Hi there, I want to realize a rather complex setup, so I have a couple of questions:
The cluster (as a shared nothing variant) should provide: * 4 services (=server) depending on each other. * 3 of them can only be realized as active/passive failover, synched with DRBD (M/S) * The servers running the application will be Virtual Machines. So I will end up with three master-slave pairs each providing a VIP with a shared drbd-device in a master-slave setup. Most resources could only run on one of two distinct server nodes (active/passive). In sum I will have eight nodes resp. VMs Would you recommend the administration of all nodes with a common corosync/pacemaker cluster? I am a bit afraid of having too many location and collocation constraints for all these resources. Is there a way to define subclusters? How would one bind a resource group to specific nodes - as a constraint to hostnames? Or would it be better to have 4 two node clusters communicating on disjunct/ subnets, with the advantage of a less complex crm configuration? Is there a neat method to administer four separate clusters from a console or workstation? Without introducing a new SPOF?
