NAME
       vfscommit - flush dirty data at specified intervals

SYNOPSIS
       vfs objects = commit

DESCRIPTION
       This VFS module is part of the ssaammbbaa(7) suite.

       The  vfscommit VFS module keeps track of the amount of data written to
       a file and synchronizes it to disk when a specified amount accumulates.

       vfscommit is useful in two circumstances. First, if you have very pre-
       cious 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.

OOPPTTIIOONNSS
       commit:dthresh = BYTES
          Synchronize file data each time the specified number  of  bytes  has
          been written.

          The following suffixes may be applied to BYTES:

             +o  K - BYTES is a number of kilobytes

             +o  M - BYTES is a number of megabytes

             +o  G - BYTES is a number of gigabytes

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


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


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