Introduction

opHA introduces the concept of a Primary & multiple Poller servers:

• The Primary is the server that keeps the information of all the pollers and it is where we can read all the information from.
• The pollersPollers, collect their own data, and send that information to the Primary when it is requested. 

...

The first time the pull script runs, it requests all the data for each configured poller. Next time, it requests only the modified data since the last synchronisation. 

Releases

• Fixed issue where with a query to filter which nodes should be moved to a peer could silently fail.
  
• Added safety guard where if more than 90% of nodes on a peer need to be removed then the job will abort unless you force=1 is passed into sync-all-nodes.
