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 |
|
FLASH | /asap3/flash/gpfs/common | \\asap3.desy.de\flash-common |
| Special Instruments | /asap3/spec.instruments/gpfs/common | \\asap3.desy.de\spec.instruments-common |
| Research Group | ||
| FS-FLASH-O | /asap3/fs-flash-o/gpfs/common | \\asap3.desy.de\fs-flash-o-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 |
For a pictured manual to map network drives, please refer to Data Access: Core FS. The steps are the same, just different share names have to be used for common.
Windows 7 EOL
Windows 7 has reached end of life on 2020-01-14, no security updates are available anymore.
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.
| Facility | Path on GPFS | NFS Export |
|---|---|---|
PETRA III | /asap3/petra3/gpfs/common |
|
FLASH | /asap3/flash/gpfs/common | asap3.desy.de:/common/flash |
| Special Instruments | /asap3/spec.instruments/gpfs/common | asap3.desy.de:/common/spec.instruments |
| Research Group | ||
| FS-FLASH-O | /asap3/fs-flash-o/gpfs/common | asap3.desy.de:/common/fs-flash-o |
| FS-DS-AGIPD | /asap3/fs-ds-agipd/gpfs/common | asap3.desy.de:/common/fs-ds-agipd |
| FS-DS-Percival | /asap3/fs-ds-percival/gpfs/common | asap3.desy.de:/common/fs-ds-percival |
Restricted Mount Access
Access to the NFSv4 exports are restricted by IP subnet.
For PETRA III, the following subnets are allowed to mount the read-only common folder filesystem without kerberos:
Mounting via NFSv4 without Kerberos
Mounting the common folder requires root privileges. On Linux installations at the beamline, common is usually already mounted.
Please contact FS-EC (fs-ec@desy.de) in case of problems.
mount without krb5
mount -o ro,nfsvers=4,sec=sys,hard <NFS Export> <local mountpoint>
Example
mount -o ro,nfsvers=4,sec=sys,hard asap3.desy.de:/common/flash /common
Additional configuration is required on the client machine, the setup for this is out of scope for this documentation.
