Release Announcements
---------------------

This is the latest stable release of the Samba 4.12 release series.

Major enhancements include:

  o BUG 14537: ctdb-common: Avoid aliasing errors during code optimization.
  o BUG 14486: vfs_glusterfs: Avoid data corruption with the write-behind
               translator.


=======
Details
=======

The GlusterFS write-behind performance translator, when used with Samba, could
be a source of data corruption. The translator, while processing a write call,
immediately returns success but continues writing the data to the server in the
background. This can cause data corruption when two clients relying on Samba to
provide data consistency are operating on the same file.

The write-behind translator is enabled by default on GlusterFS.
The vfs_glusterfs plugin will check for the presence of the translator and
refuse to connect if detected. Please disable the write-behind translator for
the GlusterFS volume to allow the plugin to connect to the volume.
