vfs_syncops - Ensure meta data operations are performed synchronously.

This VFS module is part of the samba
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.
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.
Add syncops functionality for [share]:
path = /data/share
vfs objects = syncops
syncops:onclose = no
This man page is correct for version 4.1.0 of the Samba suite.
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.
