nfsiod8

Usage

Overview

nfsiod is deprecated. See nfs.conf(5) for NFS configuration info.

nfsiod controls the maximum number of asynchronous I/O threads used for NFS mounts. Historically, it has consisted of a daemon that never exits. However, asynchronous I/O requests are now serviced by threads launched on demand in the kernel and the nfsiod command simply sets the configuration limit.

Having asynchronous I/O threads improves performance but is not required for correct operation.

The options are as follows:

-n

Specify maximum number of asynchronous I/O threads to be used.

If no maximum is specified, nfsiod displays the current value. The default value is 16. A client should allow enough threads to handle its maximum level of concurrency.

The nfsiod utility exits 0 on success, and >0 if an error occurs.
