Access and security
Groups that use the iiStore
cluster for file services need to be aware of the customization options and configuration of their storage.
The number of filesystems and their size depends on the amount and type of data:
- The maximum supported size of a file system is about 1TB. If there is more data it needs to be distributed in a meaningful fashion over several filesystems. Larger filesystems are technically possible but are difficult to handle for backup and recovery operations (e.g. fsck).
- Groups that have project directories and want to control data usage using disk quota are advised to put home directories and project data on separate filesystems.
Service Host Name
The data of a particular group is accessed using a dedicated IP with one or more host names. The default is
is replaced by the LDAP OU of the group, e.g.
A unique IP with one or more host names is also used to access the snapshots. In this case the default is
By default all home directories are exported individually using a unique netgroup that can be customized by the user
or by IT Coordinators
. Export of other data is managed by isginf
Access to data exported by NFS is only restricted by IP addresses. We advise you not to put sensitive data such as exam questions and solution, password files or sensitive personal information in places that are exported via NFS.
For groups that do not use NFS, e.g. groups that exclusively use Windows, we recommend to disable NFS. Individual users can also empty their personal netgroup
to prevent access via NFS to their home directories.
All data is by default also shared with SMB/CIFS. The share names for data other than user data can be defined by the group.
