Ares was recently equipped with a new filesystem, which will take over the role of the scratch space. The new filesystem is significantly faster and allows for significant advancement in greatly improves computing efficiency. This  This advantage comes at the cost of the reduced maximum size of the scratch space, don't hesitate to contact the helpdesk if this is a significant issue in your case. To fully utilize the new filesystem, we've updated the data retention policy, please consult the information below. New scratch is currently available in early access mode. Both storage systems, new and old, will function for a certain period so that the migration process can go smoothly without interruption of work. Instructions on how to use the new filesystem are included below. In the near futureSoon, the new scratch filesystem will be the default, and the old scratch will be decommissioned. If you choose to use the new scratch space, please don't intensively use the old one.Please note that the new filesystem is still being tuned and optimized, and periods of reduced accessibility might occur

Migration timeline:

• 01.01.2025 - The old $SCRATCH space will be switched to read-only mode. All user accounts will be switched to using the new scratch space by default.
• 17.01.2024 - The old $SCRATCH space will be disconnected from the cluster nodes.

Naming convention

The filesystems were named as follows:
