Hi, 'm unable to add host to engine. I have fresh engine build, cleaned host, dropped and recreated DB. I'm adding host using rest¹. Command InitVdsOnUpCommand is called during operation, having getStoragePoolId() equal to 00000001-0001-0001-0001-0000000000c1. However, there's no storage domain in system — it's empty installation, and I'm only creating host yet (so I cannot have any storage domain). Because of that, following code: StorageDomain masterDomain = getStorageDomainDao().getStorageDomains(storagePoolId, StorageDomainType.Master).get(0); in method: org.ovirt.engine.core.bll.InitVdsOnUpCommand#runConnectHostToPoolEvent produces NPE, which is probably cause of host marked as nonoperational. ——— If I'm doing something wrong, plese advice.
