[ovirt-users] Sync Error on Master Domain after adding a second one

[Stefano Stagnaro]

This is what I've done basically:

1. added a new data domain (DATA_R3);
2. activated the new data domain - both domains in "active" state;
3. moved Disks from DATA to DATA_R3;
4. tried to put the old data domain in maintenance (from webadmin or shell);
5. both domains became inactive;
6. DATA_R3 came back in "active";
7. DATA domain went in "being initialized";
8. Webadmin shows the error "Sync Error on Master Domain between...";
9. DATA domain completed the reconstruction and came back in "active".
