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 ...
