Subject: Re: RAID 10 reshape is stuck - please help

I tried to mount as read-only and got the following error:

bill@bill-desk:~$ sudo mount -o ro /dev/md127 /media/bill/ARRAY3
mount: /media/bill/ARRAY3: wrong fs type, bad option, bad superblock
on /dev/md127, missing codepage or helper program, or other error.

Superblock seems ok:

bill@bill-desk:~$ sudo mdadm -D /dev/md127
You are checking the raid superblock, but mount cares about the filesystem's superblock. Which filesystem is it ? 



I have noticed a lot of this type of stuff in dmesg, repeating every 5
minutes or so:
