More Rackham storage in Spring 2022

UPPMAX has laid an order for 3.75 PB of effective storage that will be added to the Crex storage system in the Spring of next year. This will bring the total volume of storage available on Rackham and Snowy to about 9.75 TB. Part of this space is reserved for system software and central databases, and available quota for projects is expected to increase by over 50%. This should be sufficient until the planned end-of-life of Rackham and Crex at the end of 2024.  Until the extension is in place, space on Crex is very tight. Please continue to delete unnecessary files, be patient with performance degradations, and please wait until Spring before generating significant amounts of new data.
