[Users] How do you move an host with local-storage into "regular" Data Center?

[Gadi Ickowicz]

Actually to remove the the last domain in a DC the following steps will do it in and clean up everything without resorting to manual steps:

1. Deactivate and then detach all domains in the DC except last one
2. Deactivate last domain
3. Remove the datacenter (this takes a while since actually the host has to contend for SPM again, like reactivating the domain, in order to remove the DC)
4. DC should be removed and domain should remain unattached -> now domain can be removed
5. Move host to maintenance and switch it's cluster to proper dc (should now be possible since it's DC has been removed and is now blank) or move the host directly to proper cluster

One thing to note when using force remove for DC is that it does *not* clean up the actual storage - only references to it from the DB (and that is why it disappears from the UI). You have to manually go to the host and clean the storage itself to free up that space

Well, I tried but then there was always something impossible to do,
i.e. the Local Storage Domain was the only SD so, beeng it the Master
SD, it wasn't possible to remove it...
something like "the chicken or the egg" dilemma.

That worked. I was just trying to avoid that "forced" option, but you
confirmed me it was the only one.

Thank you,
Giorgio.
