       vfs_commit - flush dirty data at specified intervals


       vfs objects = commit


       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.


       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


       Synchronize the file data on the [precious] share after every 512 kilobytes (524288 bytes)
       of data is written:

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


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


       This man page is part of version 4.16.4-Ubuntu of the Samba suite.

       is now developed by the Samba Team as an Open Source project similar to the way the Linux
       kernel is developed.
