    The majority of nodes have been physically reseated. Only a handful of these remain and will be dealt with as their jobs clear. Closing this incident.

    அடையாளம் காணப்பட்டது

    Approximately 100 compute nodes in row 7c (holy7cxxxxx) came back up at the wrong clock speed. This is a known issue with some older nodes that can occur after power dip or loss. These nodes will need to be physically reset in the chassis to clear this issue.

    Jobs are running on these nodes so they will need to be drained of jobs before we can do this. As such we are marking the cluster partially degraded.

    However, please note that this is a fraction of the total nodes and should not impact the average user.

    This affects some specific owned partitions:

    doshi-velez - 2 of 2 nodes
    shakhnovich 2 of 3 nodes
    blackhole/blackhole_priority - some % nodes
    hernquist - some % nodes
    pehlevan - some % nodes
    seas_compute - some % nodes
    tambe - some % nodes
    shared - some % nodes
