Mark Thanks, I moved to another directory to keep it as a backup. I moved it back to flow.tar and cluster is back online. Make sense, I will make sure workflows are stopped prior restart.

So it appears that you restarted while a request was being replicated to the nodes. Typically, the answer to this is to rename flow.tar.stale to flow.tar and restart the Cluster Manager. If you simply remove the flow.tar you are effectively deleting your entire flow, so be careful with that! When you say you "moved the stale file" what do you mean? You renamed it, removed it, moved to another directory to keep it as a backup?
