Add "--force" to that line, and it will work.
In this context, "--force" means "yes, I know that some devices are a bit out
of date and that that if there was a write happening while one of the devices
appeared to fail then there could be some corruption of a few blocks in the
array, but I want all the rest of the data and I promise to be careful and I
won't assume that everything is perfect and I won't blame you if a few files
are lost - just do what you can. Please."
