As most of you know, the scratchlfs system has exhibited performance issues and instability for some time. We're pleased to announce that a replacement system has been delivered, built, tested, benchmarked, and is ready for your use now at /n/scratchlfs02 .

 

Along with regular monthly maintenance on January 13th, 2020 ( https://www.rc.fas.harvard.edu/monthly-maintenance ), some changes around scratch space will occur.

 

* The new scratch filesystem is now online at /n/scratchlfs02 - During the next monthly maintenance period on January 13th, 2020, we will re-point the $SCRATCH variable to this new filesystem.

 

* At that time, scratchlfs and scratchssdlfs will be set to read-only to allow you to copy any data you need to the new scratchlfs02 filesystem. Please do so sooner rather than later as /n/scratchlfs (and scratchssdlfs) will be shut down and returned on Feb. 3rd, 2020.

See: https://www.rc.fas.harvard.edu/resources/documentation/transferring-data-on-the-cluster/

 

* Those who used the temporary scratchlfs04 space, your data was relatively small overall and has already been moved to scratchlfs02. Please begin using scratchlfs02 ASAP..
