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
