It went something like this:
cat /proc/mdstat
sudo mdadm --stop /dev/md1
mdadm --zero-superblock /dev/sdh
mdadm --zero-superblock /dev/sdj
mdadm --zero-superblock /dev/sdd
mdadm --zero-superblock /dev/sde
mdadm --zero-superblock /dev/sdc
sudo mdadm --remove /dev/md1
umount /dev/md0
fsck.ext3
dmesg reports successful reshape:
[158623.944746] md: md0: reshape done.
[158624.630207] RAID5 conf printout:
[158624.630217] --- rd:11 wd:10
[158624.630223] disk 0, o:1, dev:sdk
[158624.630228] disk 1, o:1, dev:sda

[158624.630236] disk 3, o:1, dev:sdb
I unmounted the device and performed fsck on it, which detected a nice
bunch of problems:
Free blocks count wrong for group #5641 (32265, counted=11).
Fixy? yes
Free blocks count wrong for group #5642 (32311, counted=57).
Fixy? yes
Free blocks count wrong for group #5643 (33697, counted=1449).
Can you describe the exact set of steps you took performing the
conversion from RAID5 to RAID6 and the filesystem type please.
Dave
