This is the linux software raid utility.

This is the very similar with mdadm. But you with mdadm you can force the
raid array to use failed drives without loosing their data. I assume you
will have corruption at the points the array is out of sync but in your case
if all drives are not really dead the array would have gone offline after 2
drives were kicked out so in that case the problem would have been
recoverable if you figure out which drive was the second to be marked
