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
