Mass Storage (/pnfs) /pnfs has sometime issues

Hello,

For the last few days, /pnfs is having performance issues, while some storage nodes can't serve files. We have not identified the cause yet.

Mainly cd/ls becomes slow, and only a restart of the service makes it work fast again. Also, a couple of storage nodes have a hard time serving files (hence why some of your files have issues), this usually solves itself after a while.

Cheers, The T2B IT Team

Batch System Batch System is down - no qsub possible

The batch system software is currently failing to restart. We are investigating. No local submissions are possible. Grid jobs will continue running.

  • Batch service is back. Unfortunately all jobs were purged during the investigation, so you will have to resubmit your jobs.

    The issue was due to a remnant job file defined as array that created a segmentation fault, probably because the batch software could not handle the number of created jobs by the array. Once the file was removed, the batch system did not crash during start anymore.
