Just an update on this, it appears that dmraid is calculating the RAID0 cylinders differently from the previous version.
And as such any partition going right to the end causes it confusion.

Basically on my first RAID set the smallest drive is 9729 cylinders, so with a RAID0 array 2x9729 is 19458, this is the number of cylinders that dmraid-rc14 calculates.
dmraid-rc15 on the other hand is a little bad at maths and calculates it to be 19457 cylinders.
I was thinking that the cylinder count should be even given a RAID0 should be symmetrical to function properly.

My partitions go all the way to the end of the drive and that is why my extended partition didn't load, to solve this I spent ages resizing my partitions, the worst was my large drive as its completely NTFS and it had all sorts of issues.

So now I am running Jaunty with all my drives loaded, but the bug still remains with anyone else who migrates and has used all of of the RAID0 partition space.

Hope this helps
