VME management VM - automatic failover

[chypsa]

As the title says, I'm trying to figure out whether the VME management VM is supposed to failover to a new host if the host currently holding it goes down. This is a lab environment hosted on a HyperV host, but I think it makes no difference.

I'm testing with the latest public version, ceph storage, 3-node cluster. The mgmt VM is on ceph storage, and set to Failover mode.

I turn off the primary node (currently holding the mgmt VM) and...nothing.

I was hoping that the system would recognize the importance of the management plane and start the VM on a different node out-of-the-box, but that simply doesn't happen. 

Is this by design? Or maybe I misconfigured something and that's actually supposed to be working, but it's only not working in my lab?

What's the idea?

Hi @chypsa 
In my opinion, the management VM does not automatically fail over to another host if its node goes down. Even though it’s stored on Ceph and marked “Failover,” the cluster doesn’t treat the management plane like a regular workload VM.
It stays down until you manually start it elsewhere or set up extra HA tools. The “Failover mode” you see applies to guest VMs, not the management VM itself.
So what you saw in your lab is by design. If you want automatic recovery, you’ll need to add external HA for the management plane.

Hope this helps.

Hello Sanika,

thanks for your response! That is in line with my findings, but I wanted to be sure.

I did eventually find a solution using Pacemaker.

Kind regards,
