  • GeplantAugust 22, 2022 um 10:00UTC

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

    We have been informed that they will be performing a significant upgrade of their Spectrum Scale archive system starting August 15th. This is a multi-day upgrade and will take approximately 3 days (potential for longer). Tier 3 tape allocations will be unavailable during this upgrade.

    NESE has informed us that this maintenance will be deferred to next week (9/22/22).

holyscratch01 issues
GelöstBeeinträchtigte Leistung23 Stunden 5 Minuten
  • GelöstUTC

    The offending jobs have been cancelled. Holyscratch01 should be usable again now.

  • AnalyseUTC

    holyscratch01 is in a degraded state currently. A group of improperly architected jobs are hammering the filesystem which is impeding access for other users. We are in the process of identifying and stopping these jobs.

    Until then, we recommend starting an interactive session and working from there as those will have the lowest impact. However, performance will still be slow until we are able to stop the problematic jobs.

holylfs02 performance issues
Gelöst815 Stunden 14 Minuten
  • GelöstUTC

    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.

  • UpdateUTC

    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)

  • IdentifizierungUTC

    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. ```
CVMFS not available from login nodes
Gelöst311 Stunden 44 Minuten
  • GelöstUTC

    This issue is currently not fixable on the login nodes. CVMFS can still be used on compute, but not login nodes. We are in contact with OSG and if there is a workaround later we will implement it. As a result, this incident is now closed.

  • AnalyseUTC

    CVMFS is available from compute nodes, but not from login nodes. This will only impact users who need this filesystem (OpenScienceGrid).

    We will investigate this incident further next week.
