But it really need the patch you gave several days before. I already 
tried without the patch, reshape can be
stuck even selinux is set to Permissive.

And it's a problem with systemd and selinux too. If I run mdadm --grow 
--continue /dev/md0, the reshape can start.
If I run systemctl start mdadm-grow-continue@md0.service, it can't 
start. I'll look for the answer.
