Short hiccup NFS

  1. Cause likely found

    This issue re-occurred again at 21:13 and resolved itself at 21:15.

    Based on debug logging, we've likely found the cause: a deadlock in the NFS kernel process.

    We're going to do further research first thing tomorrow and, if needed, announce maintenance for a fix.

  2. Issue automatically resolved

    The hiccup started at 21:06 and resolved itself at 21:10.

    For an unknown reason, the storage server seems to stop processing I/O requests for a short while.

    We are investigating the issue and will follow up here as soon as possible.

  3. Happening again

    We are seeing this issue again and are debugging it.

  4. Backup moved

    The backup process has been moved to run at night.

  5. Short hiccup detected & fixed

    A short hiccup occurred on a shared storage server caused by a running backup. The backup process has been stopped to fix the interruption. Clusters using this storage server might have see impact  

    We’re going to move the backup to run at night.
