+.SH "NAME"
+vfs_commit \- flush dirty data at specified intervals
+.SH "SYNOPSIS"
+.HP \w'\ 'u
+vfs objects = commit
+.SH "DESCRIPTION"
+.PP
+This VFS module is part of the
+\fBsamba\fR(7)
+suite\&.
+.PP
+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\&.
+.PP
+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\&.
+.PP
+This module is stackable\&.
+.SH "OPTIONS"
+.PP
+commit:dthresh = BYTES
+.RS 4
+Synchronize file data each time the specified number of bytes has been written\&.
+.sp
+The following suffixes may be applied to BYTES:
+.RS
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+K
+\- BYTES is a number of kilobytes
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3

+\- BYTES is a number of megabytes
+.RE

+.RS 4
+.ie n \{\

+.el \{\

+G
+\- BYTES is a number of gigabytes
+.RE

+.SH "EXAMPLES"
+.PP
+Synchronize the file data on the [precious] share after every 512 kilobytes (524288 bytes) of data is written:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+ \fI[precious]\fR
+ \m[blue]\fBpath = /data/precious\fR\m[]
+ \m[blue]\fBvfs objects = commit\fR\m[]
+ \m[blue]\fBcommit:dthresh = 512K\fR\m[]
+.fi
+.if n \{\
+.RE
+.\}
+.SH "CAVEATS"
+.PP
+On some systems, the data synchronization performed by
+commit
+may reduce performance\&.
+.SH "VERSION"
+.PP
+This man page is part of version 4\&.19\&.5\-git\&.342\&.57620c4f7eSUSE\-oS16\&.9\-x86_64 of the Samba suite\&.
+.SH "AUTHOR"
+.PP
+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\&.
