Hi everyone,
I need some help here.
I'm trying to put a new node into my existing HA cluster and sync the data from the master node (there is no data on my new node).
The ip of my new node is 9.54.145.185
I set following configuration:
ha.initial_hosts=9.22.14.21:20029,9.22.58.228:20029,9.22.34.221:20029,100.117.134.244:20021,9.41.160.169:20029,10.160.142.32:20021 (copied from one node in cluster)
ha.host.data=:20031
ha.server_id=200 (a new one)
ha.host.coordination=:20029
ha.host.data=:20031
Other configuration is the same with the configuration of nodes in cluster.
After I start the new server, I can see following in the log:

It seems this node has successfully joined the cluster, but it never get data from the existing cluster. I also tried to add the ip of this node in the list of ha.initial_host, still doesn't work.
I'm using the enterprise version 3.2.3.
Can someone help me figure this out?
