How to control which VE runs on which node in HA cluster ?

[AhmedF]

Hi,

I'm having a complete proxmox cluster with HA working just fine and HA VEs are moving around the 3 nodes when anyone fails and I've no complains
but I'd like to control which VEs runs on which node as I've here 3 nodes and like to balance the load of 30 VEs to get 10 per node , is there anyway to control this ?

I've them all on a shared SAN so I just need to mark these 10 VEs for the first node and so on and when anyone fails it should go to node #2 then node #3

is this possible ?

I'm running here the latest proxmox cluster software

root@proxmoxa:~# pveversion -v

Thanks in advance,

You need to configure "Failover domains" manually in the cluster.conf file.
Each node in the failover domain can have a priority thus setting a preference for where a VM will run.

Then you assign HA VMs to the failover domains.

If you search the forums you should find the info you need to configure this, I know I have posted it before.
