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
