So, Is it time to start thinking about deprecating the old 0.9, 1.0 and 1.1 formats to just standardize on the 1.2 format? What are the issues surrounding this? It's certainly easy enough to change mdadm to default to the 1.2 format and to require a --force switch to allow use of the older formats. I keep seeing that we support these old formats, and it's never been clear to me why we have four different ones available? Why can't we start defining the canonical format for Linux RAID metadata?
