[SOLVED] Does HA cluster work with two group ?

[Quốc Hưởng]

This is my situation:
-I have 5 nodes in 1 cluster. ( Node 1, Node 2, Node 3, Node 4, Node 5)

1-Now i want to migrate (Node 1 <-> Node 4, Node 2 <-> Node 3) if 1 node fail. Does it possible ? I know the priority is used but just 1 node or more 2 nodes with same priority, not the permanent one.
2-I have 2 HA groups: Group 1 ( Node 1, Node 2), Group 2 ( Node 3, Node 4, Node 5). Do 5 nodes work with HA together, or just those nodes in single group. If they work, suppose node 1 fail, VMs can migrate to Node 2, Node 3, Node 4, Node 5 ?

Can u guys help me about this problem, i cant find this on google.
Thanks very much

Did you check the docs? If I understand you correctly, then yes, possible.

so like the post above, if 2 nodes in group 1 down, VMs will migrate to the group 2 ( without "restricted" ticked ), and Stop ( with "restricted" ticked ).
If i set priority of Node 3 in group 2 to highest, then Node 2 in group 1 off, Do VMs in node 2 move to Node 1 or move to Node 3 (different group). what Proxmox do when Node 3's priority = Node 1's Priority ?

Thanks for your answer.

You group nodes together and set a VM to be in one of those groups. If you set priorities right, then whichever node with the highest priority is alive will get the VM.

So VMs can move to other group which has highest priority node?

Still not, please read the docs. The group holds a set of nodes that are in question for HA of a VM that is associated with that group.
