| − | <b>Tue Feb 28 2017 16:00:00 EST</b> The file transfer of users files on the old scratch system to the new scratch system has been completed. The new scratch folders are logically in the same place as before, i.e. /scratch/G/GROUP/USER. Your $SCRATCH environment variable will point to this location when you log in. The project folders have also been moved in the same way. Compute jobs have been released and are starting to run. Let us know if you have any concerns. Thank you for you patience.

| − | <b>Tue Feb 28 2017 10:02:45 EST</b> It could take a few more hours for the scratch migration to finish. We still have a dozen or so users to go. Please check this page from time to time for updates.

| − | <b>Mon Feb 27 2017 10:00:00 EST</b> The old scratch was 99% full. Given the current incident of scratch getting unmounted everywhere, we had little choice but to decide that it is time to initiate the transition to the new scratch file system at this point, instead of performing a roll-out approach that we had planned earlier.
| |
| − | | |
| − | We estimate the transition to the new scratch will take roughly one day, but since we want all users' data on the old scratch system to be available in the new scratch (at the same logical location), the exact duration of the transition depends on the amount of new data to be transferred over.
| |
| − | | |
| − | In the meantime, no jobs will start running on the GPC, Sandy, Gravity or P7.
| |
| − | | |
| − | In addition, $SCRATCH will not be accessible to users during the transition, but you can login to the login and devel nodes. $HOME is not affected.
| |
| − | | |
| − | The current scratch system issue and the scratch transition don't affect the BGQ or TCS anymore (although running jobs on TCS may have stopped this morning), because BGQ and TCS have their own separate scratch file systems. It also does not affect groups whose scratch space is on /scratch2.
| |
| − | | |
| − | <b>Mon Feb 27 2017 7:20:00 EST</b> Scratch file system is down. We are investigating.

| − | | |
| − | <b>Wed Feb 22 2017 16:17:00 EST</b> Globus access to HPSS is currently not operational. We hope to have a resolution for this soon.
