It has all the popular ideas that I consider very brave indeed: RAID6, LVM2, growing arrays in-place, growing filesystems in-place, and of course VM images on top (following the usual logic I guess that they will be sparse). It has been my misfortune to see much the same audacious plan setup by optimistic predecessors in a few workplaces, and then having to turn that plan into a less brave one in a hurry when it ended up as it would. But at least in your case it is just a home setup. -- 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
