Why does kickstart installation using md RAID1 fail to install bootloader on MBR even with correct partitioning?

Issue

• Why does kickstart installation using md RAID1 fail to install bootloader on MBR even with correct partitioning?
• The program.log complains that it cant find the md125 device, Which isn't specified in the kickstart file and when df is ran, it appears to be mounted correctly.
• Here is the partitioning.

ignoredisk --only-use=sda,sdb
bootloader --location=mbr --driveorder=sda,sdb --append="crashkernel=auto"
