Re: ip-tiebreaker quotes need explainging

[Rick Rodgers <rodgersr@xxxxxxxxx>]

Thanks for replying to me especically on a Sunday. I was familiar with everything you
said. The question concerned not being able to use the tiebreaker to form quarum on STARTUP.
Why is this?

Also Lon sent me a URL  to a doc I need but it seems the URL is stale. Can you help
me? Here is the URL:

Hi,

The ip tiebreaker is primarily used during network split-brain
situations in a even numbered (2,4, etc.) cluster.  The ip tiebreaker
provides the extra vote (to form a quorum (50% + 1)) to determine who
should be the next/ new master.

cheers,
Michael
