Created attachment 169161 [details] clarified proposal for the preemption note The handbook states in a note on CARP: > If preemption has been enabled, hostc.example.org might not release the virtual IP > address back to the original master server. The preemption setting does the opposite of what I would interpret this sentence to convey. Preemption needs to be enabled in order for the system with a lower advskew value (the original master) to take the address back. In writing this, I wonder if it also needs a sentence on where to enable preemption (master, backup or both...). I'd assume there are very few scenarios, where different settings on nodes in the same group would be useful or necessary. I have attached a proposed change for this note.
I agree fully, the man page's text is the exact opposite, or it is very hard to interpret, which is just as bad. Please commit this, someone. :)
