Are there any issues with expanding vdevs via disk replacement where those issues are based on the original size of the disks in the vdev? In other words, let's say I have an 1TB X 8 disk RAIDZ2, and I updated those disks to 4TB, then to 8TB, and then one day to 20TB over time. Does the starting size of the vdev and how it's initially laid out cause any problems once expanded 10 - 20X it's original size?
