SLAVE aware of binary log file switch in mysql?

0 votes
30 views

Given a MASTER and a SLAVE.

When launching the SLAVE, it knows about the binary log file used by the MASTER and the position in that log file.

Say the binary log file (on the master) has reached its maximum size, so that it has to switch to a "+1" binary log file: does he inform the SLAVE of that switch so that the SLAVE updates its information about the MASTER status?

I'm readind the documentation http://dev.mysql.com/doc/refman/5.1/en/binary-log.html and dont see what
is happening while slaving.

The master does not "inform" the slave via an immediate communication channel, but the slave knows how to keep up because the end of the binary log file contains continuation information
- i.e. the name of the next log file to fetch.

We currently have a problem with a master slave setup running mysql 5.0.

This is one of our legacy servers which are in the planning to be upgraded, however in order for this to be done the replication needs to be up and running.

The problem we have currently however is that the binary logs on the master was moved to a seperate partition due to disc space restrictions.

A new binlog file called mysql-bin.1 was created and everything seemed to work fine.

However, the moment the file reached the file size of 100Mb, it does not go on to create a new binlog file called mysql-bin.2 and the replication fails stating that it is unable to read the binary log file.

Thus far we have done a flush logs and reset master , but the same problem occurs, where it creates mysql-bin.1 and the moment it reaches it's max size and suppose to create a new file, it stops and
does not create the new one.

I really hope this makes sense, and that someone can perhaps point us in the correct direction.

Looking for some help configuring 5.0.45 master-slave replication. Here's my scenario...

We have a heavily loaded 30gb 5.0.45 DB we need to replicate via master-slave configuration to a new, beefier server running same mysql 5.0.45, and then cutover to the new server. Due to extreme SAN congestion and a grossly overloaded master server, our DB dumps take 5.5 hours. But we cannot afford that much downtime or locking during the replication transition; we can manage 10-15 minutes, but more is very problematic.

I understand that "FLUSH TABLES WITH READ LOCK" will lock the tables for the duration of the 5.5 hour dump. Is this true?

If so, we'd like to dump/initialize/sync slave WITHOUT any locking anything the master for more than a few seconds if at all possible. Will this give us the dump we need?
