CellAlias - Maps cell names to aliases in /afs


The CellAlias file is used by the Unix cache manager when it is using Dynamic Root (-dynroot) mode. It creates symbolic links in the dynamic root (/afs) that link an alias for a cell (usually a short name) to the full name for the cell.

The most common use of this configuration file is to allow short names for frequently used cell names. Traditionally, such short names would be created by the local AFS administrator by creating symbolic links in the root.afs volume. Such symlinks do not appear when Dynamic Root is enabled because, with Dynamic Root, the Cache Manager does not mount or look at the root.afs volume. CellAlias is a replacement that allows such short names to be created under the client control.

If you configure a short name mapping such as ir for, the mapping of .ir to for the read/write version of the root.cell volume for that cell will be created automatically. There is no need to list that alias separately. afsd will report an error on startup if the dotted entry is listed separately.

The contents of the CellAlias file should consist of one line of two whitespace-separated columns per alias. The first column is the real name of the cell, and the second column is the alias that should be created.


The following CellAlias file: openafs uncc

results in the following symbolic links:

   /afs/.openafs  ->  /afs/
   /afs/openafs   ->  /afs/
   /afs/.uncc     ->  /afs/
   /afs/uncc      ->  /afs/
