Hardware provisioning for CTA
/ Leduc, Julien (speaker) (CERN)
The CERN Tape Archive (CTA) was designed to meet the demands of data archival from the LHC experiments, in terms of both data volume and throughput. In order to ingest data at the rates demanded by the LHC data acquisition (DAQ) systems, the system is built on EOS and CTA's scalable architecture principles. [...]

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. [...]
