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  com-
     mit:dthresh value. Secondly, write performance can be improved on some sys-
     tems 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
