A common issue arises when working with the fetch module, particularly when attempting to get filesystem details into a CSV file. Below, we will explore this issue and provide a step-by-step solution to ensure your filesystem details are correctly transferred. The Problem Let's set the stage: you are trying to gather filesystem details such as NAME, MOUNTPOINT, FSTYPE, and SIZE from your node servers and save them into a CSV file. However, after running your Ansible playbook, you notice that the CSV file is not being copied to the control machine, leading to confusion and frustration. You may have executed a playbook that looks like this: [[See Video to Reveal this Text or Code Snippet]] When running this playbook, even though it completes without errors, the CSV file fails to appear in the desired location on the control machine. The root cause of this problem lies in the fact that the fetch task has no reference to the created CSV file, as the shell command only writes it without returning any output for Ansible to work with. The Solution To resolve this issue, you need to adjust your shell command in a way that not only creates the CSV file but also echoes the file name for the fetch task to use. Here’s how you can do it: Step-by-Step Implementation Modify the Shell Command: Update the shell task to echo the generated file name after creating the CSV. The modified task would look like this: [[See Video to Reveal this Text or Code Snippet]] Verify the Register Output: With the above modification, the output of the shell task should now contain the filename of the created CSV file. When Ansible executes the register: fsdetails_files_to_copy, stdout_lines will hold the name of the file you need. Keep the Fetch Task Unchanged: You won’t need to alter the fetch task in this case, as it should now work correctly. The fetch block remains: [[See Video to Reveal this Text or Code Snippet]] By implementing these changes, you ensure the correct CSV file is echoed and available for the fetch task to execute successfully. Conclusion In summary, the issue arose because your original command was not returning the output needed for subsequent tasks. By making the echo command part of your shell task, you can manage to get the correct filenames that the fetch module needs, ensuring a hassle-free transfer of files from node servers back to your control machine. If you find yourself facing this error in the future, remember this simple adjustment to your Ansible playbook, and you’ll be set for successful file transfers every time!
