VFS_SYNCOPS(8)		  System Administration	tools		VFS_SYNCOPS(8)

NAME
       vfs_syncops - Ensure meta data operations are performed synchronously.

SYNOPSIS

       vfs objects = syncops

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

       Some filesystems	(even some journaled filesystems) require that a
       fsync() be performed on many meta data operations to ensure that	the
       operation is guaranteed to remain in the	filesystem after a power
       failure.	This is	particularly important for some	cluster	filesystems
       which are participating in a node failover system with clustered	Samba.
       On those	filesystems the	vfs_syncops VFS	module provides	a way to
       perform those operations	safely.

       This module is stackable.

CONFIGURATION
       Most of the performance loss with the vfs_syncops VFS module is in
       fsync on	close(). You can disable that with syncops:onclose = no	that
       can be set either globally or per share.

       On certain filesystems that only	require	the last data written to be
       fsync()'ed, you can disable the metadata	synchronization	of this	module
       with syncops:onmeta = no. This option can be set	either globally	or per
       share.

       The vfs_syncops VFS module can also be disabled completely for a	share
       with syncops:disable = true.

EXAMPLES
       Add syncops functionality for [share]:

		   [share]
		path = /data/share
		vfs objects = syncops
		syncops:onclose	= no

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.
