[Gluster-users] Geo-replication slaves are faulty after startup

[Aravinda]

Following command should be run after the Geo-rep create push-pem step

/usr/libexec/glusterfs/set_geo_rep_pem_keys.sh geoaccount gv0 gv0

Please run that command in any one of the slave node and observe the 
Geo-replication status.
