From: Allen Landsidel To: Alexander Motin Cc: bug-followup@FreeBSD.org Subject: Re: bin/166589: atacontrol(8) incorrectly treats RAID10 and 0+1 the same Date: Tue, 15 Jan 2013 12:09:29 -0500 The atacontrol(8) man page and handbook page on RAID (19.4.2) both discuss (briefly) hardware RAID and say it is supported. It seems you're calling all the southbridge controllers "software" RAID? That terminology in my experience is used to describe gmirror/ccd disks without a RAID controller or RAID BIOS. In any case, the difference and PR still remain. A 6 disk RAID-10 controller ((1,2),(3,4),(5,6)) with failed disks 1, & 4 (or even 1,3 & 5) will boot and allow you to do your 'magic.' A 6 disk RAID0+1 controller ((1,2,3),(4,5,6)) with failed disks 1 & 4 will not boot the OS. Misrepresenting one as the other in the software is wrong.
