Gluster users - Nov 2014 - Disable rsync compression for georeplication

Using Gluster 3.4.2, we have a situation where georeplication is causing 
the CPU on the master to be hammered, while the bandwidth is having a 
holiday. I'd therefore like to disable the rsync compression for 
georeplication.

In a response to David F. Robinson asking the same question back in 
August, Vishwanath Bhat wrote:

Finding no way to negate the --compress option used in georeplication I 
thought that perhaps I could get part way there by simply winding down 
the compression level using "gluster volume geo-replication <MASTER> 
<SLAVE> config rsync-options '--compress-level=0' " (Yes, I
did use real
entries for <MASTER> and <SLAVE>.)

The return from that command was "unrecognized option 
--compress-level=0". I tried a few other numbers and got the same 
negative results.

Can someone please advise how to disable rsync compression for 
georeplication? Thanks.

regards,
John

Hi John,

There seems to a bug in cli command line parsing which is not allowing 
options prefixed with double hyphen apart from few. As a workaround to fix
this for now, do following steps.

1. Stop geo-replication session.
2. Add the following at the end of the file
"/var/lib/glusterd/geo-replication/gsyncd.conf" in all master nodes.
   rsync_options = --compress-level=0
3. Start geo-replication session.

Thanks and Regards,
Kotresh H R
