Thanks for sharing your experience. Do you run it in bitmap mode? If not, how’s the perf hit feel (I’m using spinners)? Does it have any ability to correct errors, or does it just cause the drive to drop when they appear? (I hoped it would write the corrected value back during an mdadm array check.) Does it reduce drive capacity at all? If not, I’m thinking maybe I could convert my array to it, one drive at a time, verrrry slowly.

I'm running in bitmap mode, on spinning drives. It reduces the drive capacity, but not by a noticable amount. I've set up my RAID to not haeve a "bad block list" so I _think_ it will try fixing it a few times, and drop the drive if there are too many errors in a row. Should be easy enough to try with a "test" RAID made out of a bunch of files (or even USB sticks).
