How do i change the ISP master controler to another structure node ? If the master controler get fuked up without backup...
The laves contain only partial data (the data for their own server), so you can not make a slave the master for the other servers. If you need several masters, see mirror setup guide.
i dont need several masters, is more like if the master have a major problem how do i configure a new master ?
Take care that you have a backup of the ispconfig mysql database and the mysql.mysql database so that you can restore them on the server that shall be the new master.
Mysql databases are normally backed up with mysqldump. There is also a backup script available that backups all relevant parts of a ispconfig system: http://www.howtoforge.com/forums/showthread.php?t=41609
