Installing OpenAFS/Auristor on Your Device

To increase security and reduce risk, Stanford is sunsetting its WebAFS service that is used to upload and download files to AFS.

To reduce the use of AFS, UIT has taken these actions:

  • UIT no longer automatically provisions new faculty and staff members with AFS user volumes. New faculty or staff who need a personal user volume must submit a Help request.
    • This change does not impact existing AFS directories or the process for adding permissions for new individuals to those existing directories. Your existing space and everything in it remains intact.
    • This change does not impact auto-provisioning of new AFS user volumes for students and postdocs.

    See New Process for Provisioning AFS User Volumes for more information.

  • All user, dept, and group AFS volumes must be renewed annually or they will be locked, archived, and permanently deleted as detailed in the AFS Volume Expiration Policy.
