[Gluster-users] geo replication help

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?

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.
