Over the past several months, a huge amount of data (491 TB) has accumulated in the /scratch directory on the Flux computing cluster. /scratch is meant for data relating to currently running jobs, and the buildup of data is threatening the performance of Flux for all users. Therefore, ARC will begin deleting data from /scratch that have not been accessed for 90 consecutive days. Flux account owners with unused data have begun receiving emails warning that their data will be deleted. Account owners in this situation can move their data to another system such as ITS Value Storage or their own equipment using the dedicated transfer nodes on Flux with high speed network connections available for that purpose. For more information on Value Storage, see the ITS website. For more information on transfer nodes, see the ARC website. If you have any questions, please contact email@example.com.
