You also need to specify the pool as a valid pool to store filesystem data in, if you haven't done that already: "ceph mds add_data_pool <poolname>" And you may not actually need to specify all options — I'd been assuming since it broke but I don't remember if that's actually the case (I think it's changed over the versions). -- 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
