AFS(5) AFS File Reference AFS(5)


afs - Introduction to AFS files


A number of files must reside on the local disk of AFS server and client machines. They belong to the following general categories:

  • Configuration files define configuration parameters for specific server and kernel processes such as the Backup System Tape Coordinator or the Cache Manager.
  • Administrative files list information used in administration of server machines, such as a list of privileged users or server encryption keys.
  • Cache-related files contain cached data or information about cached data, on client machines.
  • Log files contain tracing messages about the operation of a specific process.
  • Database files contain database records used to administer the AFS cell.
  • Controller files control the behavior of a process.
  • Volume header files represent AFS volumes on server partitions.

For a description of the format and contents of each file, see its reference page.

Note for Windows users: Some files described in this document possibly do not exist on machines that run a Windows operating system. Also, Windows uses a backslash ("\") rather than a forward slash ("/") to separate the elements in a pathname.
