Manual Reference Pages - CACHEINFO (5)
cacheinfo - Defines configuration parameters for the Cache Manager
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
/usr/local/etc/openafs directory. Use a text editor to create it during initial
configuration of the client machine; the required format is as follows:
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.
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.
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.
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.
