AFS Project Directory

AFS Project Directory

If it’s not a research group and it’s not an individual user, it must be a project! That’s the basic distinction. Project directories live in /afs/csail.mit.edu/proj/PROJECTNAME and are otherwise similar to group directories except for the following differences:

• Project directories have smaller default quotas (20 GB or smaller).
• Projects’ corresponding protection groups are self-administered and do not have parallel -admin groups.
• Project directories use the http://projects.csail.mit.edu/ Web server.

Many project directories are used primarily for Web hosting for lab-wide activities that are run by different people from year to year (such as http://projects.csail.mit.edu/gsb/) Some of them are used for infrastructure functions like the courses.csail.mit.edu virtual Web server (and indeed the Web server configuration itself).

The AFS volume for a project is named proj.PROJECTNAME. As with other CSAIL AFS volumes, a nightly snapshot is taken and is mounted at .snapshot in the top level of the project volume.
