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

    The Ceph instability has been resolved. Caeph 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

    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.

    Thanks for your patience.

holylabs inaccessible - cluster paused
  • Решено
    Решено

    We have reverted the routing systems involved in causing this issue to their previous version/state. We will continue to investigate why this issue occurred and what will allow us to upgrade these systems at a later date.

  • Изучается
    Изучается

    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.

  • Решено
    Решено

    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.

  • Определено
    Определено

    The scheduler and all jobs have been paused in order to reduce the load on holylabs.

    We are continuing to work on a fix for this incident.

  • Изучается
    Изучается

    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 performance
  • Решено
    Решено

    This incident has been resolved.

  • Изучается
    Изучается

    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.

FASRC Monthly maintenance August 7, 2023 7am-1pm *NOTE EXTENDED TIME*
  • Завершено

    Завершено
    августа 07, 2023 в 13:42

    Due to a vendor error we were unable to complete holyscratch01 disk shelf replacement. We will work with the vendor to reschedule.

    All other maintenance tasks have completed.

  • В ходе выполнения

    August maintenance will run August 7, 2023 from 7am-1pm.

    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  

    • Scratch cleanup ( https://docs.rc.fas.harvard.edu/kb/policy-scratch/ )
      -- Audience: Cluster users
      -- Impact: Files older than 90 days will be removed.

    Numerous nodes are in a bad state (marked 'drng', but not those marked 'drain'). We are aware and are working to re-open these nodes as quickly as possible.

    This includes but is not limited to nodes in: argelles-delgado, kozinsky, seas_compute, kempner, and other partitions.

Software modules not available
  • Решено

    The proscribed driver update did not fix this issue.

    We are working with Nvidia to find a fix. As a stop-gap nodes which get stuck/flagged will be marked in Slurm for reboot and rebooted once empty of jobs.

    If a A100 GPU host your lab owns is stuck in a bad state, please let us know and we will mark and reboot it.

  • Определено

    An NVIDIA bug may be causing failures in A100 GPUs. nvidia-smi command is slow, or outputs "ERR!" or "No GPUs are found".

    Jobs on affected nodes may fail.

    We are investigating this issue.
