Dear users of cyclone,

We will have an emergency downtime until further notice because of issues with the Lustre filesystem on Please, save any work and log out.

Feel free to contact us via if you have any questions.

Apologies for the inconvenience.

Update 18.06: cyclone is up and running. Yesterday we thought that there might be something wrong with the local Lustre filesystem, which includes /home and /Data/gfi/stormrisk. To reduce the risk of data loss, we brought the systems offline. However, everything appears to be working reliably after all.
In addition, the backup of /home does not always finish. We are still looking into this problem, but you may login and use cyclone again.

Best regards,

The IT department and the Scientific Computing Group

Dear users of cyclone and Ubuntu,

A large part of the data under /Data/ is being migrated to the central IT department storage place. To finish the migration, this Tursday between 9:00 and 15:00 paths below /Data/ won't be accessible all the time (or at least not writable).

Hereafter, on both the Ubuntu clients and on cyclone, all your files are still available under the regular /Data/gfi and /Data/skd paths you're used to. On Windows the new locations will be as follows:


For your convenience, you can map each to a drive letter by following this HOWTO.

On the Wiki there is more detailed information on GFI & SKD Storage.

Feel free to contact us via if you have any questions.

Update 28.05 : The data migration is finished and all Linux and Window paths with the new destinations should be accessible.

Best regards,

The IT department and the Scientific Computing Group
