I tried multiple example but none of them returns something. I want to get the first SD available, type=data and available > Required new disk size. 1) storage_domain = instance.system_service.storage_domains_service. list(search: "available >= #{(size * 2**30).to_i} AND status=\"active\" AND type=\"data\"").first 2) Also tested: storage_domain = instance.system_service.storage_domains_service. list(search: "available >= #{(size * 2**30).to_i} AND status=active AND type=data").first 3) Then, I decided to check with only 1 criteria storage_domain = instance.system_service.storage_domains_service. list(search: "type=data").first But all of them returns nothing. What I'm doing wrong?
