Known Issues and Limitations

  • Create/Update/Delete of container NFS Exports is currently only possible via a service request on the LRZ Servicedesk.
  • Restore of backed-up/archived data is currently only possible via a service request on the LRZ Servicedesk.
  • DSSWeb can only be accessed from within the Munich Scientific Network (MWN).
  • DSSWeb Webinterface may not work correctly when opened in multiple browser tabs.
  • DSSWeb accepts invitations for deleted users, causing invitation acceptance to crash.
  • Deleting an accepted invitation of a user with quotas does not unset the user quota on the ISS fileset.
  • Raising the Inode limit of a container does only increase the ISS fileset quota but not the max Inode limit of the ISS fileset itself.
  • After accepting an invitation or doing the first time Globus registration, it can take up to two hours until the user is enabled for the Globus platform.
