Hi Kotresh,
Thank you. Unfortunately, it doesn't seem to have made much difference,
with rsync still hammering the CPU.
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

Subject: 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
