vfs_commit
flush dirty data at specified intervals
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:
K - BYTES is a number of kilobytes
M - BYTES is a number of megabytes
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:
/data/precious
commit
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.
