OK I think https://review.opendev.org/#/c/620706/ is the regression because of this:
https://review.opendev.org/#/c/620706/32/nova/compute/api.py@3598 The resize flow passes root_bdm=None to _validate_flavor_image_nostatus which makes it take this else block: https://review.opendev.org/#/c/620706/32/nova/compute/api.py@585 and then we fail here: https://review.opendev.org/#/c/620706/32/nova/compute/api.py@642 When https://review.opendev.org/#/c/561284/ was written that validation code wasn't called during resize. That code had introduced regression bug 1825020 which was fixed in Stein here: https://review.opendev.org/#/c/656666/ It looks like that should fix your problem and is in the 19.0.1 release. Which release are you using for Stein? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1837054 Title: Only volume-backed servers are allowed for flavors with zero disk.
