For example, a 3KB CSS file served by a webserver to 400 users, will be read just from one OSD. 400 users directed to 1 OSD while (in case of replica 3) other 2 OSDs are available? -- 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
