Changes

Currently, there is sufficient space left, however, I kindly ask you to not keep data you do not use anymore on the Ceph filesystem for too long. In particular, please delete old checkpoints of training runs you will never need again - I have seeen people use hundreds of Gigabytes for their training histories. If you still need these, please move them onto your own computers. If you really want to keep old stuff lying around on the cluster filesystem, maybe because you are not sure whether you will need it again later on, then please put it into a folder which is not backed up. For this, every user can mount the Ceph directory

which can be used as an archive. Make sure that the directory is created if it does not exist, by specifying "type: DirectoryOrCreate".
