Thanks for your reporting. BTW, I don't like the current way of handling -EIO (not limited to md, and not works well currently). Because if sheep has no disks, it means it cannot store log. It will make trouble shooting almost impossible. Rather than calling leave_cluster(), simply calling panic() or exit() would be enough. How do you think, Valerio and Bingpeng?
