VFS_COMMIT(8)		  System Administration	tools		 VFS_COMMIT(8)

NAME
       vfs_commit - flush dirty	data at	specified intervals

SYNOPSIS

       vfs objects = commit

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

       The vfs_commit VFS module keeps track of	the amount of data written to
       a file and synchronizes it to disk when a specified amount accumulates.

       vfs_commit is useful in two circumstances. First, if you	have very
       precious	data, the impact of unexpected power loss can be minimized by
       a small commit:dthresh value. Secondly, write performance can be
       improved	on some	systems	by flushing file data early and	at regular
       intervals.

       This module is stackable.

OPTIONS
       commit:dthresh =	BYTES
	   Synchronize file data each time the specified number	of bytes has
	   been	written.

	   The following suffixes may be applied to BYTES:

		     K	- BYTES	is a number of kilobytes

		     M	- BYTES	is a number of megabytes

		     G	- BYTES	is a number of gigabytes

EXAMPLES
       Synchronize the file data on the	[precious] share after every 512
       kilobytes (524288 bytes)	of data	is written:

		   [precious]
		path = /data/precious
		vfs objects = commit
		commit:dthresh = 512K

CAVEATS
       On some systems,	the data synchronization performed by commit may
       reduce performance.

VERSION
       This man	page is	part of	version	4.20.7 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.
