[FIXED] JGI data loss in /projectb/sandbox area [purge]

August 19, 2013 by Kjiersten Fagnan

We have discovered a serious bug in our purge scripts on /global/projectb. The */global/projectb/sandbox* areas are supposed to be immune from the purge (like the project directories); however, there is a bug in the purge script that caused some files to be deleted if they had not been touched for 90+ days (like data in the scratch directories). *The sandbox areas are not backed up*, so if this data was not in more than one location on disk or in HPSS, it has been lost. We have found the bug and have suspended the purge script until the bug is fixed.

Update: The purge system has been repaired.  /global/projectb/sandbox is no longer being purged.
