Bug Description

(see discussion in https://bugs.launchpad.net/fuel/+bug/1442475)

Disk partitioning of controllers should be reset to default in case of changing glance backend. Currently that doesn't happen, so we prohibited changing glance backend via hack on UI:


After fixing this issue properly, please revert it.

I understand. But since we have that hack on UI this bug is fixed for 6.1, but the root cause of this issue (backend bug) is not gone and may affect us in future. So that's why 7.0 and Medium priority.

I don't think that this bug has to be considered as of High priority. This seems to be rather tech debt issue of a Medium priority, so can be pushed to early-8.0.

Changing Glance backend is blocked already in UI (if there are any controller nodes pending to be added, change is blocked) and a workaround is available (just re-add pending controller node) if user will do this through CLI or API. IMHO we can move it to 8.0

Proper fix for this issue require changing a mechanism which adds node to cluster. Volume configuration must not be saved to persistence until provisioning is started, otherwise the only way to fix it is to re-add node every time we change anything about disk layout.

Changing priority to medium because workaround is applied on UI side. Proper solution requires blueprint implementation

Hi Fuel Python team, could you please pay attention to the issue?

It is the reason of the following but in UI:

We have this dirty workaround in UI because of the issue with disk partitioning.

I guess you're joking. It's certainly a bug. I understand that there is no technical capability to fix it now. That's why the bug was filed - to make sure that a dev team aware of such an issue and will plan refactoring of Nailgun accordingly.
