One other question... Is there a way to set a config variable to turn
off the compression for the rsync?

I was hoping someone could help me debug my geo-replication under
gluster 3.5.2.
I am trying to use geo-replication to create a lagged backup of my
data. What I wanted to do was to turn off the geo-replication (gluster
volume geo-replication homegfs gfsib01bkp.corvidtec.com::homegfs_bkp
stop) during the day, and then turn it back on at midnight to allow
the remote system to sync.
If I stop the geo-replication, delete a file, and then restart the
geo-replication, the deletion never shows up on the slave system.
From the website below, I thought that it would pick up these changes.
Any suggestions for how I can get the changes made while the
geo-replication is stopped to propagate after restart the
geo-replication?
This is a known issue with glusterfs-3.5.2. The problem is xsync can
not handle deletes and renames. So when you restart the geo-rep, the
change detection mechanism falls back to xsync even though the
Changelog was ON, the whole time. So deletes and renames won't be
propagated to slave in 3.5.2
The patch to fix this issue is already submitted and is present in
glusterfs master branch. The fix should be available in glusterfs-3.6
soon.

gluster volume geo-replication <master_volume>
<slave_volume>::<slave_volume> stop [force]
Force option is to be used, when one of the node (or glusterd in one
of the node) is down. Once stopped, the session can be restarted any
time. Note that upon restarting of the session, the change detection
mechanism falls back to xsync mode. This happens even though you have
changelog generating journals, while the geo-rep session is stopped.
