mysql replication is not working (backup not uptodate)
We need to reinitialize the replication I think. The backup server was down, I restarted it, but replication is showing an error.
show slave status gave this error.
Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: 'Could not find first log file name in binary log index file'
Last_SQL_Error: Relay log read failure: Could not parse relay log event entry. The possible reasons are: the master's binary log is corrupted (you can check this by running 'mysqlbinlog' on the binary log), the slave's relay log is corrupted (you can check this by running 'mysqlbinlog' on the relay log), a network problem, or a bug in the master's or slave's MySQL code. If you want to check the master's binary log or slave's relay log, you will be able to know their names by issuing 'SHOW SLAVE STATUS' on this slave.
Any volunteers to reset the replication? We'll have to copy the master db using rsync and restart the replication from new copy.
