How best confirm decision on (1) partitions

...

AND (2) their capabilities and use?

(1) Partitions

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 (TBD by 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 (TBD by 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".

Community practice: How develop by group, document and share, and reinforce? Good for new researchers and all current researchers.

How determine and get approval for partition sizes?

Current researhcers

Size of /home

Size of /storage

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 researcherGia asked:

• Desired quota for /home?
• Desired quota for and /storage?
• How much data to transfer to Matrix as soon as it's available, from /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.
