Storage

In terms of data storage, the Linux users have available:

  • home directory disk space. Data can be stored permanently there (/home/zmaw/<user-id>) up to the amount of 20GB. The disk space is backed up, so, in case of an emergency, old versions of files can be restored. To check the amount of space consumed use the command “quota”.

  • local disk space. If the user works on a dedicated Linux workstation there will generally be disk space under /scratch/local1 and/or /scratch/local2. There is no backup of data under /scratch, so data is lost in case of hard disk failures or accidental deletion of files.

  • project disk space. Under /data/share there is additional project disk space. The user can only store data in the project/group he/she belongs to. Additionally, if the user is connected to a central server (“marin”) there is disk space under /scratch. That disk space belong also to specific projects/groups. The files under /scratch have no backup.
