 We realize you all have different needs in terms of storage. To guarantee storage space for all users, we have **set a quota on home and scratch directory**, see table above for details. Beyond this limit, you will not able to write to this filesystem. We count on all of you to only store research data on the clusters. We also count on your **to periodically delete old or unneeded files** and to **clean up everything when you will leave UNIGE**. Please keep on reading to understand when you should use each type of storage.

 The EESSI did a nice tutorial about CVMFS readable on [[https://multixscale.github.io/cvmfs-tutorial-hpc-best-practices/|multixscale]] git repo.
+===== EOS =====
+You can mount root filesystems using EOS.
+<code>
+(bamboo)-[sagon@login1 ~]$ export EOS_MGM_URL=root://eospublic.cern.ch
+(bamboo)-[sagon@login1 ~]$ export EOS_HOME=/eos/opendata

+<note important>do not mount the filesystem in your home or scratch space as it isn't working because they aren't standard filesystems</note>
 ====== Robinhood ======
 Robinhood Policy Engine is a versatile tool to manage contents of large file systems. It daily scans the scratch beegfs filesystems. It makes it possible to schedule mass action on filesystem entries by defining attribute-based policies.
