I can certainly imagine a few different ways to have partition tables that make more sense than the typical Wintel version. >Maybe divide the raid into smaller disks?! Absolutely, if that is your requirement. I have done this. It gives you the usefulness of smaller disks with the speed and reliability of the RAID. More importantly, The hardware should be considered largely immutable. For reliability reason, I want the hardware to have its settings in the safest manner possible, which means not taxing flash ram with too many rewrites. The place for the logical layout of the disks is in the partition table on the disk. One reason for this: what if the controller dies? In fact, I'd like the controller to store its RAID setup on the disk as well. Maybe even on all of them. Of course, if the partition equals the entire disk, great. The table will be really short. In fact, I want a number of backup partition tables (a la backup superblocks). If you've ever had 70 people waiting to be able to do any work while you try and restore a disk that had the partition table scribbled on, you appreciate what I am saying. -- The highest quality of attention we may give is love. http://www.hacksaw.org -- http://www.privatecircus.com -- KB1FVD - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
