Configuring ATRESYS to use Repack tapepools
/ Larbi, Idriss (speaker)
Until now, repack and archival of new files were carried out on the same tapepool. This could lead to the user's new archive files being mixed on the same tape as the old repack files, reducing performance during retrieve. [...]

Advancements in FSCK for EOS
/ Del Monte, Gianmaria (speaker) (CERN)
One of a critical components in EOS is fsck, responsible for scanning, verifying, and repairing inconsistencies in the filesystem.
This talk will provide an in-depth exploration of fsck in EOS, covering its architecture, scanning mechanisms, and repair strategies. We will discuss recent improvements, including the introduction of a best-effort mode, and enhancements in erasure-coded file scanning, which significantly boost performance while minimizing the impact on the running instance..

A Distributed Probe for EOS: Real-Time Availability Monitoring and Alerting
/ Del Monte, Gianmaria (speaker) (CERN)
Ensuring the availability of EOS instances is crucial for large-scale storage operations. To enhance monitoring and incident response, we have developed a new distributed probe designed to detect and alert operators about instance malfunctions in real-time.
This talk will introduce the architecture and functionality of the probe, which runs across multiple nodes to provide redundancy and reliability. [...]

CTA Tape Daemon Evolution
/ Oliver Cortes, Pablo (speaker) (CERN)
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.
