Could you please show `ceph -s` (and `ceph health detail` if it is not OK)? If the health is OK, what does happen if you try `rados -p ectest ls`? If it hangs too, showing here the result of `rados --debug-rados=30 -p ectest ls` might be useful. -- Mykola Golub -- 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
