ca_size(1) CLIX ca_size(1)
NAME
ca_size - Calculates minimum disk and memory size needed for Cache File
System (CAFS)
SYNOPSIS
/etc/ca_size inodes partitions jukeboxes daemons maxsubfs
DESCRIPTION
The CAFS copies files from an optical disk to a magnetic partition
exclusively reserved for CAFS. To create a partition large enough for
cache, it is necessary to know the number of jukeboxes (jukeboxes), cache
daemons (daemons), cache partitions (partitions), the maximum number of
subordinate file systems (maxsubfs), and the total number of subordinate
file system inodes (inodes).
The ca_size command returns minimum disk and memory sizes to meet your
system's CAFS requirements. These are minimum sizes, but it is
recommended to use more than the minimum disk and memory sizes. A larger
cache partition will improve performance and help prevent thrashing of the
cache.
EXAMPLES
To calculate the minimum disk and memory size for CAFS using 31,833
inodes, 2 partitions, 1 jukebox, 5 cache daemons, and up to 200
subordinate file systems, key in the following command line:
ca_size 31833 2 1 5 200
EXIT VALUES
The ca_size command exits with a value of 0 if successful. If
unsuccessful, it exits with a nonzero value.
