Filesystems

This section provides information about the various storage areas (filesystems) available on the CSF. Please choose from the menu on the left.

The scratch filesystem should NOT be used for long-term storage. Files unused for 3-months or more can be deleted automatically by the system.Unused files are those that have not been read or written to, by you or your jobs.

But all users must monitor and manage their own scratch usage – do not simply rely on the scratch-tidy to do it for you!

There is NO backup of the scratch area. If you, or the automatic clean-up, deletes files, they are gone forever!

Ensure you copy important results back to your home area or additional research data storage – these areas are backed up. Please read the pages in this section for more information.

Introduction

There are several filesystems on the CSF. They provide you with storage for you files and directories (also known as “folders”), and have different properties. For example, some storage is faster (to read from and write to) than others. Some storage is backed up. Some is visible across all compute nodes and login nodes, where as some is only visible to a running job for the duration of that job.

The pages in this section describe the available storage to you.
