TFACTL Collection Errors: "METADATA JSON FILE ALREADY EXISTS" in tfa_main.trc

Description: Manual collections that start simultaneously or within the same second on the same or different nodes may encounter issues in some collections.

Cause: This issue occurs when multiple manual collections are initiated across nodes at nearly the same time. Since the .zip.json file is created in the collection directory and assigned the same tag, one collection process generates the file first, while others fail with the "METADATA JSON FILE ALREADY EXISTS" error. The validation step might be skipped due to the near-simultaneous execution, even if the temporary directories differ.

Action: To avoid this issue, start multiple collections on different nodes using the tag option. For example, adding the following tag:-tag _#TFADEFAULTTAG#

This ensures that the collection directory follows a unique naming format, such as: atpd-exa-aq5hx4_collection_Tue_Nov_26_03_45_00_UTC_2024_node_all
