This VFS module is part of the samba
The vfs_commit VFS module keeps track of the amount of data written to a file
and synchronizes it to disk when a specified amount accumulates.
vfs_commit is useful in two circumstances. First, if you have very precious
data, the impact of unexpected power loss can be minimized by a small
commit:dthresh value. Secondly, write performance can be improved on some
systems by flushing file data early and at regular intervals.
This module is stackable.
commit:dthresh = BYTES
Synchronize file data each time the specified
number of bytes has been written.
The following suffixes may be applied to BYTES:
•K - BYTES is a number of
•M - BYTES is a number of
•G - BYTES is a number of
Synchronize the file data on the [precious] share after every 512 kilobytes
(524288 bytes) of data is written:
path = /data/precious
vfs objects = commit
commit:dthresh = 512K
On some systems, the data synchronization performed by commit may reduce

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.
