Dmitriy, are you sure you waited for completion of all deployment tasks on the compute node? (the ones that configure OVS and Ceph seem to be executed relatively late)

I gave it another try on 9.0 and still believe the approach described in https://bugs.launchpad.net/fuel/+bug/1477475/comments/13 and https://bugs.launchpad.net/fuel/+bug/1477475/comments/14 is the preferred way, thus, fixing the docs and the way we tackle this to make sure workloads are properly disabled/migrated before doing redeployment of a compute node.

We could use an ugly hack to work around the corner case with an OVS bridge, but, as I mentioned in the comments, there are more similar problems, e.g. the one with Ceph (https://bugs.launchpad.net/fuel/+bug/1536115). I.e. the external orchestration that triggers the redeployment process must disable / enable nova-compute and its workloads (or migrate those).

Docs team, I suggest we update the docs as it's described here - https://bugs.launchpad.net/fuel/+bug/1477475/comments/14
