Hi everyone,

Can there be such configuration: 6 machines in the one cluster, but the HA uses only 4 of them?

Thanks for your help,

Yes, you can.
You can enable HA just for vms you need for.Just go to Datacenter -> HA and enable HA for vms you need HA.The remaining vms will be handled manually by you.

I will specify, "vms" in the sense of "virtual machine"?
But i mean 6 machines in the one cluster like "6 bare metal machines members in the one cluster".

Please, forgive me for my bad english.

As long as the cluster configuration is unique to the entire cluster I don't believe you can do that.
You need to have 2 separate clusters for that.
But wait for a confirmation from somebody else to be sure.

Yes, you can. Search for failoverdomains - I think this is what you are looking for. Some description can be found here https://access.redhat.com/documenta...tration/s1-config-failover-domain-cli-CA.html

Yes, it seems that this is exactly what I was asking about.
Remains to try how it works.
Thank you very much for the advice!
