Jeff,

Thanks for straightening me out. I didn't find it in the source tree. I
happened on documentation here, which seemed to imply this was a current
project as of 2015:

https://github.com/gluster/glusterfs-specs/blob/master/done/GlusterFS%203.5/Disk%20Encryption.md

And those instructions work for Gluster as provide from the Ubuntu PPA at 

https://launchpad.net/~gluster/+archive/ubuntu/glusterfs-3.8

which is of course an "unsupported" version -- if commonly used with Ubuntu.
Curious that it includes an orphan translator.

Best,
Whit
