Group drives (CIFS/NFS)

General information

An area for joint projects is provided for each structural unit (group) in OVGU's central storage system. The structure is based on the LSF.

The storage area is synchronously mirrored across the two locations of the University Computer Center.

Detailed instructions and help with problems can be found in our FAQ (german).

Access rights

The users are assigned to the corresponding groups according to their cost center(s). Local groups can be created and maintained at https://wlux.urz.uni-magdeburg.de/localadmin by the IT officers of the structural units. The rights for the subfolders can be set in fine granularity on a group or user basis.

Detailed information can be found on the page Group access rights

Establishing a connection

In the address bar of Windows Explorer, enter the address in the following format: \\stgroup.ovgu.de\group\FACULTY\INSTITUTE\
macOS users enter the address in the following format:

smb://stgroup.ovgu.de/group/FAKULTÄT/INSTITUT

Example:

\\stgroup.ovgu.de\group\fmb\ilm\

The NetApp integration for Ubuntu systems is described on this page.

Please note: If you do not log in to your computer with your OVGU-Account, you must enter the domain @ads.uni-magdeburg.de after your user name. Do not just enter jdoe, but jdoe@ads.uni-magdeburg.de instead.

For access via NFS, the client must use the Kerberos servers of the University Computer Center (lem, bowles, strugazki). Furthermore, an NFS service ticket for the /etc/krb5.keytab is required, which is issued by the URZ. Only NFS version 4.1 is currently available.

mount -o nfsvers=4,minorversion=1,sec=krb5 stgroup.ovgu.de:/group /import/group<br>mount -o nfsvers=4,minorversion=1,sec=krb5 stgroup.ovgu.de:/group/ze/urz /mnt<br>mount -o nfsvers=4,minorversion=1,sec=krb5 stgroup.ovgu.de:/group/fmb/ilm /mnt

Quota

100GB per default via Qtree for institutes and central facilities
can be adjusted individually and globally
Additional volumes can be mounted if required

Backup

Snapshots for restoration by the users themselves:

one snapshot per hour is taken for the last 24 hours, a total of 24
one snapshot per day is kept for the last week, a total of 7
only one snapshot per week is kept for the last 3 months, a total of 14
if the data change rate is high, the storage time can be shortened or the space for snapshots can be increased

In addition, the URZ carries out backups for disaster recovery.
