Description of problem:
When using DiskDruid to create a raid device on a system with 4 raid
devices already created and active, the new device is created as md0.
The new device shows in the disk druid listing as "Raid Device 4", but
when the device is actually created, it is created as md0. This leads
to the problem of having two arrays on the disk claiming to be md0,
and depending on the phase of the moon, the installer may trash the
contents of the previously existing md0 array.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install RH Linux on a software raid partition
2. reboot, and create 3 additional software raid partitions
3. Re-run the installation, creating a new software raid partition for
the second install. This should appear as "Raid Device 4"
4. Complete the installation, and note that there are now two md0 arrays.
Actual Results: Device is created as 'md0'
Expected Results: Device is created as 'md4'
Workaround: Create raid devices before starting the installation.
This should be better in newer code.
