cacheinfo(5)

NAME

   cacheinfo - Defines configuration parameters for the Cache Manager

DESCRIPTION

   The cacheinfo file defines configuration parameters for the Cache
   Manager, which reads the file as it initializes.

   The file contains a single line of ASCII text and must reside in the
   /etc/openafs directory. Use a text editor to create it during initial
   configuration of the client machine; the required format is as follows:

      <mount>:<cache>:<size>

   where

   <mount>
       Names the local disk directory at which the Cache Manager mounts
       the AFS namespace. It must exist before the afsd program runs. The
       conventional value is /afs. Using any other value prevents
       traversal of pathnames that begin with /afs (such as pathnames to
       files in foreign cells that do use the conventional name).  The
       -mountdir argument to the afsd command overrides this value.

   <cache>
       Names the local disk directory to use as a cache. It must exist
       before the afsd program runs. The standard value is
       /usr/vice/cache, but it is acceptable to substitute a directory on
       a partition with more available space. Although the Cache Manager
       ignores this field when configuring a memory cache, a value must
       always appear in it. The -cachedir argument to the afsd command
       overrides this value.

   <size>
       Specifies the cache size as a number of 1-kilobyte blocks. Larger
       caches generally yield better performance, but a disk cache must
       not exceed 90% of the space available on the cache partition (85%
       for AIX systems), and a memory cache must use no more than 25% of
       available machine memory.

       The -blocks argument to the afsd command overrides this value. To
       reset cache size without rebooting on a machine that uses disk
       caching, use the fs setcachesize command. To display the current
       size of a disk or memory cache between reboots, use the fs
       getcacheparms command.

EXAMPLES

   The following example cacheinfo file mounts the AFS namespace at /afs,
   establishes a disk cache in the /usr/vice/cache directory, and defines
   cache size as 50,000 1-kilobyte blocks.

      /afs:/usr/vice/cache:50000
