I appreciate your taking the time to do that. If it looks like it basically works we'll give it a try and see if the md issues go away.
we have a pair of OSS servers we can try this on with a 200Tb filesystem and not risk losing anything important,
so I think what we may do is compare the 1.8.7 build against a newer kernel, with the 2.1.1 release,
which looks like it is approaching stability for production environments and see how that fares with mdadm
