No hints there - all normal. If you can write to the array, then md_check_recovery must be getting run, and the array is not read-only. So... Is there a 'sync' thread still running? It would be called md126_resync That would stop things from progressing. If there is, what does cat /proc/$PID/stack show for the relevant PID ?? What about cat /sys/block/md126/md/sync_action ?? If that were 'frozen', that might explain it. cat /sys/block/md126/md/reshape_position shows "none" I suspect? I cannot think of anything else that could be getting in the way.
