My best guess is that some other array is already using that bitmap file. cat /proc/mdstat should show you. There aren't many circumstances that can create Text file busy - either the file must be a binary that is being run, or a swap-file for which swapon has been run, or the file is a bitmap file for an md array (maybe there are some others, I cannot be bothered to grep just now).
