This looks like the hang because stderr buffer filled up with errors
messages and no one reading it.
I think this issue is fixed in latest releases. As a workaround, you can do
following and check if it works.

 rsync version should be > 3.1.0

gluster volume geo-replication <MASTERVOL> <SLAVEHOST>::<SLAVEVOL> config
rsync-options "--ignore-missing-args"
