[Restored] GPFS Filesystem Issue

Filed under: Uncategorized — Michael Weiner @ 5:45 pm

We are happy to report that our GPFS filesystem was restored to functionality early this afternoon. Our CI team was able to identify a failed switch as the source of problems on a group of nodes. We restored the switch, and we are investigating the deployment of improved backup systems to handle such cases in the future.

We apologize for the recent issues you have faced. As always, please send an email to with any concerns, so we can investigate.

We have been experiencing intermittent disruptions on our GPFS filesystem, especially on the mounted GPFS scratch (i.e., ~/scratch) filesystem, since yesterday. The PACE team is actively investigating the source of this issue, and we are working with our support vendor to restore the system to full functionality. A number of users have reported slow reads of files, hanging commands, and jobs that run more slowly than usual or do not appear to progress. We apologize for any interruptions you may be experiencing on PACE resources at this time, and we will alert you when the issue is resolved.
