[Gluster-users] Geo-replication configuration issue

Mon Jul 25 04:59:30 UTC 2016

Hi,

1.
Can you check   /root/.ssh/authorized_keys (in master host) ?
It should contain only entries starting with "command=" .
If there is any duplicate entry without "command=" , delete the same.
and check the geo-rep status again.

2.
This is to confirm ssh connection between master and slave:
When do run the following, you should get gsynd prompt(from master to 
slave).

ssh -i /var/lib/glusterd/geo-replication/secret.pem root at slave

3.
check your firewall settings

Thanks,
Saravana
