What version of mdraid? 0.97? or 1.x?

0.97 is in-kernel, and deprecated - as in "if it ain't broke, don't fix 
it. If it is broke, it's not supported". I think there are a fair few 
people who depend on it, though, so it tends to get fixed if something 
goes wrong.

1.x is assembled in user space, so there are probably races with other 
stuff in user space for completion. I run a somewhat messy boot stack, 
but iirc my root space is just "rust, mdraid, lvm, root partition", and 
it works just fine. But I do run systemd, and I might have had to make 
sure there's something in the boot stack waiting for each bit to 
complete in order.

My /home stack has dm-integrity between rust and raid, and boy did that 
really cause some grief getting that to behave. But that makes sure that 
my raid-5 never sees a corrupt read, so I can recover from a damaged 
disk as well as a lost disk.

I - allegedly - know about raid :-) , so if you give me a bit more info 
I might be able to help. Or I might not ...
