To reset the cache size to the default, do the following:
1. Log in as root on the machine.
2. Use the -reset option with the cm setcachesize command to reset the cache size to the value specified at the last reboot, which is either the value in the CacheInfo file or the value set with the -blocks option of the dfsd command:
# cm setcachesize -reset
The -reset option resets the cache size to the value at the last reboot.
