Network issues - Cluster degraded
  • Rezolvat
    UTC
    Rezolvat

    This incident has been resolved by draining and rebooting any nodes with stuck mounts.

  • În curs de monitorizare
    UTC
    În curs de monitorizare

    Mounts to Holyoke Isilon (specifically /n/sw) are broken on numerous nodes across the cluster. We have a check rolling out to find these nodes so we can remediate them individually. Until remediated the cluster will be in a degraded state. Running jobs may randomly die or fail as they hit nodes that have stale mounts.

    It will be risky to run jobs for the next hour and then, after that point, the cluster will have a large number of nodes closed waiting for them to drain so we can reboot them and fix the mounts.

    At this time we are unaware of any holy-isilon problems other than the effect this had on cluster nodes/running jobs. We will update should we identify any data storage concerns.

    The tape library outage is further extended to Wednesday March 4th at 9am awaiting a hardware replacement part due today. Data can still be uploaded to lab collections via Globus, but be mindful of the 10 TB buffer file limit. The outage affects storage and recall from tape.

    NESE Tape Service is still working with IBM technical support at restoring the inventory. The expected downtime is extended until Tuesday March 3rd, 9am.
    Apologies for the inconvenvenience.

    În curs de investigare

    NESE Tape service will be down or operating with degraded service (no store and recall) Friday from 12 Noon EST until as late as Monday, 2 March at 9 AM.

    SUMMARY OF ISSUE:

    NESE Tape service is currently not able to store or recall files to and from tape due to vendor firmware issues in the IBM TS4500 tape library. The issue is related to the library robotics and cartridge database and we do NOT expect any data loss from this issue.

    The issue is apparently due to an issue with the inventory database related to a recent firmware update. This database can be scrubbed and reconstructed by the library, which will scan the bar code labels on all the cartridges to rebuild the inventory. Association of files in Globus to tapes is handled separately from the tape library and is not affected by the firmware update.

    MAINTENANCE TASKS

    Cannon cluster will be paused during this maintenance?: YES
    FASSE cluster will be paused during this maintenance?:YES

    • Slurm upgrade to 25.11.1

      • Audience: All cluster users (Cannon and FASSE)

      • Impact: Jobs will be paused during maintenance

    • In conjunction with SEAS we will modify seas_gpu and seas_compute time limits 

      • Audience: SEAS users

      • Impact:
        seas_gpu: will be set to 2 days maximum
        seas_compute: will be set to 3 days maximum

        Existing pending jobs longer than these limits will be set to 2 day and 3 day run times depending on partition.

    • Job Age Priority Weight Change

      • Audience: Cluster users

      • Impact: We will be adjusting the weight applied to the priority earned by jobs by virtue of their age. Currently job priority is made up of two factors, Fairshare and Job Age. The Job Age factor is currently set such that jobs gain priority over 3 days with a maximum priority equivalent to jobs with Fairshare of 0.5. This keeps low fairshare jobs from languishing at the bottom of the queue. With the current settings though, users with low fairshare can gain significant advantage over users with higher relative fairshare. To remedy this we will be adjusting the Job Age weight to cap out at an equivalent Fairshare of 0.1. This will still allow jobs with 0 fairshare to gain priority and thus not languish while letting fairshare govern a wider range of higher priority jobs.

    • Login node reboots

      • Audience; All login node users

      • Impact: Login nodes will reboot during the maintenance window

    • Open OnDemand (OOD) node reboots

      • Audienc:; All OOD users

      • Impact: OOD nodes will reboot during the maintenance window

    • Netscratch retention will run

      • Audience: All cluster netscratch users

      • Impact: Files older than 90 days will be removed. Please note that retention cleanup can and does run at any time, not just during the maintenance window.
