Hi guys,

i'm looking for a good solution if i need to evacuate instances from a broken compute node.

So normally all my instances are stateless and i don't use shared storage for ephemeral and/or root disc's. I've found nova evacuate command but it needs a target host and the find host for evacuate is not ready yet link text

My prefered step would be an automatically evacute instances from a failed comp node like this one: link text

Other way is to use heat/Bosh/JuJu whatever, but there would be a problem with these "broken" instance because they can't be delete and the attached volume can't detach.

How do you handle this topic ?

Cheers Heiko
