Thank you for your reply. How to switch slave to master in real time? Does bind have command?

Because I need to a master as a cold standby. 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

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
inconsistent. How can i keep these two masters' zones consistent
time? Is using rsync tool a good way? In the industry, is there
way to synchronize two masters?
why two masters to begin with?
