Raid1+0: create stripe over two /dev/mdx on partition or not?
- by Chris
Given that I haven't found a way to define how a Raid10 is created with mdadm, i went the Raid1+0 solution.
How to display/define Mirror/Stripping pairs with mdadm
mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda1 /dev/sdf1
mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/sdg1 /dev/sdh1
mdadm --create /dev/md10 --level=0 --raid-devices=2 /dev/md0 /dev/md1
My question is about the stripe. For the mirror I create a primary partition over the full HD and set partition type to FD.
So, should I do the same for the Stripe? Create partition on /dev/md0 and /dev/md1 (primary over full 'HDD', set partition type correctly) and then do the stripe on the partition?
Is there a correct way here or are there any advantages/disadvantages to a solution?
Thank you
