vfs_commit
VFS_COMMIT(8) VFS_COMMIT(8)
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 accumu-
lates.
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 inter-
vals.
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 correct for version 3.0.25 of the Samba suite.
AUTHOR
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.
