But in my dmesg, I'm seeing task md127_reshape blocked for 120
seconds, and when I cat sync_action, it shows reshape. Which
shouldn't it be frozen or something like that? Also md127_raid6 task
is using 100% cpu. I was going to paste the assemble output, but hit
clear instead of copy. It didn't show any errors I saw, just starting
with 6 drives. reshape isn't using any cpu
If I do a cat of /proc/pid/stack, all I get is
[<ffffffffffffffff>] 0xffffffffffffffff
Should I just let it run?
Here's dmesg output for the raid stuff
