Having an odd problem with my raid 1 array after upgrade to F19.
Upgraded using fedup from 18 to 19. Did not have any problems
with the upgrade itself but since my raid 1 array is stuck read only after
each reboot.

This is a bios intel raid set-up I have been using for a little over three years.
So I know it has been quite stable.

The os is installed on the raid 0 array. I use the raid 1 for things I would
rather not lose.

I have to re-write out the partition table using fdisk after each reboot
to get the array to go active.
