    At 8am on Thursday April 30th we will be upgrading from Open OnDemand version 4.0.7 to 4.1.4 on both the Cannon and FASSE clusters.

    This is not expected to impact running jobs.

    This upgrade adds the Jobs->Project Manager menu item and fixes an issue that affected access to the Clusters->Shell Access menu item when using Firefox.

Login and OOD node access restricted due to serious security issue - No ETA
  • Ratkaistu
    UTC
    Ratkaistu

    The cluster has been rebooted and all nodes, including login and OOD, have been patched.

    The scheduler is re-opened and jobs which were preempted/requeued have priority for re-scheduling.

    Some non-standard, lab-owned nodes may still require patching. The owners of these machines may be contacted about this.

    Thank you for your patience. This is a global issue and is being addressed at centers everywhere.

  • Päivitys

    Päivitys

    To mitigate this exploit we will need to restart -all nodes- on the cluster.

    This will begin at 1PM and run until all nodes have restarted (no ETA).

    This will mean any un-finished jobs will be terminated. There is no way to avoid this.

    We will then be validating the fix before re-opening the login. OOD nodes, and scheduler.

    Next steps and updates will be posted here.

    We are developing a plan of attack to mitigate this exploit. Please know that this is a very serious issue and so we are treating it as such. Thank you for your understanding.

    We are currently awaiting further information from the Redhat/Fedora/Rocky community but building a plan in the meantime with the information we have. More details to follow as we can share them.

    If you need to access storage (except scratch and home directories), Globus is still online and available. But again, login nodes and OOD are not available.

    Due to a serious in-the-wild exploit which can compromise Fedora-based Linux distributions including Rocky, which is used on the cluster, we need to restrict access. All login and OOD nodes are shut down until a fix can be put in place. Jobs running on the cluster will continue running.

    No ETA, There is not fix at this time. We will update our status page in the morning once we have more information or a fix to roll out.

    This is a serious exploit and we do not take this measure lightly. Please follow this status page for updates and eventual resolution.

Network issues - Cluster degraded
  • Ratkaistu
    UTC
    Ratkaistu

    This incident has been resolved by draining and rebooting any nodes with stuck mounts.

  • Seurataan
    UTC
    Seurataan

    Mounts to Holyoke Isilon (specifically /n/sw) are broken on numerous nodes across the cluster. We have a check rolling out to find these nodes so we can remediate them individually. Until remediated the cluster will be in a degraded state. Running jobs may randomly die or fail as they hit nodes that have stale mounts.

    It will be risky to run jobs for the next hour and then, after that point, the cluster will have a large number of nodes closed waiting for them to drain so we can reboot them and fix the mounts.

    At this time we are unaware of any holy-isilon problems other than the effect this had on cluster nodes/running jobs. We will update should we identify any data storage concerns.

    The tape library outage is further extended to Wednesday March 4th at 9am awaiting a hardware replacement part due today. Data can still be uploaded to lab collections via Globus, but be mindful of the 10 TB buffer file limit. The outage affects storage and recall from tape.

    NESE Tape Service is still working with IBM technical support at restoring the inventory. The expected downtime is extended until Tuesday March 3rd, 9am.
    Apologies for the inconvenvenience.

  • Tutkitaan

    NESE Tape service will be down or operating with degraded service (no store and recall) Friday from 12 Noon EST until as late as Monday, 2 March at 9 AM.

    SUMMARY OF ISSUE:

    NESE Tape service is currently not able to store or recall files to and from tape due to vendor firmware issues in the IBM TS4500 tape library. The issue is related to the library robotics and cartridge database and we do NOT expect any data loss from this issue.

    The issue is apparently due to an issue with the inventory database related to a recent firmware update. This database can be scrubbed and reconstructed by the library, which will scan the bar code labels on all the cartridges to rebuild the inventory. Association of files in Globus to tapes is handled separately from the tape library and is not affected by the firmware update.
