Public bug reported:
If an instance is booted from a volume backed snapshot with
ephemeral(s), it cannot be resized down to a flawor with disk size is
lesser than original flavor disk size.
Steps to reproduce:
1 Prepare flavors
$ nova flavor-create t1.nano-2-e auto 64 2 1 --ephemeral 1
$ nova flavor-create t1.nano-1-e auto 64 1 1 --ephemeral 1
2 Prepare a volume backed snapshot
$ cinder create 2 --image-id cirros-0.3.4-x86_64-disk --name boot-vol
$ nova boot --boot-volume <boot-vol-id> --flavor t1.nano-2-e inst-1
$ nova image-create inst-1 snap-1
3 Boot an instace from the snapshot
$ nova boot --image snap-1 --flavor t1.nano-2-e inst-2
4 Resize the instance
$ nova resize inst-2 t1.nano-1-e
5 Check status of the instance
$ nova list
Expected status: VERIFY_RESIZE
Actual status: ACITVE
Environment:
DevStack on current (the last Nova commit
