Hi,<br>

Can you check /root/.ssh/authorized_keys (in master host) ? <br>
</blockquote>
<br>
Sorry..typo , this is in slave host (ks4 in your case)<br>
<br>
<blockquote cite="mid:57959CB2.4080701@redhat.com" type="cite"> It
should contain only entries starting with "command=" .<br>
If there is any duplicate entry without "command=" , delete the
same.<br>
and check the geo-rep status again.<br>
<br>

This is to confirm ssh connection between master and slave:<br>
When do run the following, you should get gsynd prompt(from master
to slave).<br>
<br>
ssh -i /var/lib/glusterd/geo-replication/secret.pem root@slave<br>
<br>

Slave is ks4 in your case.<br>
