Hello again, Little bit of progress since I last dropped a message in (sorry for the duplicate, didn't think the initial one got through). The kernel has mdraid built into it and all disks are using 0.90 superblocks, all 'fd' partitions, but only 2 or 4 disks are being recognised and applied to the freshly created raid array which works fine when mounted on any other OS. Any suggestions for what could cause disks to be overlooked by mdraid before the root device is even attempted to be mounted would be very helpful, I'm now totally at a loss as to what to do from here. Kind regards, Ricky Burgin -- 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
