I'm running a master-master replication with read-only second master. Now since my binary logs are not getting replicated in my passive master.
- Should I need to enable
--log-slave-updates? If I enable this, will I be able to take binary log backups from my passive master? If I enable it in passive master, I should not enable the same on active master right?
If I enable --log-slave-updates in my active master also, consider the case of a disaster where in my primary master has a issue, then I will make my passive master the active one and point my application to my new master. Now my new master will be generating binary logs which will be waiting to replicate to my actual master (which is down now). SO what happens when my actual master comes up? Binary of my secondary master gets copied to my primary without any issues?
- While enabling --log-slave-updates, should I have attn on any other parameters as well.?
Thanks!
