doing it automatically is not that simple, since at that point we will need to trigger the disk deletion from the engine. So we eventually need for the engine VM to start again from the 3.6 disk and use the REST API from that to remove the new disk for 4.0 engine. Maybe we can simply print a warning to the user to remember that the failed attempt created a new disk and he can remove it from the web admin interface. Yaniv is comment #2 suggestion acceptable on your side? > Maybe we can simply print a warning to the user to remember that the failed > attempt created a new disk and he can remove it from the web admin interface.

Would this increase the likelihood that the next attempts will fail due to size of the storage domain?

Yes, the user have eventually to rollback, start the engine and delete past backups from there. |
