BwUniCluster2.0/File System Migration Guide

This page describes changes on the file systems between bwUniCluster 1 and bwUniCluster 2.0.

1 Lustre file systems

With bwUniCluster 2.0 new file systems for $HOME and workspaces have been purchased. The user data of the corresponding old file systems has been copied by KIT/SCC to these new file systems. The content of $WORK has to be migrated manually by the users to workspaces during the next 4 weeks, for details see below.

1.1 What has changed on $HOME and workspace directories?

You should see the same data as before but if this is not true - which is possible in rare cases since the data of expired users has been cleaned up - please contact the hotline or open a ticket. The virtual path to $HOME (/home/ORG/GROUP/USER) is still the same (except for University of Stuttgart users, see below) but the physical path (which can be seen by /bin/pwd) has changed. If one of yours scripts includes a physical path (wich is not recommended) you should modify these scripts. If applications complain about the old physical path (which started with /pfs/data1/ or /pfs/data2/) you should modify or recompile the application.
