[ovirt-users] Ovirt Hyperconverged Cluster

I am installing ovirt 4.2 on three nodes. I am using centos with ovirt cockpit. My /sdb is my boot disk and /sda is my local storage, When I started the setup with cockpit I selected the sda but the ansible script stay on sdb. I have fix all changing the playbook manually but in the execution the gdeploy tool stay blocked on TASK [Create Physical Volume] . I don't find any logs. How I can fix that?
