AFS project volumes

Projects and individual users may request AFS space for their work, subject to the following constraints:
  • Project volumes have, at creation, a default size of 5 GB
  • Project volumes may be created with quotas of up to 25 GB. Additional space may be available upon request.
  • Project volumes receive nightly backup, unless users explicitly decline this service

Requesting AFS project space

To request AFS project space, send mail to <help+@cs.cmu.edu> with the following information:
  • Project name
  • Faculty sponsor for the project
  • SCS userIDs of two people who will serve as "project administrators" for the space
  • Name of the initial volume to be created
  • Desired volume size, if greater than the 5 GB default

Managing AFS project space

Tips for project-volume administrators:
  • Past experience indicates that "best practice" involves following consistant volume-naming schemes and, to avoid reserving space that may not be used, extending quotas and creating volumes only as needed
  • Volume names may contain up to 20 alphanumeric characters. Volume names may include a hyphen. Avoid other punctuation and special characters, such as underbar "_". Some popular conventions use <project_name>-N for volumes (e.g. "HQB-hyper-1"), <project_name>-<userid> for a project member's personal space, and <project_name>-src for a source-code repository.
  • Contact the SCS Help Desk, <help+@cs.cmu.edu> or x8-4231, for information on obtaining additional capacity
