The well known BIOSboot partition issue - Fedora does not install flawlessly on HDs larger 2 TB in Raid 1

[Peter Boy]

I am doing some test installations to contribute some of our internal documentation for
Fedora Server documentation. Thereby a problem with the BiOSboot partition occurred
again.


To set up the system with RAID 1, manual partitioning must be performed during
installation. I have created in the Anaconda GUI:
- BIOSboot Partition
- /boot as default partition and changed to raid 1
- /ROOT as LVM changed to raid 1 as well (and some additional LVs in that VG)


The installation aborted with the error message:

"The following error occurred while installing the boot loader. The system will not
be bootable. Do you want to ignore this and continue with the installation?
Boot loader install failed"


Anaconda creates BIOSboot only on the first hard disk, but then tries to install grub also
on the 2nd hard disk and fails because of the missing BIOSboot partition there. 

This was already discussed a long time ago and considered to create a BIOSboot partition
automatically when creating a GPT even without user action. However, concerns were raised
about this and the proposal was obviously not implemented. 

I have not found a way in the current Anaconda manual partition GUI to install BIOSboot on
the 2nd disk as well. My simple workaround was to boot a live system, set up GPT and
BIOSboot, shutdown, and then boot the Fedora Server installation image. 

The installation then went without a fuss. But is this the intended way? I suspect it
isn’t. I probably missed something.

Any hint appreciated.
