+ <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>.
