Changing the number of biod threads and nfsd daemons

The chnfs command can be used to change the maximum number of biod or nfsd daemons that will run on a system.

For example, to set the number of maximum nfsd daemons to 1000, run the following command:

chnfs -n 1000

Note: This command will stop the currently running daemons, update the SRC configuration information, and then restart the daemons. As a result, NFS service will be temporarily unavailable.

The maximum number of biod threads can be specified on a per mount basis using the biods=n mount option.

Note: If the number of nfsd daemons is not sufficient to serve the client, a nonidempotent operation error is returned to the client. For example, if the client removes a directory, an ENOENT error is returned even though the directory on the server is removed.
