NAME
vfs_commit - flush dirty data at specified intervalsSYNOPSIS
- 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.
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:
-
[precious] m[blue]path = /data/preciousm[] m[blue]vfs objects = commitm[] m[blue]commit:dthresh = 512Km[]
CAVEATS
On some systems, the data synchronization performed by commit may reduce performance.
