Can you describe the criteria for MD considering a block as faulty?
I'll try to answer this having followed some of the discussion around it.
Thanks a lot for the explanation!
Once the controller or power issues are resolved, the bad block list can be
administratively modified or cleared.
Ah, that's good.
I don't think mdadm knows whether its constituent devices are SSDs.
In block/cfq-iosched.c I see a test that looks like this:
if (blk_queue_nonrot(cfqd->queue) && cfqd->hw_tag)
return;
If that isn't conclusive, putting a note into the mdadm man-page is probably
the best one can do.
