RomM On Unraid: Scheduled Tasks & Scan Issues

Introduction: The Unsolved Mystery of RomM's Scanning Problems

Are you experiencing issues with scheduled tasks not starting or library scanning failing in RomM, particularly on your Unraid server? You're not alone. This document delves into a specific bug reported by a user experiencing difficulties with RomM version 4.4.0. The user's experience highlights a frustrating scenario: the scan button is clicked, the scan wheel spins, and the logs indicate a scanning process has begun, but the task remains stuck in a "Queued" state within the admin panel. Furthermore, attempts to abort the scan yield a "No running scan to stop" message, suggesting a disconnect between the reported activity and the actual execution of the scan. This article aims to break down the reported issue, offering insights into the problem, potential causes, and possible solutions based on the user's provided information and common troubleshooting techniques for Unraid and containerized applications. This investigation will cover the steps to reproduce the issue, analyze the expected behavior, and provide potential solutions to resolve the scheduled tasks and scanning issues in RomM on Unraid. In the following sections, we'll explore the user's specific setup, analyze the logs, and consider broader Unraid-related issues that might contribute to this behavior. We'll also examine the role of the RomM configuration and the interaction between the application and the Unraid environment. Understanding these aspects is crucial to effectively address the scanning problems.

The Problem Unveiled: Symptoms and User Reports

The user's report is quite detailed, allowing us to grasp the core of the problem. The primary symptom is the failure of library scans to complete. After initiating a scan, the user observes the scan wheel spinning, but the scan never progresses beyond a "Queued" status in the admin panel. Additionally, attempting to abort the scan doesn't work, indicating that the system doesn't recognize an active scan to stop. The provided logs give us key clues about what is happening on the server. Although the logs show the scanning process is starting, there are no further updates to indicate whether or not the process is continuing. The user's operating system, Unraid 7.2.0, along with the use of containerized RomM, suggest a specific environment where similar issues often arise. The fact that the user tried both the standard install and the internal valkey-server without success strengthens the view that the underlying problem is either with the RomM configuration or the Unraid container's environment. Further investigation is required to identify the root cause of the scanning failures. This information serves as the foundation for our troubleshooting efforts.

Reproducing the Bug: Step-by-Step Guide and Expected Behavior

To effectively tackle this problem, we must understand how to reproduce it. The user has thoughtfully provided a clear set of steps to reproduce the issue: installing RomM from the official Container App (CA) in Unraid, adding a config.yml file from the examples provided, and then initiating a scan through the web GUI. The expected behavior is that the library scan should start and complete successfully, updating the RomM database with the information about the library content. However, in this case, the scan remains queued indefinitely, failing to finish the task. This failure disrupts the normal functioning of RomM, preventing the user from accessing the complete set of media content that the application is designed to manage. Successfully reproducing the issue is critical for both confirming the problem and later verifying potential fixes. The user's documented steps are crucial for replicating the issue, allowing for a controlled environment in which to experiment with solutions. The detailed setup of this configuration provides a valuable framework for anyone trying to troubleshoot the problem, as it outlines all of the steps needed to replicate the issue accurately, including the version of RomM, the Unraid version, and the specifics of the installation from the CA.

Detailed Steps to Reproduce the Issue

1. Install RomM: From the official Container App (CA) in Unraid, install the RomM container. This process typically involves selecting the application from the CA, configuring any necessary settings (e.g., ports, storage paths), and deploying the container. This setup is crucial to ensure that the issue's origin can be replicated from scratch. This process should ideally follow the official documentation for RomM to ensure that all necessary dependencies are installed correctly and that the application is running in its intended environment.
2. Add a config.yml file: Following the examples provided, create and add a config.yml file. This file contains the configuration settings for RomM, including the locations of the media libraries to be scanned. Incorrect configuration settings are known to cause problems with the scanning process. The example configurations are available to help guide the user in setting up their system. Make sure the configuration settings correctly identify the locations of the media files; otherwise, the scanning will fail.
3. Open Web GUI: Access the RomM web GUI through your web browser. This interface allows you to interact with RomM, view the current status of your libraries, and initiate scans. This step helps the user interact with the application and see whether or not a scan can run.
4. Click "Start Scan": Within the web GUI, locate and click the "Start Scan" button, which initiates the library scanning process. The user will be able to start the scanning process through the web GUI.

Expected vs. Actual Behavior: The Disconnect

The expected behavior is straightforward: upon clicking "Start Scan", RomM should begin scanning the specified library folders and update its internal database with the information about the media files it finds. This is the core functionality that provides access to the user's media content. The user should expect the scan to progress to completion, taking a variable amount of time depending on the size of the library and the performance of the Unraid server. However, the actual behavior is markedly different. Instead of a successful scan, the scan gets stuck in the "Queued" state. This indicates that RomM is not processing the scan, and the scanning operation is failing to start or complete as intended. This discrepancy between the expected and actual behaviors is what highlights the bug and necessitates further investigation.

