Only computers which have their IP address registered for the beamline will be able to mount the beamline file-system.

The IP address should be register with FS-EC. This is especially important for Pool Detectors. 

Share Creation on Windows

The ASAP3 storage system should be mapped to T and U. For these drives the virus scanner has been turned off via policy settings to prevent it from scanning the whole file-system.

Share for the storage system

  • right-click on "Computer"
  • click on "Map network drive"
  • choose drive T:
  • choose folder \\<Beamline specific SMB Server>\<Beamline>
    e.g for P10: \\asap3-p10.desy.de\p10

Note for Windows 10

  • In order to mount the storage system from a DESY Windows 10 host, you have to use a valid DESY account
    • Usually this is <Beamline>user, e.g. p10user at beamline P10
  • Mounting the storage with the guest account is longer possible with a DESY Windows 10 installation, as the account is disabled by default.
  • For non-DESY Windows 10 installations, mounting with guest permissions might work
    • Otherwise, contact local staff in order to mount the share with a valid DESY account

Note for Windows 7

  • Windows 7 will reach end of life on 2020-01-14 and will no longer receive security updates
  • Access via SMB from Windows 7 hosts is no longer supported

Share for the common directory

  • right-click on "Computer"
  • click on "Map network drive"
  • choose drive U:
  • choose folder \\asap3-smb.desy.de\common

 Share for the documents directory

  • right-click on "Computer"
  • click on "Map network drive"
  • choose drive V: (t.b.c, not yet registered as non-virus-scanned!)
  • choose folder \\<Beamline specific SMB Server>\bldocuments-<Beamline>
    e.g for P10: \\asap3-p10.desy.de\bldocuments-p10  Note that beamline names with a dot (.) are mapped to server names with a dash(-), e.g. p21.1 → asap3-p21-1.desy.de
  • The documents directory has snapshots, which can be accessed in windows explorer via right-click → restore previous versions.

Mounting on Linux

If the IP address was provided to FS-EC the mount points will have been set in fstab. You will then find the beamline file-system under /gpfs and the common directory under /common.

If the IP address was provided but the file-system is not there, it can be mounted as described below.


Mounting the storage system

For NFS mounts on Linux, please use the following mount options:

mount -o nfsvers=3,rsize=65536,wsize=65536,hard <Beamline specific NFSv3 Server:Path>


 mount -o nfsvers=3,rsize=65536,wsize=65536,hard asap3-p10.desy.de:/beamline/p10 /gpfs


Note: for mounts on MAC OS, you typically / most likely have to add the option 'resvport' as well.

Mounting the common directory

 

directory common to all beamlines is available for providing read-only access to scripts, documentation, calibration files, etc ...

 

For NFS mounts on Linux, please use the following mount options:

 

mount -o nfsvers=3,rsize=65536,wsize=65536,hard asap3-nfs.desy.de:/asap3/<facility>/gpfs/common /common

 Mounting the documents directory

The documents directories are mounted like the storage system, except that

in the  paths given in the table on the right one has to replace beamline with bldocuments.

This directories are beamline-specific and provide snapshots.

To access the snapshots in every (sub)directory there is a hidden .snapshots directory, (hidden means: it does not show up even via ls -a) which can be accessed using the name (eg. ls /bl_documents/mystuff/.snapshots will show you the snapshots of you mystuff directory, with an obvious syntax like @GMT-2017.05.10-22.30.01)


 mount -o nfsvers=3,rsize=65536,wsize=65536,hard asap3-p10.desy.de:/bldocuments/p10 /bl_documents

Allowed Hosts for Beamline Filesystem

The allowed hosts to access the beamline filesystem are stored in LDAP. If you are unsure, if your PC has access to the beamline filesystem, the DESY LDAP server can be queried.

If the host is not in the list, please get in touch with FS-EC to register the host.

Query from Linux

In order to query the DESY LDAP server, access to the DESY network and the command line tool "ldapsearch" is required:

ldapsearch -x -H ldap://it-ldap-slave.desy.de:1389 -b ou=rgy,o=DESY,c=DE -LLL cn=a3<beamline>-hosts

Substitute <beamline> with the lower-case name of your beamline, e.g. BL1 → bl1, P11 → p11
The output will contain a nisNetGroupTriple, for each configured host for the beamline filesystem.

$ ldapsearch -x -H ldap://it-ldap-slave.desy.de:1389 cn=a3bl1-hosts -LLL
dn: cn=a3bl1-hosts,ou=netgroup,ou=rgy,o=desy,c=de
