What were you trying to do that didn't work?
When the system to be converted is a UEFI system with the EFI partition on a software raid, the conversion fails in pre-checks:
# efibootmgr -v

Error:
(ERROR) EFI::BOOTLOADER_ERROR - Bootloader error detected
Description: An unknown bootloader error occurred, please look at the diagnosis for more information.
Diagnosis: The '/dev/md125' device has no PART_ENTRY_NUMBER
Remediations: N/A
The reason for this is grub.get_efi_partition() in /usr/lib/python2.7/site-packages/convert2rhel/actions/system_checks/efi.py returns the virtual device /dev/md125, instead of each device making the Raid (which is in 1.0 metadata format), i.e. /dev/vda2 and /dev/vdb2 (multi-valued as well).
The code clearly doesn't handle UEFI + Software Raid.
Please implement a wiser check.
Additionally you will have to implement a wiser implementation of EFI Boot Manager entries replacement as well, function _add_rhel_boot_entry() in /usr/lib/python2.7/site-packages/convert2rhel/grub.py, this part is also failing, since each individual device must be added to boot loader.
Please provide the package NVR for which bug is seen:
convert2rhel-2.0.1-1.el7.noarch
Probably RHEL8 convert2rhel but didn't check
How reproducible:
Always
Steps to reproduce
- Install a VM in UEFI mode with Software Raid
See above for the minimal disk layout. - Try converting it
Expected results
Success
Actual results
Failure in pre-checks.
When disabling the pre-check, failure writing the new bootloader entry:
