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 accumulates.

       vfs_commit is useful in two circumstances. First, if you have very precious data, the impact of unex-pected unexpected
       pected  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:


               [precious]
            path = /data/precious
            vfs objects = commit
            commit:dthresh = 512K


CAVEATS
       On some systems, the data synchronization performed by commit may reduce performance.
