MySql Master Master out of sync

Question

I have 2 MySql nodes with Master-Master Replication set-up. MySql1 has read and write access and is in current state. MySql2 has only read access and stopped working due to space issue. How can I fix this issue and resync it.

Answer 1

Given the 'Could not find first log file name' error means Mysql1 has rotated away its binary logs.

You will need to reinitialize Mysql2 as if it where a new replica.

RESET SLAVE ALL on Mysql1 to ensure it forgets about its MySQL2 before beginning.
