https://bugzilla.kernel.org/show_bug.cgi?id=217965 --- Comment #43 from Eyal Lebedinsky (bugzilla@xxxxxxxxxxxxxx) --- Thanks Ojaswin, The mount option did the trick, things are drastically faster now. I am now finishing the actual copy that I was unable to complete. The reason I ask about the raid is that it writes so slowly that I wonder if it is just the looping thread or maybe there is something more. The large difference between what the array reports compared to what the members show (in iostat -x) is beyond what I expected as the array write amplification. I will keep watching this thread.
