Public bug reported:
With `allow_resize_to_same_host=true` nova removes instance directory on
host after confirming resize.
First resize works fine, although directore is removed.
Second resize fails, because nova cannot mv instance dir to instance_resize.
Workaround: power cycle instance after resize, then directory is created again.
Tested on volume-backed instances (with Ceph).
Env:
Ubuntu Xenial
nova-compute 15.0.2
libvirt 2.5.0-3
Steps to reproduce:
- set allow_resize_to_same_host=true in nova.conf & restart nova services
- create instance (in my case: boot from volume, cinder storage in Ceph)
- watch /var/lib/nova/instances
- resize instance
- observe change in /var/lib/nova/instances
- confirm resize
- both directories were deleted
- resized instance is running
