Resize revertion leaves instance directory on the second host with Ceph image backend. As the result the second attempt to resize the instance to the same host fails with n-cpu.log:

Steps to reproduce:
1 Run 2-nodes devstack with Ceph image backend
2 Run an instance
$ nova boot --image cirros-0.3.4-x86_64-disk --flavor t1.nano inst-1
3 Disable the instance host
$ nova service-disable 172.16.1.10 nova-compute
4 Resize the instance to another host
$ nova migrate inst-1
5 Revert resize
$ nova resize-revert inst-1
6 Resize the instance again
$ nova migrate inst-1
7 Check the instance state
Actual result - the instance is in error state.
Expected result - the instance is in verify_resize state.
Check n-cpu.log on the second node, where the instance was migrated. |