Deep Dive: Analyzing Logs and Contextual Information

The user's report is greatly enhanced by the inclusion of logs and contextual information. The logs provide a valuable insight into RomM's internal operations and can reveal any errors or issues that might be preventing the scans from running. The user's environment, particularly Unraid 7.2.0, also provides important context. Unraid has unique characteristics that affect how containers operate, which might be a factor in this issue. The goal is to uncover clues about what is going on. By reviewing logs and understanding the environment, a better picture can be developed of the root causes.

Decoding the Logs: What the Logs Tell Us

The provided logs offer several key pieces of information, though they do not explicitly point to a specific cause. The logs show that RomM is initializing correctly, including the database migrations and startup tasks. It also shows the application has started without any apparent errors. When a scan is initiated, the log records the event of initiating a scan, yet no subsequent entries indicate the progress or completion of the scan. The log output is clean and provides initial information about the application. The absence of error messages in the logs might suggest that the problem isn't a straightforward software bug. Instead, it may be an issue of task scheduling, resource limitations, or even some form of container-related issue. The logs provide a baseline of what is happening. A deeper dive might be necessary to uncover additional errors.

Environmental Factors: Unraid and Containerization

Unraid is a NAS operating system known for its flexibility and containerization support, which uses Docker containers to run applications. Containerized applications, like RomM, depend on the underlying Unraid system for resource management, networking, and storage access. There are specific aspects of Unraid that may cause issues for containers. The first thing that may need to be checked is the storage setup. If the storage path is not configured correctly, it will prevent RomM from being able to find the media folders to scan. Resource allocation is another key factor. Containers on Unraid are assigned resources such as CPU and memory. Insufficient resources can cause scanning issues, especially for large libraries. Networking is also critical. If the networking settings are not correctly configured, it may prevent RomM from accessing the internet. The network setup is what allows RomM to get metadata and other files that are required for scanning. Knowing these issues can help uncover issues.

Troubleshooting Strategies: Addressing the Issue Head-On

With a clear understanding of the problem and the context, it's time to devise troubleshooting strategies. The goal is to identify the root cause of the scanning failures and, if possible, implement a fix. This involves a systematic approach, starting with basic checks and progressing to more advanced diagnostics. The focus is to address the specific symptoms reported by the user and to consider the environment that the application is running in. We will consider the configuration, review the Unraid settings, and explore container-related issues.

Configuration Review: Double-Checking RomM's Settings

One of the first steps should be to review RomM's configuration file (config.yml). This file contains essential settings that control how RomM functions, including the location of the media libraries to be scanned. Any errors in this configuration file may cause scanning issues. Make sure the configuration file has the correct file paths for the media files. It's a common mistake that can easily cause scanning to fail. Confirm the file paths by double-checking them. If the file paths are correct, double-check the other configuration settings, such as network settings or database settings, to ensure that they are correctly configured and that they match the requirements of your Unraid environment. Check the other settings and make sure they match the Unraid environment configuration. This includes any network settings and database settings.

Unraid-Specific Checks: Resource Allocation and Permissions

Unraid has many settings that affect container performance. In Unraid, containers run inside of Docker, and there are several areas that must be checked. First, examine the resource allocation for the RomM container. In the Unraid Docker settings, ensure the container has enough CPU cores and memory. If the container is lacking resources, the scan process may hang or fail silently. The other thing to consider is permissions. Make sure the container has the necessary permissions to read the media files. This typically involves ensuring that the user ID and group ID within the container match the user and group owning the media files on the Unraid array. Check the settings inside of Unraid to ensure there are no issues. Check these settings and correct them if you find issues.

Advanced Diagnostics: Container Logs and Network Issues

If the basic checks don't solve the issue, advanced diagnostics are needed. Start by reviewing the container logs. These logs provide more detailed information than what is available in the web interface. To access the container logs, use the Unraid Docker settings or the command line. Network-related issues are another area to investigate. Ensure that the container can access the internet to download metadata or access external resources. Verify that the necessary ports are open. This can be checked by making sure that your firewall is configured properly. Use tools to check connectivity. If there are connectivity issues, the scanner will not be able to find the files needed. These diagnostic steps can help to identify more complex issues.

Potential Solutions and Workarounds: Putting Theory into Practice

After diagnosing the issues, it's time to test any proposed solutions. The next step is to test the proposed solution to see if it works. Since the provided information does not reveal the cause, several potential solutions should be explored.

Restarting the Container and Unraid

A simple but effective solution is to restart the RomM container and, if necessary, the entire Unraid server. This clears any temporary issues that may be causing the problem. Restarting can solve a lot of problems. Often, just restarting the program can resolve the issue. If restarting the container doesn't work, try restarting Unraid. This restarts the server and resets the system. This can resolve issues related to the underlying system.

Reinstalling RomM: A Fresh Start

If restarting does not work, the next step is to reinstall RomM. This is a more drastic measure, but it ensures a clean installation. Back up any important configuration files before reinstalling. Then, remove the container and install it again. After the installation is complete, test the scan functionality and see if the issue is resolved. The reinstallation can eliminate the configuration issues that may be present.

Addressing Permissions and Storage Paths

Ensure that the container has the correct permissions to access the media files. Check the storage paths in the config.yml file to make sure they are correct. Verify that the user ID and group ID within the container match the user and group owning the media files on the Unraid array. You can verify this by checking the container settings and the Unraid user settings.
