Nope, ar1 (with ad8 and ad10) is the second RAID, both are marked as READY even though one is degraded in the BIOS. ar0: 476937MB status: READY ar0: disk0 READY (master) using ad4 at ata2-master ar0: disk1 READY (mirror) using ad6 at ata3-master ar1: 476937MB status: READY ar1: disk0 READY (master) using ad8 at ata4-master ar1: disk1 READY (mirror) using ad10 at ata5-master In any case, this is water under the bridge for me now.

That was back when I had relevant hardware in my lab.

RAID status issues with Intel MatrixRAID ataraid
This isn't a bug report, just a heads up to anyone using the same setup. This occurred in production, and I don't currently have a non-production hardware on which to investigate this bug and/or create a patch. In certain conditions, even though the Firmware RAID BIOS, says that a RAID is degraded, the FreeBSD driver thinks it's business as usual. In my case this resulted in file system corruption. Relevant output below. FreeBSD version: 6.3-RELEASE-p2 Cheers, Stef Walter BIOS OUTPUT: Copyright(C) 2003-06 Intel Corporation. All Rights Reserved.
