biod(1Mnfs)

biod -- NFS daemon

Synopsis

/usr/lib/nfs/biod

Description

The biod command starts the asynchronous block I/O daemons. This command is used on an NFS^® client to buffer read-ahead and write-behind.

Usage

The biod daemons are automatically invoked in run level 3.

biod uses kernel light weight processes (LWPs) to do the asynchronous NFS I/O. The kernel LWPs are created or deleted dynamically, depending on the asynchronous I/O load. The maximum number of LWPs is controlled by the kernel tunables NFS_ASYNC_MAX and NFS_MNT_ASYNC_MAX.

Only a privileged user can start the biod daemons.
