Did you change ceph.conf and set one of the log options? The default config writes to /var/log only from the daemons, not from the libraries. Can you please share your configuration. As for needing to be able to read client.admin, that file is not changed by the ceph services starting, you can safely chown/chmod it. Alternatively, give the non-root user a new key, and authorize that with "ceph auth add". -- 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
