raid10 - without stripe

raid10 - without stripe

[Roberto Spadim]

Hi guys, on old email, some one told me that was possible using raid10
with layouts, and without stripe
could i make a 2disks raid10 with layout?
i tried many commands but couldn´t work without stripe (disk grow
after each mdadm --create i made :/)
can anyone help? i want faster aligned reads (like raid0) but without
growing my disk size (i want only mirrors)

What actual commands did you try?  What exactly were the results?

i will try to get commands on bash history at production server, and post again

the array was two disks on raid10
expected result: fail a disk, the array continue
i tryed with far and near layout but couldn´t get mirror only 'stripe'
