cacheinfo - Defines configuration parameters for the Cache Manager
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
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
- 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
- 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
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
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.
