Hi thanks for all the answers,
I only want that when master fails the slave will be the new master and do 
everythink that the master has before done. So I have more time to repair the 
master.
I have to change the slave to master because I need write access to the mySQL 
databases.

Sure that when mySQL data on the master are damaged I will have same problems 
on the slave, but for this I have an undependent data saving, not realtime but 
acceptable. Sure I need in this case more time to repair the whole system.

slave to master:
Like this:

Is this the way to go?

thanks 
Thomas
