NAME
vfs_commit - flush dirty data at specified intervals
SYNOPSIS
vfs objects = commit
DESCRIPTION
This VFS module is part of the samba(7) suite.
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.
OPTIONS
commit:dthresh = BYTES
Synchronize file data each time the specified number of bytes has
been written.
The following suffixes may be applied to BYTES:
o K - BYTES is a number of kilobytes
o M - BYTES is a number of megabytes
o G - BYTES is a number of gigabytes
EXAMPLES
Synchronize the file data on the [precious] share after every 512
kilobytes (524288 bytes) of data is written:
[precious]
path = /data/precious
vfs objects = commit
commit:dthresh = 512K
CAVEATS
On some systems, the data synchronization performed by commit may
reduce performance.
VERSION
This man page is part of version 4.13.17 of the Samba suite.
