remove any Commvault service scripts or unit files. For systemd, this might involve commands like sudo rm /lib/systemd/system/commvault-agent.service followed by sudo systemctl daemon-reload. For other init systems, find and remove the relevant script.
• User's home directory: Look for hidden configuration files related to Commvault in the user's home directory (e.g., .commvault).

3. Removing Leftover Packages (If Applicable):

If the Commvault agent was installed using a package manager (like RPM or DEB), you'll need to remove the package using the appropriate commands:

• RPM-based systems (e.g., Red Hat, CentOS): sudo rpm -e --nodeps <package_name> (replace <package_name> with the actual package name)
• DEB-based systems (e.g., Debian, Ubuntu): sudo apt-get purge <package_name> (replace <package_name> with the actual package name)

4. Verify the Uninstall:

After completing the above steps, verify that the agent has been completely removed. Check for any remaining files or directories related to Commvault. Re-run ps aux | grep commvault to confirm that no Commvault processes are running.

Troubleshooting

If you encounter problems during the uninstall, consider the following:

• Permissions: Ensure you have the necessary root privileges (using sudo) to delete files and directories.
• Locked Files: If files are in use, you might need to stop relevant services or processes before deleting them.
• Partial Uninstall: If the uninstall is incomplete, carefully review each step to identify any missed files or directories.
• Log Files: Examine Commvault log files for any error messages that might provide clues about the issue.

Conclusion

Manually uninstalling the Commvault agent on Linux requires careful attention to detail. Following these steps will ensure a complete removal of the agent, leaving your system clean and ready for other software installations. Remember to always back up your data before performing any significant system changes. If you're unsure about any step, consult the Commvault documentation or seek assistance from their support team.
