Another master need to have the same zone and configuration with the former. When a master is down, I need to switch to another master right away. you can make any slave at any point of time to a new master typically you have *one* master and one slave which is confirured as fallback-master on any other slaves - so in case you primary master fails you change that one to a master with the data it already has just make your changes on that slave which now became the master when you restore the old master you just configure it as slave like before and both just switching roles there is no reason to maintain two masters On 8/22/2018 16:39,Reindl Harald<h.rei...@thelounge.net> <mailto:h.rei...@thelounge.net> wrote: Am 22.08.2018 um 09:15 schrieb Zhengyu Pan: Hi: In my application scenario, I have two master. Each master connect several slave dns. When users update zone, i update these two master respectively in a for loop. However, when any master update fails, i will roll bock. you know, whenever any update, zone's serial will increase. this cause that the serial numbers of zone in two masters are inconsistent. How can i keep these two masters' zones consistent in real time? Is using rsync tool a good way? In the industry, is there a good way to synchronize two masters? why two masters to begin with?
