[ClusterLabs] 答复: How to setup a simple master/slave cluster in two nodes without stonith resource

Rorthais， Thank you very much for your help. I do according to your comments and the cluster status is ok now. I want to ask two more questions: 1. This line code in PAF prevent the score to be set. Why does PAF request the prev_state must be shutdown? Could I just set the score if it is not

"In short, I'd recommend separate constraints :) e.g. start rscA then promote rscB, promote rscB then start rscC." I've fiddled around with my code and gotten it to do this. Just out of curiosity, is there an upper limit on the number of individual constraints that we can put in place? 10 or
