Hi, >From the mdadm manual: "-b, --bitmap= [...] Note: external bitmaps are only known to work on ext2 and ext3. Storing bitmap files on other filesystems may result in serious problems." I was planning to store the external bitmap on an ext4 partition. Will this be a problem, or is the warning there because it hasn't been tested enough but no problems found?
