VPN warning
  • Rešeno
    UTC
    Rešeno

    A VPN certificate for vpn.rc.fas.harvard.edu expired, which led to "Untrusted Server Blocked" messages when attempting to connect. A new certificate has already been added, and you should no longer be getting any errors when connecting to the VPN.

    This incident has been resolved.

Major power event at MGHPCC (Holyoke) data center

    FASSE login and OOD have been returned to service.

    Nadgledanje

    Most resources are once again available. The Cannon (including Kempner), FASSE, and Academic cluster are open for jobs. Please note that FASSE login and OpenOnDemand (OOD) nodes are not yet available. ETA Monday morning.

    Thanks for your patience through this unexpected event.

  • Obaveštenje
    UTC
    Obaveštenje

    Power-up is progressing with, so far, only minor issues which we are addressing according to their impact on returning the cluster to service.

    Expect some remaining effects on less-essential services into tomorrow.

    Please note that login nodes will remain down until we return the cluster and scheduler to service.

  • Obaveštenje
    UTC
    Obaveštenje

    MGHPCC has isolated the cause of the generator failure and will continue to look into the grid failure.

    At this time they will begin re-energizing the facility. Once that is complete and we have confirmed the networking is stable we can begin powering up our resources.

    Please bear with us as this is a long process given the number of systems we maintain and it must be done in stages. Watch this page for updates.

  • Identifikovano
    UTC
    Identifikovano

    With an abundance of caution FASRC and other MGHPCC occupants will not attempt to rush to restoration but will wait until the facility has restored primary power and confirmed stable operation before attempting to resume normal operations.

    As such, we expect to begin restoring FASRC services tomorrow (Sunday). Since all Holyoke services and resources are down, this is a lengthy process similar to the startup process after the annual power-down.

    Updates will be posted here. Please consider subscribing to our status page (see 'Get Updates' up top).

    There has been a major power event at MGHPCC, our Holyoke data center.
    We are awaiting further details

    This likely affects all holyoke resources including the cluster and storage housed in holyoke.

    More details as we learn them.

Slurm - critical security patch

    SchedMD (the maintainers of Slurm) have discovered a critical security flaw in Slurm. Due to the nature and severity of the issue, we will be immediately applying this patch.

    Cannon and FASSE schedulers will remain down for the duration of the patching. All running jobs will be paused, and new jobs will not be accepted until the scheduler is back up.

    ETA is expected to be approximately one hour.

    The issue with holylabs (and potentially other lustre filesystems) has recurred. This may have effects on jobs and any process using this and potentially other lustre filesystems.

    No ETA at this time.

  • Rešeno

    We have restored access to holylabs and the cluster/jobs are no longer paused.

    We have identified a root cause which we will be working to remediate to prevent this issue in future.

    The holylabs filesystem is currently down due to high load.

    OOD, software, and modules are all functional but if your workflow uses holylabs for storage, scripts, or jobs it may hang or fail. Our engineers are investigating this issue further.

    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.

    Please note the extended timeframe.
    See tasks section below for explanation.

    NOTICES

    • CentOS 7 Support EOL: We will be dropping support for CentOS 7 support in September. If your machine or VM is CentOS 7 and connects with Slurm please contact FASRC to discuss options.

    • Test Partition Changes: We are changing test partitions based on changing needs and increasing max time to 12hrs instead of 8 hrs. A reminder that this partition is not for running jobs.

    MAINTENANCE TASKS

    • holyscratch01 Disk Shelf Replacement  All Jobs Will Be Paused
      -- Audience : All cluster and scratch users - Cannon and FASSE
      -- Impact:  Hardware issues with holyscratch01 necessitate the replacement of one of the disk shelves. As a result all jobs and scratch will need to be paused for the duration.
      -- ETA: This swap is expected to take 3-4 hours, but pausing the cluster, vendor interactions, and allowing a margin for over-run requires that we extend maintenance by 2 hours  (7am-1pm)

    • Login node and OOD/VDI reboots
      -- Audience: Anyone logged into a a login node or VDI/OOD node
      -- Impact: Login and VDI/OOD nodes will rebooted during this maintenance window
