Mirrors used to be created by first creating a linear device and then adding the other images plus the log. Now mirrors are created by creating all the images in one go and then adding the log separately. The new way ran into the condition that cluster mirrors cannot change the log type (in the case of creation, from core -> disk) while the mirror is not active. (It isn't active because it is in the process of being created.) The reason this condition is in place is because a remote node may have the mirror active, and we don't want to alter the log underneath it. What we really needed was a way of checking if the mirror was active remotely but not locally, and in that case do not allow a change of the log. I've added this check, and cluster mirrors can now be created again.
