The Core Filesystem (/asap3/<facility>/gpfs) is accessible via several protocols. Accessing the Core filesystem is only possible from within the DESY network and always requires a valid DESY account.
The Core filesystem is mounted on the Maxwell Analysis cluster. For more information, see Maxwell for Photon Science
For Windows, macOS and Linux users from Office networks, SMB is the recommended way to access the Core filesystem.
Linux desktop users should also access the Core filesystem via SMB, as it does not require any root permissions or configuration on the clients.
This is currently the only way to mount the Core filesystem on a DESY green desktop installation.
Each individual facility or research group has its own share:
|Facility||Path on GPFS||Share Name|
|Research Group||Path on GPFS||Share Name|
While SMB is still the recommended way to access the Core filesystem, certain use-cases require an NFS mount.
For this purpose, an NFSv4 export with and without Kerberos is available.
|Facility||Path on GPFS||NFS Export|
|Research Group||Path on GPFS||NFS Export|
Mounting the Core filesystem via Kerberos requires root privileges on the client machine.
Additional configuration and a kerberos keytab is required on the client machine, this out of scope for this documentation.
Mounting the Core filesystem without Kerberos requires root privileges. Due to the security implications for this type of mount, this must be explicitly requested, as the host will be included in a whitelist.
Please contact FS-EC (firstname.lastname@example.org) in order to be included in the whitelist.
Additional configuration is required on the client machine, this is out of scope for this documentation.
