Hi,
When S3 is added to master volume from new node, the following cmd should
be run to generate and distribute ssh keys
1. Generate ssh keys from new node
#gluster system:: execute gsec_create
2. Push those ssh keys of new node to slave
#gluster vol geo-rep <mastervol> <slavehost>::<slavevol> create
push-pem force
3. Stop and start geo-rep
But note that while removing brick and adding a brick, you should make sure
the data from the brick being removed is synced
to slave.
Thanks,
Kotresh HR
