AFS Service

The AFS (Andrew File System) Service provides networked file storage for CERN users, in particular home directories, work spaces and project spaces.

The AFS Service is based on OpenAFS, an open-source distributed filesystem which provides a client-server architecture for location-independent, scalable, and secure file sharing.

Phaseout

CERN is currently reducing its dependencies on AFS and will eventually phase out this service completely. Please see https://twiki.cern.ch/twiki/bin/view/IT/AfsPhaseout for more details on the phaseout project.

AFS clients for other operating systems are available and functioning, but:

  • they are not included in testing of new versions of the operating systems supported by IT;
  • they are not officially supported in case of problems.
