Hi Kuai,
Here is the first verion of the fixed patch, I fail the io that is
waiting for reshape while reshape can't make progress. I tested in my
VM and it works as I expected. Can you give it a try to see if mdadm
can still assemble?
Assemble seems to work fine and the reshape resumed.
I see this error appearing:
md/raid456:md0: array is suspended or not read write, io accross
reshape position failed, please try again after reshape.
From what I can see in your patch, this is what is expected.
Best regards,
Johan
