    /dfs4/bsg

    /dfs5/bio

    /dfs4/rao_col

  • Daily syncs are currently running; a final sync will be run once the systems are quiet.

  • Most user directories on affected filesystems update quickly; however, a few accounts are taking 2-3 days to pick-up daily changes. We’ll reach out to those users individually to warn them that their files will not be accessible for a few days.

  1. All existing logins will be terminated.

  2. You will NOT have access to HPC3 during the planned downtime.
