Replacement of BeeGFS by GPFS (DUST)

BeeGFS will be retired very soon, and replaced by a GPFS based storage system called DUST.

We (the Maxwell team) will take care of the migration from BeeGFS to dust. BeeGFS will not be shutdown and BeeGFS directories WILL NOT BE DELETED before all data have been transferred to DUST, and everyone is sufficiently happy with the setup.

There are two major branches on the BeeGFS storage system:

  • the user directories under /beegfs/desy/user/
  • the group directories under /beegfs/desy/group/

We will first migrate the user-directories before starting with the migration of group folders.

User space migration

everyone with a folder in /beegfs/desy/user/ should have received an email explaining the procedure:

Dear BeeGFS user!

You are owner of the folder /beegfs/desy/user/<user>. This folder will be deleted till end of the year.

On Monday, 9.12.24, we will start to migrate the user directories from BeeGFS to DUST, if requested

          /beegfs/desy.de/user/<user> => /data/dust/user/<user>/beegfs.migration

IMPORTANT:
Please fill out the following survey to let us know what should happen to your data.

https://wiki.desy.de/survey/

We will transfer the group directories at a later date, there will be a separate email.

The survey gives three options:

  • I currently do not need a directory in the DUST filespace. My BeeGFS directory /beegfs/desy/user/user can be deleted.
    • /beegfs/desy/user/user will be removed. IT CAN NOT BE RESTORED AFTERWARDS!
    • No DUST folder will be created
  • I need a directory in the DUST filespace. My data in the BeeGFS directory /beegfs/desy/user/user can be deleted, and the directory can be removed.
    • /beegfs/desy/user/user will be removed. IT CAN NOT BE RESTORED AFTERWARDS!
    • A DUST folder will be created with a quota of 1TB
  • I need a directory in the DUST filespace. My data in the BeeGFS directory should be moved to the DUST user directory.
    • A DUST folder will be created
    • Data will be moved from BeeGFS to /data/dust/user/user/beegfs.migration. WE WILL TAKE CARE OF IT!
    • We might get in touch with you before starting the migration, if the volume of your BeeGFS folder exceeds 5TB.

Please fill in the survey if you haven't done yet!

Group space migration

Migration of /beegfs/desy/group will start once the user directories have been migrated. Groups will be informed beforehand.

Terms of use

the space on DUST has pretty much the same terms as the BeeGFS storage. It's temporary storage

  • without any backup or snapshots. A file deleted is gone forever
  • files in user space without an owner (e.g. the owners account expired) will be deleted without prior notice.
  • files in group space without an owner have to be adopted - or will be removed
