       vfs_syncops - Ensure meta data operations are performed synchronously.


       vfs objects = syncops


       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

       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.
