Thanks, i solved putting all the Storage domains in maintenance manually changing the status to the value of 6 in the postgres database like you suggested.

After that i could remove the data center from the ovirt management interface.

Thanks again for your help

Claudio

ah yes, it's generally a good idea to move them to maintenance in the case you describe

you can brobably change the status manually in the database, the table is storage_pool_iso_map, and the status code for maintenance is 6
