How best confirm decision on (1) partitions AND (2) their capabilities and use?

Current idea:

  • /home (3TB total)
    • Can be seen by compute nodes. Data stored on compute nodes until work is done, then moved to /home.
    • Data on /home removed when not actively needed for their cluster work. Can move the data to /storage, for safe-keeping and convenient access.
    • Data is backed up via EZ-Backup.
    • A new user gets 50GB, by default.
    • The process to request more space is through group designate.
  • /storage (8TB total)
    • Can NOT be seen by compute nodes.
    • This is to store data related only to Scheraga research. No personal files.
    • Data is backed up via EZ-Backup.
    • The process to request more space is through group designate.
  • TBD (1TB)
    • To be used for either expanding /home or /storage at a later date (when we know which needs more space sooner than the other).
  • /notbackedup] (4TB)
    • For when a researcher needs more temporary space than an individual compute node can provide.
    • Researcher must move data off as soon as they are done with it.
    • This data is NOT BACKED UP. Use only temporarily, and only when a researcher needs "surge" space.
    • No quotas. Thus, potential for researchers to "step on each other".

ChemIT must be given 2 quotas for each user.

For each current researcher, a quota must separately be specified for their:

  • /home
  • /storage

ChemIT has provided Gia the current use and single quota for each researcher.

  • This quota is a combination of both /home-type use and /storage-type use.

Gia has asked every researcher:

  • Desired quota for /home?
  • Desired quota for/storage?
  • How much data to transfer to Matrix's /storage when it is made available (from their local hard drives, etc.)?

Many researchers have not replied to Gia.

  • ChemIT will thus create a report to Gia with when they last logged in.

How get approval for process to copy researchers' files from old Matrix to the new Matrix?

Idea:

  • Create empty /home directories for each user.
  • ChemIT copies all a user's data in old Matrix to the new Matrix's "storage" partition. Each researcher selectively moves what is required to their new Matrix home directory.

Group documentation

Community standard of practice

Oliver to move whiteboard outline to here, as a favor

To do's:

Group finds place to host.

  • Example: CU's CIT Confluence (such as this page!)

Group identifies owner who can develop  these agreements.
