Using pcmk_delay_max does not seem to be really reliable. I don't like the idea of being dependent from a software thinking "which delay i should choose, depending on the ... weather conditions, any mood ..." I'd like to know what the software is use is doing. Am i the only one having that opinion ? How do you solve the problem of a deathmatch or killing the wrong node ?
