I've looked at the docs, and this list of so-called "translators" here:

making sense of how these config files are organized and how/when to
make use of translators.
In particular I have been testing gluster by creating volumes using
the 'gluster' CLI utility, and I am trying to turn on POSIX compliance
or locking in order to support operations on sqlite dbs. It seems this
is done through "translators" like "features/locks", but I'm having
difficulty understanding where to go from here.
Thanks for the post Brandon, I'm doing something very similar. We have
an issue with openvz gluster clients where, due to a vm environment
bug the supplemental groups cannot be properly verified on the servers
(openvz is answering host pid mapping in /proc vs the expected
container pid mapping, so when that broken UID/GID info is sent to the
server for access control, fail).
http://bugs.gluster.com/show_bug.cgi?id=3563
http://bugzilla.openvz.org/show_bug.cgi?id=1992
We are about to attempt a workaround where we manually modify the vol
file on each of the servers to exclude the volume stanza which
contains "type features/access-control", and modify the "type
features/access-control" block to shortcut to the "type storage/posix"
subvolume stanza.
Two major questions are:
a) What is the cksum file and will it cause havoc with our change
b) Is there some way possible to modify one volume file and use a
builtin facility to propagate it to the servers?
Anybody have experience to share?

hi George,
answer for a): cksum file is checksum for something else. It
wont cause any problems for the changes made to volfiles.
answer for b): Since the change is on brick volfile, it is
recommended to stop and start the volume file. It will then load the new
volfile without access-control, let us know if you face any problems.
