Ceph instability - Affects Boston VMs (Virtual Machines) and Tier2 Ceph shares
  • Resolved
    Resolved

    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

  • Identified

    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.
