Prev: tool to extract media from binary blobs?

Hi everybody,

I'm building a RAID array (with mdadm) that will contain few thousands of
big files (some MB to some GB).
For the filesystem (ext4), I'm going to use -stride and -stripe-width (for
the RAID), and "-T largefile" to optimize the space.

But: if I got it right, stride = chunk size / block size (e.g.: chunk = 128
kiB, block = 4 kiB -> stride = 32). And, looking at /etc/mke2fs.conf, I see
that for "largefile" blocksize is -1 ... so, how do I compute the stride?

Any suggestion is welcome :)
