Hi.
I'm about to try btrfs on an RAID0 md device (to be precise there will
be dm-crypt in between the md device and btrfs). If I used ext4 I
would set the stride and stripe_width extended options. Is there
anything similar I should be doing with mkfs.btrfs? Or maybe some
mount options beneficial

Hmmm. This makes the plaintext password visible in ps output.
It is probably better to pass this in by redirecting a file to stdin.

echo is built in, it will not show up in ps.

This is not directly an answer to your question, so far I haven't used a
special option like this with btrfs on my arrays although my
undertstanding is that it's not as important as with ext4.
That said, please read
