[ovirt-users] 3.6 : Hosted_Storage unattached

Hi, I installed a new node with a new hosted engine, version 3.6, added a data domain, but I can't see the hosted_storage. I tried to use the "import storage" on it but it keeps having unattached status, and in the logs I can see : "2016-08-09 05:39:32,821 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ajp-/127.0.0.1:8702-1) [] Correlation ID: 1d9c8f67, Job ID: 6e75d61e-3140-4f1c-a301-e683ddc28b1f, Call Stack: null, Custom Event ID: -1, Message: This Data center compatibility version does not support importing a data domain with its entities (VMs and Templates). The imported domain will be imported without them." Any ideas ?
