    Our tier 3 tape system is part of and run by NESE (the NorthEast Storage Exchange).

    We have been informed that they will be installing additional tape drives to the system on July 21st and this will require a whole day downtime to accomplish. Tier 3 tape archives will not be available to our users on that date.

holylfs02 performance issues
  • Вирішено
    Вирішено

    The unrepairable volume on holylfs02 is isolated to two labs and they have been informed of next steps. This issue does not affect other areas on holylfs02, so we are closing this incident.

  • Оновлювати

    Recently we noticed an uptick in bad blocks on a RAID6 disk volume that is part of the entire filesystem. Generally speaking, the operating system will vector these out so no data is written there. During this period, we had to replace a number of drives due to failures; they are part of RAID 6 multi-disk set with dual parity and will rebuild with minimal impact on performance.

    What we believe happened is that, during the rebuild process, bad data was copied to the replacement disks and the filesystem got corrupted. One of the staff ran a read-only, non-destructive repair on the volume in question and noted quite a few errors.

    So far, we have 1) contacted the vendor (who gave us a command to clear additional bad blocks)
    2) NOT run the actual repair command to "fix" the filesystem (which would delete data) 3) contacted the vendor to see if they had any partners that might be able to assist. We are planning to meet with one of those partners early next week, but are not confident they will have a solution. At this point (and depending on how that meeting goes), the next step would be to run the repair, note the extent of loss, and attempt to get the volume remounted.

    Updates to follow when we have more information.

    Note that these shelves are covered under warranty support for another year. We see no need at present to replace the 3PB allocation with new hardware (this is planned to take place Q3-4 FY23)

    Users may experience issues connecting to holylfs02, or slow samba performance.

    This is due to a hardware issue with holylfs02, and we have opened a ticket with the vendor. Updates to follow.

    No ETA.

    Globus has informed us that they will be performing maintenance Saturday June 18th 9am-10am

    ``` During the downtime, the following will be impacted:

    • All services in the Globus ecosystem that use Auth, including Flows, Search, and Timer, will be unavailable.
    • Users will be unable to initiate new transfers. Transfers that are inflight when the downtime begins will resume at the last checkpoint when the services are restored at the end of the maintenance period.
    • Users will not be able to log into applications that rely on Globus Auth, including Globus webapp and command line interface.
    • All third party applications and services that rely on Globus Auth will be impacted, and users will not be able to login/authenticate.
    • Users will be unable to initiate new flow runs. Flow runs that attempt to start a new step during the downtime will fail. We recommend that users check the state of their flow runs after services have resumed. ```

Slurm security patch causing node unavailability
  • Вирішено
    Вирішено

    The scheduler and node states appear to be stable. Thank you for your patience and understanding.

    Please note that the intermittent deadlock issue is still not resolved, but we are actively monitoring that and intervening as necessary until we receive a solution.

  • Моніторинг

    The patch has been deployed and the scheduler restarted. Paused jobs are resuming.

    Any jobs which did not start or were stuck may have been flushed. So please check any pending jobs you might have had.

    We have tested the patch on our test cluster before releasing. We are now proceeding to deploy to the cluster. Thanks for your patience.

    UPDATE: jobs suspended, scheduler down for patching, nodes are updating.

    The Slurm emergency security patch introduced a bug which is causing many of our nodes to be set to 'not responding'. The vendor has already identified the issue and issued another patch.

    We are deploying this patch after testing. Jobs will be paused and the scheduler and cluster will be unavailable while deploying the patch. Watch here for updates.
