First, is that the right md number?
Yes.
But also, you can't do that with sudo directly.
"sudo echo check > /sys/block/md127/md/sync_action" will try opening the
"file" with your user permissions which won't work. It's easier to
just
do "sudo -i" to become root, then run the command.
Facepalm. Of course.
