+	<citerefentry><refentrytitle>samba</refentrytitle>
+	<manvolnum>7</manvolnum></citerefentry> suite.</para>
+
+	<para>
+	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 <command>vfs_syncops</command> VFS module
+	provides a way to perform those	operations safely.
+	</para>
+
+	<para>This module is stackable.</para>

+	<title>CONFIGURATION</title>
+
+	<para>
+	Most of the performance loss with the <command>vfs_syncops</command>
+	VFS module is in fsync on close(). You can disable that with
+	<command>syncops:onclose = no</command> that can be set either globally
+	or per share.
+	</para>
+
+	<para>
+	On certain filesystems that only require the last data written to be
+	fsync()'ed, you can disable the metadata synchronization of this module with
+	<command>syncops:onmeta = no</command>. This option can be set either
+	globally or per share.
+	</para>
+
+	<para>
+	The <command>vfs_syncops</command> VFS module can also be disabled
+	completely for a share with <command>syncops:disable = true</command>.
+	</para>
