Hello, I think we usually have an evacuation api for this. Is there any reason you do not want to evacuate instance, then the volume will stay attached and usuable ? Regards On Fri, Mar 21, 2025 at 4:34 PM Arnaud Morin <arnaud.morin@gmail.com> wrote:
I can partially answer myself. This is a feature, which prevent inconsistencies from nova/cinder.

Now, I am wondering if multiattach could be a partial solution?

Hey team,
Is there any way to force detach a volume when the nova compute service is down? Like when the hypervisor is off, we want to detach the volume and attach it to another instance.
Maybe I'm missing the way to do it, but detach action on nova side seems a synchronous task that I can't force without admin creds.
Thanks for any help,
Regards, Arnaud
