NAME
nfsiod —
SYNOPSIS
nfsiod |
[-n num_servers] |
DESCRIPTION
Thenfsiod utility controls the maximum number of
nfsiod kernel processes which run on an NFS client
machine to service asynchronous I/O requests to its server. Having
nfsiod kernel processes improves performance but is
not required for correct operation.
The option is as follows:
-n- Specify how many processes are permitted to be started.
Without an option, nfsiod displays the
current settings. A client should allow enough number of processes to handle
its maximum level of concurrency, typically four to six.
If nfsiod detects that the running kernel
does not include NFS support, it will attempt to load a kernel module
containing NFS code, using
kldload(2).
If this fails, or no NFS module was available,
nfsiod exits with an error.
EXIT STATUS
Thenfsiod utility exits 0 on success,
and >0 if an error occurs.

Thenfsiod utility first appeared in
4.4BSD.
Starting with FreeBSD 5.0, the utility no longer starts daemons, but only serves as a vfs loader and sysctl(3) wrapper.
