18 Hi,

20 Never tried this myself but I think you should have no problems with
21 mdadm. AFAIK JBOD is called "linear mode" in kernel and mdadm terms.
22 Given that you have compiled the necessary modules you'll have to do
23 something like:
24
25 mdadm --create /dev/md0 --level=linear --raid-devices=2 /dev/sd{a,b}1
26 mdadm --create /dev/md0 --level=mirror --raid-devices=2 /dev/{md0,sdc}
