So this is a subtle difference from your original report which ran
lvcreate a little differently:

  # lvcreate --type mirror --mirrors 1 -L 1G main /dev/sda2 /dev/sdb2

This patch series address problems with the original report with the
"--type mirror" parameter, which uses dm-raid1.c instead of md/raid1.c.
Knowing that detail makes this a trivial matter to fix now, so I'll send
a separate patch for that. But this series should be good to go for the
original issue on the legacy dm mirror.
