Common

The common folder of the Core filesystem (/asap3//gpfs/common) is accessible via several protocols.

If you want to mount the common folder on the beamline for read-only access, follow this guide.

For modifying content in the common folder, please see Data Access: Core FS. Common can only be modified by accessing the Core filesystem directly.

Access Methods

SMB - For Windows and macOS users

For Windows and macOS users, the common folder can be mounted via an SMB share.

Each individual facility or research group has its own share:

Facility Path on GPFS SMB Share Name
PETRA III /asap3/petra3/gpfs/common \\asap3.desy.de\petra3-common
FLASH /asap3/flash/gpfs/common \\asap3.desy.de\flash-common
Special Instruments /asap3/spec.instruments/gpfs/common \\asap3.desy.de\spec.instruments-common
Research Groups Path on GPFS SMB Share Name
FS-FLASH-O /asap3/petra3/gpfs/common \\asap3.desy.de\petra3-common
FS-FLASH-B /asap3/fs-flash-b/gpfs/common \\asap3.desy.de\fs-flash-b-common
FS-DS-AGIPD /asap3/fs-ds-agipd/gpfs/common \\asap3.desy.de\fs-ds-agipd-common
FS-DS-Percival /asap3/fs-ds-percival/gpfs/common \\asap3.desy.de\fs-ds-percival-common
FS-LA /asap3/fs-la/gpfs/common \\asap3.desy.de\fs-la-common
FS-SC /asap3/fs-sc/gpfs/common \\asap3.desy.de\fs-sc-common
it-sci /asap3/it-sci/gpfs/common \\asap3.desy.de\it-sci-common
nanolab /asap3/nanolab/gpfs/common \\asap3.desy.de\nanolab-common
cfel-cmi /asap3/cfel-cmi/gpfs/common \\asap3.desy.de\cfel-cmi-common
FS-BMX /asap3/fs-bmx/gpfs/common \\asap3.desy.de\fs-bmx-common
ikz-xro /asap3/ikz-xro/gpfs/common \\asap3.desy.de\ikz-xro-common
Rock-It /asap3/rock-it/gpfs/common \\asap3.desy.de\rock-it-common

For a pictured manual to map network drives, please refer to Data Access - Core FS. The steps are the same, just different share names ahve to be used for common.

Note

The SMB service only allows connections from machines, which implement SMB2 or higher. SMB2 is available for recent Windows versions (Windows 7 and newer) and modern Linux distributions. Some Linux tools might need additional configuration options to use SMB2, e.g. smbclient can be forced to use SMB2/3 by setting -m SMB3

Danger

Windows 7 has reached end of life on 2020-01-14 and no longer receives any security updates. Access via SMB from Windows 7 hosts is therefore no longer supported.

NFSv4 - For Linux users

For Linux users on the beamline, common folder can be mounted read-only via NFSv4 without kerberos.
