File Service for UNIX/Linux
Storage for UNIX/Linux file service is automatically assigned to each GWDG account. This storage can be accessed via dialog or samba server or using the parallel computers.
Almost the entire UNIX/Linux hosts within the GWDG use the global file systems StorNext. The directories are in general, shared simultaneously on multiple systems accessible by users via the NFS protocol.
Individual user directories can be exported to a UNIX/Linux system within an institute using NFS if the performance requirements exceed the access using a the samba server. You can request the NFS export by sending an E-Mail to Support@GWDG.de
In a UNIX/Linux dialog session the file service is structured by the following three environment variables:
|Variable Access||Description||Default Size|
|Home directory for constant data.||25 GB|
|Home directory for temporary data, |
which is generally deleted by GWDG after a week.
|Home directory on the archive server.||unlimited|
After a successful login the user will be placed into his or her home directory
There UNIX commands can be invoked.
If the assigned storage (by default 25GB / 6GB) is not sufficient an informal request for expanding the quota can be sent to Support@GWDG.de.
$THOME is to be used for saving files temporarily. Please note that in
$THOME aged one week or more will be erased automatically without notification. In order to use
$THOME via the samba server the following commands must be executed on a dialog server. (This has to be done only once.)
cd $HOME ln -s $THOME ./thome
If files need to be archived in order to keep free space at your
$HOME director they can easily be moved to
$AHOME using UNIX commands.
