I don't know why it's stuck. This has never happened to me :-). Neil helped someone recently with a similar problem, and suggested omitting the backup-file. It isn't needed for --grow operations that increase capacity. I also recall some discussions about systemd vs. mdmon issues -- if that applies to you. If omitting the --backup-file fails, I would reboot into a rescue CD with a recent kernel and mdadm version. I recommend www.sysrescuecd.ord for such things. Then use mdadm --grow --continue within the rescue environment. Phil
