We have a major maintenance to upgrade the Lustre parallel file system (/pfs/nobackup).
One of the goals is to introduce new functionality, for instance project based storage.
We will also do a number of related changes and optimizations to the Lustre file system setup.
We are planning for a full week of complete downtime on all HPC2N systems, including login and thinlinc nodes, starting 2018-06-04 07:30 CEST.
Please make sure to copy any files you want to work with during the downtime to some other system well in advance of the maintenance.
