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.
