Are there any tools in Fedora to help people migrate an md RAID1 array to btrfs, with data verification checks? For example 1) check for differences between source file sectors on each source drive 2) for each file, if the file format has a checksum, check it somehow and alert on failures The new emphasis on Btrfs is interesting but it is not much help if people copy in files that are already spoiled. If people can still recover a good copy from their md array then it is a good idea to do so. I could imagine using kpartx to script a solution to (1) above, skipping over the md headers. Some kind of shim may be needed to fool the kernel to see a different UUID for each source volume so they can be mounted simultaneously without md.
