I've never understood what a backup controller is good for when you need very reliable/HA-shared storage and a very reliabe/HA-MySQL (*cought*) installation on top off that (or live with the illusion that two processes instead of one depending on two SPOFs make it a dependable cluster) -- apart from very big clusters where a single controller VM with all the dependencies won't cut it because it might become a bottleneck. But I'm eager to learn about the advantages of a backup controller (and the necessary[?] complexity) Regards, BR -- FSU Jena | JULIELab.de/Staff/Benjamin+Redling.html
