Ceph instability - Affects Boston VMs (Virtual Machines) and Tier2 Ceph shares
  • 解決済み
    解決済み

    The Ceph instability has been resolved. Ceph Tier2 shares, VDI, and VMs should be back to their normal state.

    If your VM, /net/fs-[labname] share, or VDI session is still impacted, please contact rchelp@rc.fas.harvard.edu

  • 原因判明済み

    The infrastructure behind Tier2 Ceph shares and VMs is unstable.
    This also affects VDI/OOD which relies on virtual machines.

    /net/fs-[labname] shares, new OOD/VDI sessions, and VMs are affected and may will be inaccessible until this is resolved.

    There has been a loss of street power at MGHPCC, our Holyoke data center due to the windstorm. We are awaiting further details.

    This likely affects most of the Cannon/Kempner compute cluster, and all of the FASSE compute cluster.

    More details as we learn them.

    SchedMD has issued a patch for a critical security vulnerability. It is imperative that we apply this patch ASAP. This will require a pause of the cluster for roughly 30-60 minutes at around 11am, after which jobs and the scheduler will continue normal operation.

    A side effect of this is that we will move up to version 23.02.7 with the patch which will fix the IntelMPI and PMI2 issues some users have experienced.

    Thanks for your understanding and patience.

Partial Cannon outage

    Cooling and power have been restored to the affected racks. The compute nodes have been resumed in Slurm and are now accepting jobs again.

    This incident has been resolved.

  • 原因判明済み
    原因判明済み

    We have identified the partitions that are impacted due to loss of cooling in holy7c[02-12] compute nodes. Some of these partitions are fully down, others are partially down.

    The Holyoke MGHPCC data center is working to restore cooling, and FASRC staff are onsite to assist. No ETA.

    Compute nodes in holy7c[02-12] have experienced a power loss and are currently down. GPUs are not impacted at this time.

    The 'shared' partition is significantly impacted. Other public partitions and lab-owned partitions may be down or running at reduced capacity. Jobs are still being accepted/running, but may need to wait longer in the queue due to fewer resources being available.

    We are in contact with the Holyoke MGHPCC data center to investigate further. Updates to come. No ETA at this time.

Major power event at MGHPCC (Holyoke) data center

    FASSE login and OOD have been returned to service.

  • 監視中
    監視中

    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.

  • 更新
    更新

    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.

  • 更新
    更新

    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.

  • 原因判明済み
    原因判明済み

    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.

  • 調査中
    調査中

    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.
