Hi, I think you'll need to be more specific here. Which openstack version are you running? Just recently I have been shuffling around instances with live and cold migration (in version Victoria, so quite old), some of them did fail but I didn't have to reset any state or shelve/unshelve instances. I can't recall if the instances were in ERROR state, though. I didn't need to check because after fixing whatever broke the migration I just issued another (live-)migrate command and then it worked. We use only ceph as backend for glance, nova and cinder, which backend(s) do you use? Maybe that has an impact as well, I don't know.

Hello.
I would like to know why we set instance-state to ERROR when resizing/migrating failed? I have a problem with resizing/migrating instances. I must reset state then shelve and unshelve instances to make it come back.
Thank you for your time.
