clustering: master versus node

[chamelion]

hey guys,

kind of an annoyance more than anything - have set up a cluster with a master and a node. question is why should the node have all the information about the master? don't you want the master to control a bunch of nodes, but not vice versa?

The node does not have 'all' information about the master. But It have enough information to take over the master role when soemthing fails.

don't you want the master to control a bunch of nodes, but not vice versa?

If the master fails a node need to become master.

Will the VM and KVM in the failed master be available in the new master? when the original master fails?

Or do you have to recover the KVM and Vm's from the backups?

(provided that backups are available)

Currently not. But we are working on that feature (when the vm is on shared storage).

yes.
