In 10.2.2 when running "ceph osd metadata" (defaulting to get metdata for "all" OSDs), if even 1 OSD is currently marked "down", the entire command fails and returns an error: $ ceph osd metadata Error ENOENT: - One OSD in the cluster was "down", I removed that OSD and re-ran the command successfully. It seems that the "metadata" command should be able to dump the data for the OSDs that are up and ignore the ones that are down. Is this a known bug? -Wyllys Ingersoll Keeper Technology, LLC -- 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
