[ovirt-users] Importing data domain

Hi All, I am using ovirt 3.6.3 with 2 data domains. domain1 to store os disks and other to store additional disks for the VM I am more concerned about the additional domain and I have rsynced the second data domain to another file based storage. After sometime, I tried to attach that file based storage to another oVirt DC. When trying importing the data domain, I see a warning like "Storage Domain(s) are already attached to a Data Center. Approving this operation might cause data corruption if both Data Centers are active." Any clue why do I see this warning ? Also is there any better way to import the existing data domain ? -- Satheesaran
