Software RAID (0+1)

Hi!
A couple of months ago a disk failed in our JBOD cabinett and I have finally got a new disk to replace it with. It was a RAID 0 so we have to create and configure the whole thing again. First we thought of RAID 1+0 but it seems you can't do this with LVM. If you read my last thread, you can see I'm quite new at this so I just need some pointers to where I should begin. Maybe an howto-guide or where I could find some helpful documentation. We got 15 disks where 14 should be used in the RAID and then have 1 spare. So it will be two stripe set with 7 disks each and then mirror them somehow.

Really could use some help or pointers on where to begin.

Regards,
Hoff
