See my other mail, log did not reveal much. Other than that it made me look at the sockets. But looking at the socket-states, I think the sockets on the OSD that is going down are not correctly closed. And so osd.0 thinks it is still connected. And osd.1 and osd.2 are without connection to osd.0, so they are correct in suggesting that it is dead. --WjW -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
