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
/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
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.
