Hello. Nobody can help me with point 2? Best regards.

Hi all! I just configured a 3 node Cluster, where 2 nodes have drbd shared storage where 1 Virtual machine can migrate between node1 and node2. Node3 is running 1 virtual machine but is not needed HA on it, so Node3 is used for quorum. My cluster config is: Cluster Status for mycluster @ Wed...

Hi. Somebody knows if is possible to create a 3 nodes clusters, where 2 nodes share a drbd disk and VMs, and the 3rd node only used for quorum and one local VM? thanks.

Thanks for the answe Dietmar, I'm just learning by myself in this. I read in https://pve.proxmox.com/wiki/Two-Node_High_Availability_Cluster#Testing about these kind of test and I was thinking that VM auto migrate with an uncontrolled failure. So my question is: Is it possible auto migrate a...
