Hey  
Added a new node to the cluster.  
But it is not getting added?!  
Any ideas?  
Says it has 5 nodes, but node 5 is offline?

Thanks!

What about the new node and current master logs?

@warkolm  
In what sense?  
Master logs show regular activity.  
New logs have no activity in them since I have started it.

As in what's in the logs of the node that is showing as offline?

Sometimes Monitoring can take a small amount of time to catch up, but if it's anything longer than a few minutes then your Elasticsearch logs should show something useful.

Also, what's the output from `_cat/nodes?v`?

According to logs, the new node is not doing anyhing.  
Also, no errors or warnings.

I see the data dir is full.

Running stats, shows there is data on the node.

After a few hours, between 2-12 (went to sleep), the status page is reflecting the new node and its metrics.  
I expected it to be a quick process, hence I raised this issue.  
Thanks!
