Description
In 2024, the CTA Tape Daemon was updated to address issues in deployments with multiple drives per tape server. This was a first step towards a major refactoring of the daemon, as in its current state, its multi-process architecture presents problems such as logging information unrelated to the current process and inter-process communication bugs. It also causes confusion in internal discussions and in external bug reports.
In this session, we will provide an update on the current state of the CTA Tape Daemon, explore the upcoming changes designed to reduce the daemon's complexity by removing its parent-child process architecture, and promoting the maintenance process to an independent daemon, as it doesn't perform any drive related tasks. We will conclude with a discussion of possible future developments.
