VFS_AIO_FORK(8)		  System Administration tools	       VFS_AIO_FORK(8)

NAME
       vfs_aio_fork - implement async I/O in Samba vfs

SYNOPSIS
       vfs objects = aio_fork

DESCRIPTION
       This VFS module is part of the samba(7) suite.

       The aio_fork VFS module enables async I/O for Samba on platforms where
       the system level Posix AIO interface is insufficient. Posix AIO can
       suffer from severe limitations. For example, on some Linux versions the
       real-time signals that it uses are broken under heavy load. Other
       systems only allow AIO when special kernel modules are loaded or only
       allow a certain system-wide amount of async requests being scheduled.
       Systems based on glibc (most Linux systems) only allow a single
       outstanding request per file descriptor.

       To work around all these limitations, the aio_fork module was written.
       It uses forked helper processes instead of the internal Posix AIO
       interface to create asynchronousity for read and write calls. It has no
       parameters, it will create helper processes when async requests come in
       as needed. Idle helper processes will be removed every 30 seconds.

       This module is stackable.

EXAMPLES
       Straight forward use:

		   [cooldata]
		path = /data/ice
		vfs objects = aio_fork

VERSION
       This man page is correct for version 4.0.0 of the Samba suite.

AUTHOR
       The original Samba software and related utilities were created by
       Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.
