After specifying Michelle Sullivan restore everything , now the system is loaded .
At 10.1 LiveUSB I did zpool import but probably the tenth attempt, he has executed , the same thing happened on the 11 branch. So I removed just in case bad dataset - / var / db / mysql / billing,
After I did the export and rebooted in the hard disk. I am grateful to you about .
