i've never looked at yaird in detail -- but you can probably use initramfs-tools instead of yaird... the deb 2.6.14 and later kernels will use whichever one of those is installed. i know that initramfs-tools uses mdrun to start the root partition based on its UUID -- and so it should work fine (to get root mounted) even without dorking around with mdadm.conf. but if you want to stick with yaird: On Fri, 3 Feb 2006, Lewis Shobbrook wrote: > My mdadm.conf (I never needed to use at all previous to the yaird system) is > as follows... > ARRAY /dev/md0 level=raid1 num-devices=3 devices=/dev/sda2,/dev/sdb2,/dev/sdc2 > auto=yes > ARRAY /dev/md1 level=raid5 num-devices=3 auto=yes > UUID=a3452240:a1578a31:737679af:58f53690 > DEVICE partitions some wrapping occured there i'm guessing... you might be a lot happier if your /dev/md0 also specified the UUID rather than the individual devices. this is probably the source of your troubles. you can get the UUID by doing "mdadm --examine /dev/sda2". or you can try: mdadm --examine --scan --brief ... just prepend "DEVICE partitions" in front of that and you should be happy. -dean - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
