Hi, I have read some threads in this forum, but could not find answers to my questions. I’d like to configure a single FT VM on 2 nodes and 1 SAN.
Question 1, if node 1 (happens to be the primary node with the VM running) is down for few minutes or hours, node 2 will take over the FT VM, but it cannot make the VM redundant. What will happen if node 1 comes back online (without any changes) to the cluster, is this allowed? if node 1 is allowed to join the cluster back, will node 2 start replicating the FT VM to node 1? to the same VM or a new VM?
Question 2 is the opposite of case 1, node 2 (secondary node, no VM running) fails, no failover occurs. If node 2 is allowed to join the cluster back, will node 1 start replicating the FT VM to node 2? to the same VM or a new VM?
Question 3: What will trigger failover, will it occur only when there is complete hardware failure? or will the failover be triggered by simple events such as:
- one local disk failure, even though RAID still kicks in, i.e. storage is still online
- RAM issue
- any one network interface is down
- one fan failure, etc.
