On my Linux software RAID 6 array, I'm currently mid-reshape and 2 drives have been marked as failed. I've swapped them out and added new ones to the array, which are currently marked as spares. The re-shape has a lot of time left and I'm worried that a third failure will happen during that time and kill the whole array. Is there a way to maybe pause the re-shape and do a re-build onto the spares?

Increasing the speed of the reshape (I don't have a full answer for you) can be done by killing off everything else - I find mdadm runs a lot faster if I temporarily disable most of the services my server runs while it rebuilds or reshapes an array. – Xyon Oct 22 '12 at 6:36
@Xyon: Everything's shut off and the file system is unmounted, but even at that I'm still looking at 4 days of pegged disk access for the re-shape. 20 2-TB drives. – David Oct 22 '12 at 9:39
