Yes, GlusterFS does aggressively try to maintain consistency of volfiles with
the current configuration.  Having probably written more third-party or
experimental translators than anyone I agree that this is incredibly
inconvenient, but it probably still avoids more problems than it creates.
There *is* a hook to add custom translators, so that they'll get re-added any
time the volfile is regenerated.  Details here:


If you want to write such a filter in Python, there's a library called
volfilter.py that can parse/manipulate volfiles.  I've used it for several
different projects, and a version is included in the GlusterFS source tree.

With respect to more general support for custom translators via the CLI and so
on, I suggest following this feature proposal:


Even better, chip in with some suggestions of what you think the interface
should look like, since that's not entirely clear yet.  Thanks!
