[snip] I read your articles on CTL HA, BQ and BeaST, and just wanted to say they are amazing, good job! One thing I=C2=B4m wondering about though is if you can claim HA with jus= t two nodes, usually you need at least three, where the third is a tie- breaker. Otherwise with your current setup, both systems may loose contact with each other while both still being powered on, leading to potential split brain situations. What are your thoughts about that? /K
