What happens to vertica when my node shuts down
What happens to vertica when my node shuts down, for instance, I issue a 'reboot'. On RH7, it looks like my vertica process just gets killed when vertica_agent shuts down? Is it ok to just reboot a node, or should I first shutdown the vertica process, and if so, what is the safe way to do this?

When you shut down (i.e. reboot) a node every process - including Vertica - shuts down!
The Database "Restart Policy" enables you to determine whether or not nodes in a K-Safe database are automatically restarted when they are rebooted.
See: Setting the Restart Policy
The node will recover once it's restarted.
