    FASRC monthly maintenance will take place on April 6th 2026. Our maintenance tasks should be completed between 9am-1pm.

    NOTICES:

    MAINTENANCE TASKS

    Cannon cluster will be paused during this maintenance?: NO
    FASSE cluster will be paused during this maintenance?: NO

    • two-factor.rc.fas.harvard.edu OpenAuth cut-over to new server

      • Audience: New accounts or anyone requesting an OpenAuth token

      • Impact: two-factor will be unavailable while moving to a new server

    • RStudio Server (Open OnDemand)

      • Audience: RStudio Server users on Cannon and FASSE

      • Impact: We will be decommissioning some versions of RStudio Server so we can properly maintain all production versions. Versions to be decommissioned:

        • R 4.1.3 (Bioconductor 3.14, RStudio 2022.02.0)

        • R 4.1.0 (Bioconductor 3.13, RStudio 1.4.1717)

        • R 4.0.3 (Bioconductor 3.12, Rstudio 1.3.1093)

        • R 4.0.0 (Bioconductor 3.11, Rstudio 1.3.1093)

      • If you use one of these versions, we recommend replacing it with the most recent version, R 4.4.2 (Bioconductor 3.20, RStudio 2024.12.0). You must reinstall previously installed libraries.

    • Domain controller replacement

      • Audience: Internal

      • Impact: End users should not see any impact

    • OOD/Open OnDemand reboots

      • Audience: All OOD users, reboot of the head nodes

      • Impact: Running sessions will not be affected

    • Login node reboots

      • Audience; All login node users

      • Impact: Login nodes will reboot during the maintenance window

    • Netscratch 90-day retention cleanup

      • Audience; All netscratch users

      • Impact: Files older than 90 days will be removed per our scratch policy. Please note that this cleanup can happen at any time, not just during maintenance.

Network issues - Cluster degraded
  • Resolved
    Resolved

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

  • Monitoring
    Monitoring

    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.

  • Investigating
    Investigating

    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.
