Systemd slice units are a way to organize and manage system processes in a hierarchical manner. If you receive this alert, it means that there is an issue with a specific slice unit, which can be crucial for system stability and performance. + +### What does the failed state mean? + +A `failed state` in the context of systemd units means that the unit has encountered a problem and is not functioning properly. This could be caused by a variety of reasons, such as misconfiguration, dependency issues, or unhandled errors in the underlying service. + +### Troubleshoot the alert + +- Identify the problematic systemd slice unit. + + Run the following command to list all systemd units and their states: + + ```bash + systemctl --all + ``` + + Look for the units with the `failed` state in the output, and take note of the affected unit(s). + +- Investigate the specific issue with the failed unit. + + Use the `systemctl status` command followed by the unit name to get more information about the problem: + + ```bash + systemctl status <unit-name> + ``` + + The output will provide more details on the issue and may include error messages or log entries that can help identify the root cause. + +- Check the unit logs for additional clues. + + The `journalctl` command can be used to view the logs related to a specific unit by specifying the `-u` flag followed by the unit name: + + ```bash + journalctl -u <unit-name> + ``` + + Analyze the log entries for any reported errors or warnings that could be related to the failure. + +- Address the root cause of the issue. + + Based on the information gathered, take the necessary steps to resolve the issue with the failed unit. This may involve reconfiguring the unit, adjusting dependencies, or fixing the underlying service. + +- Restart the unit and verify its status. + + Once the issue has been resolved, restart the systemd unit using the `systemctl restart` command: + + ```bash + systemctl restart <unit-name> + ``` + + Afterwards, check the unit's status to confirm that it is no longer in a failed state and is functioning properly: + + ```bash + systemctl status <unit-name> + ``` + |
