Yes, indeed! Another lesson learned.
This might have prevented numerous cases in the past when disc surface
errors occurred while enlarging and resizing a raid array. But all
those serious incidents where handled perfectly and flawlessly by the
software raid module. Congrats to all kernel developers here. The raid
module is far more flexible, error prone and stable than any hardware
raid solution I've seen so far.
