The Premise HPC cluster is in need of a scheduled downtime for reconfiguration, migration to the new storage, and general system upgrades. We hope that by scheduling a month out people can work around these dates, and that Premise will be ready for the many jobs expected during the long holiday break.

Our plan is to shutdown first thing Monday morning 12/16. The main upgrades will occur on Monday. We will then work to migrate as much data as possible from Lustre to the new BeeGFS storage. We have moved over the data multiple times, but it gets immediately stale with every job output you run.

Given the size of the data storage on Premise there is little chance we can complete all the migrations within a three day window. We will start with the smallest groups and provide detailed status update for the larger groups on the 18th.

1. Cleaning up anything currently stored on Premise that you do not need. This would be a great chance to ensure the 2nd copy of your data is complete.

2. "STATIC" If you store a lot of data on Premise please let us know the areas that we can copy now that will NOT have to be updated later. If you have any large datasets that need to be moved but will not change please provide the path to them so we can copy them in the weeks before 12/14 and NOT attempt to update them during this short window. If in doubt provide the path, as we are not reformatting the old storage immediately, so it will be available to us for awhile AFTER this planned storage migration window.

3. "CRITICAL" On the other hand if you have critical area that you really need, please provide the path(s) so that we can ensure it is moved during the scheduled 3 day window. This only makes sense if your group has multiple TB of storage on Premise, smaller groups (<5TB) do not need to specify their critical areas, since we will have time to easily move your entire group area.
