[Gluster-users] Geo-replication configuration issue

[Aravinda]

Hi,

Looks like Master Pem keys are not copied to Slave nodes properly, 
Please cleanup /root/.ssh/authorized_keys in Slave nodes and run Geo-rep 
create force again.

gluster volume geo-replication <MASTERVOL> <SLAVEHOST>::<SLAVEVOL> 
create push-pem force

Do you observe any errors related to hook scripts in glusterd log file?

regards
Aravinda
