When falling asleep in the train yesterday, I think I got the answer to this question. > In case of the following situation: > > nodes node1 and node2 are disconnected > At t0, split brain > At t1, node1 becomes primary > At t2, node1 becomes secondary > At t3, node2 becomes primary > At t4, node2 becomes secondary So node1 is "old" and node2 is "young". > At t5, node1 becomes primary > At t6, node1 becomes secondary Now node2 is old and node1 is young. > At t7, node2 becomes primary > At t8, node2 becomes secondary Now node1 is old again. Keep on doing this and I guess you have your answer. Please correct me if that's wrong and falling asleep did not solve this question :) Regards Dominik > At t9, node1 becomes primary > At t10, node1 becomes secondary > At t11, node2 becomes primary > At t12, node2 becomes secondary > At t13, node1 becomes primary > At t14, node1 becomes secondary > At t15, node2 becomes primary > At t16, node2 becomes secondary > At t17, node1 becomes primary > At t18, node1 becomes secondary > At t19, node2 becomes primary > At t20, node2 becomes secondary > At t21, node1 becomes primary > At t22, node1 becomes secondary > At t23, node2 becomes primary > At t24, node2 becomes secondary > At t25, split brain is fixed > > "discard-older-primary" policy will make node2 from t23 the sync source > "discard-younger-primary" policy will make node1 from t1 the sync sourc, > or node1 from another time than t1 ?
