That's giving "permission denied" even with sudo, and with setenforce
set to 'off'.
This can happend if you run :
$ sudo echo check > /sys/block/md127/md/sync_action
which fails because redirection is done by the shell before the
sudo command runs. Use:
$ sudo bash -c "echo check > /sys/block/md127/md/sync_action"
