Consistency Checking on Demand

Consistency checks can be performed only when you explicitly request checks for file systems that are mounted by using the -o demandconst option. If you mount a file system in a cache with this option, then use the cfsadmin command with the -s option to request a consistency check. By default, consistency checking is performed file by file as the files are accessed. If no files are accessed, no checks are performed. Using the -o demandconst option avoids the situation where the network is flooded with consistency checks.
