Symlinking gluster to /usr/bin/ seems to have resolved the path issue.
Thanks for the tip there.
Now there's a different error throw in the geo-rep/ssh...log:

I also get a bunch of these errors but have been assuming that they are
being thrown because geo-replication hasn't started successfully yet. There
is one for each brick:

Do I have a config file error somewhere that I need to track down? This
volume *was* upgraded from 3.4.2 a few weeks ago.
