I believe both support Galera replication. > I was wondering about pacemaker because I know quite well how it works and > I need a vip/automatic failover I regard a VIP as being entirely independent of replicating database content. > Galera seems a different approach that I have to study and test estensively > before place in production, instead pacemaker is a well know solution to > me. Yes, but if you are trying to replicate database content, how does pacemaker help with this? Pacemaker can quite happily provide you with a floating virtual IP address which is guarenteed to be on one of your database servers, but it doesn't (as far as I know) have any mechanism for replicating the database content between those servers. > Is drbd approach obsolete or solid? I would say that DRBD is a solid solution provided you only have two nodes and they have very good connectivity between them. However, replicating the data at disk level is a very different matter from having a DBMS such as MySQL understanding what is on the disk (and for that matter, what it has cached in RAM). > About the degraded status I read on web there is a specific configuration?
