Hello,
I started with an all-in-one installation of ovirt 3.3.2 on a FC19 host.
After the initial setup was done, I created a new datacenter, cluster
and storage domain in the engine and moved the single host in the engine
to the new cluster. After that I deleted the automatically created
storage domain, local datacenter, etc.
It seems, however, that the new master storage domain still contains
some references to the now removed old storage domains in its metadata.
Here's the metadata, extracted from the tags of the VG. I got them using

New subject: [Users] Old storage domain ID left behind in master storage domain's metadata
Hi,
How exactly did you delete the storage domain and dc?
From the steps you are describing, since the host was not part of the
DC when you removed it you had to have used 'force remove' on the DC, which does
indeed remove the DC and the domain from the UI, but that is *all* it does.
It only
removes references to those objects from engine's DB, it does not remove the actual
storage domain (VG).
Thanks,
Gadi Ickowicz

Regarding the way to remove the old DC and move from local to iSCSI storage, you can:
1) deactivate the last domain in the DC (After detaching all other domains in the DC)
2) remove the DC (while there is still a host in the DC)
3) remove the domain regularly (which should clean the storage itself
4) move the host to the new DC
Regarding the fact that the other domain was removed cleanly and is still visible in the
metadata that is very strange. Do you happen to have logs from the creation/deletion of
that domain?

I am not really sure what the recommended way is (adding Nir Soffer, hopefully he can help
or point us to the right person).
Maybe you can try manually deactivating and detaching the domains from the pool using
vdsClient on the SPM host
(for each of the domains):
deactivateStorageDomain <domainID> <poolID>
detachStorageDomain <domainID> <poolID>
if you have vdsm configured for secure connection (default) then you can ssh to the host
and run the following command: vdsClient -s 0 [commands from above].
Otherwise you don't need the -s.
I guess you already have the domainID (VG name) and the poolID (from the previous mails
you sent). Not sure if this is the correct way to solve this problem - Nir?

The easy way to do this is to use vdsClient tool:
vdsClient -s 0 forcedDetachStorageDomain <domain UUID> <pool UUID>
If you are not using secure connection (ssl=true), remove the -s option.
