AFS cells

AFS is organized into administrative units called cells. Each cell has its own accounts, file-space organization, and policies. Some of the AFS cells at CMU are:

cs.cmu.edu
Administered by SCS Facilities.
andrew.cmu.edu
Administered by CMU Computing Services.
ece.cmu.edu
Administered by ECE Facilities.
Hosts running AFS will belong to a particular cell. You can run the command:
   fs wscell
to see which cell the host you are on belongs to.

By convention, on hosts running AFS, files for each cell are located under the directory /afs/<cellname>. For example, files in the cs.cmu.edu cell are located under /afs/cs.cmu.edu/. On hosts running the SCS Facilities environment, you can abbreviate the cellname and just use the first component of the name for AFS cells at CMU. For example: /afs/cs/ or /afs/andrew/.
