You're one tiny problem away from that whole array collapsing and you're worried about this one fussy disk? I don't understand your delay in immediately getting a replacement drive in this array unless you really don't care about the data at all, in which case why have a RAID6?

There's no more dying drives in the array, 2 out of 7 died, they are
on RMA soon. (when I can get to the post office).

I did see 5 pending sectors on 1 HDD after the reshape finished
though. I don't care much about the data (it's not critical), RAID6 is
just so I can have one large volume, some speed increase and a bit of
redundancy. If I had them all as single volumes I'd have to use mhddfs
or something to make it look like 1 logical volume. Or even use some
kind of LVM perhaps.
