Hi all, Steven Dake proposed a solution* to make MD layer and tools to be cluster aware in early 2003. But it seems that no progressing is made since then. I'd like to pick this one up again. :) So far as I understand, Steven's proposal still applies to currently MD implementation mostly, except we have bitmap now. And bitmap can be workarounded via set_bitmap_file. The problem is that it seems we need a kernel<->userspace interface to sync the mddev struct across all nodes, but I don't find out how. I'm new to the MD driver, so correct me if I'm wrong. And you suggestions are really appreciated.
