The Luster filesystem "/lustre" is close to be saturated (in terms of inodes). If the system reaches the saturation, creation of new files on /lustre will no longer be possible.
It is therefore necessary for each user to clean up his personal directory /lustre/<LOGIN>.
We remind you that the storage space /lustre is a temporary work area and is not saved.
To store your non-temporary and big data, it is also possible to use the iRODS service. Information on it is available here: https://www.plafrim.fr/en/irods-storage-resource/
We will implement a quota in terms of number of file per user (~ 400 000).
Thank you for your understanding,
