Re: Maximum number of controllers & adding controllers

 

Fuelers, as far as know, deployment or operation breaks if:
a) we add controllers to existing deployed environment (let's say we had 1,
then we add another one in attempt to make it HAed)
b) we add more than 3 controllers in HA mode, regardless of if 3 were
deployed and we add 1 new, or we try to initially deploy 4.
And we had this limitation for the very beginning, our UI just was not
handling this situation - so now we are fixing UI behavior.

Vladimir, can you please update with latest status on this, and provide
short info on why we have such limitations if it is the case?

Thanks,
