Err, you have two RAID volumes, one degraded, and one ok. ar0 is apparently the one that is ok (drives 2 and 3). What is more odd is that it isn't seeing a RAID config at all for ad0 and ad2 (drives 0 and 1). -- John Baldwin _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
