We recognize and understand the frustration that the scratch situation has caused for many users. We are giving this issue the highest priority. Our intention was to move to an appliance-based vendor solution which could be leased and replaced regularly. The original DDN appliance, scratchlfs, had severe stability issues which could not be resolved by their engineering team. The vendor then deployed an all-new pre-tested system, scratchlfs02, to try to remedy this, but this system still has not remained stable and performant enough to serve as fast scratch in our environment.
- The original appliance /n/scratchlfs (and /n/scratchssdlfs) will be shut down during this maintenance
- /n/scratchlfs02 remains online and and the $SCRATCH environment variable remains pointed to it until March 2nd
- The new FASRC-built scratch will be available for use on or before February 3rd
- scratchlfs02 will be decommissioned March 2nd and $SCRATCH will be pointed to scratchlfs04 on that date
