Description of problem: rear mkbackup fails on UEFI system due to missing Version-Release number of selected component (if applicable): # rpm -q rear rear-2.00-2.el7.x86_64 How reproducible: Always Steps to Reproduce: 1. Use the following settings for /etc/rear/local.conf OUTPUT=ISO OUTPUT_URL=null BACKUP=NETFS BACKUP_URL=iso:///backup ISO_MAX_SIZE=4095 2.

Additional info:
This error message appears to be caused by the below snippet of code from /usr/share/rear/lib/uefi-functions.sh. $gmkimage $v -O x86_64-efi -c $TMP_DIR/mnt/EFI/BOOT/embedded_grub.cfg -o $TMP_DIR/mnt/EFI/BOOT/BOOTX64.efi -p "/EFI/BOOT" part_gpt part_msdos fat ext2 normal chain boot configfile linux linuxefi multiboot jfs iso9660 usb usbms usb_keyboard video udf ntfs all_video gzio efi_gop reboot search test echo btrfs StopIfError "Error occurred during $gmkimage of BOOTX64.efi" If a server is installed with 7.4 directly via uefi, it installs the grub2-pc-modules package instead of the grub2-efi-x64-modules package. If the server is installed with 7.2 or 7.3 directly then updated to 7.4 some appear to have installed the grub2-efi-x64-modules package, but some haven't. So based on the above code, for uefi there needs to be a required progs added for the grub2-efi-x64-modules package to prevent this error earlier on.
grub2-pc does depend on grub2-pc-modules, but grub2-efi does not depend on grub2-efi-modules, nor does grub2-efi-x64 depend on grub2-efi-x64-modules. Why this asymmetry?
For QE: sanity test was modified for testing this problem on UEFI system, see https://tcms.engineering.redhat.com/case/560858/
suggested workaround: install the grub2-efi-x64-modules package
*** Bug 1518217 has been marked as a duplicate of this bug. ***
I am afraid of forcing a dependency in spec as it would install it (the grub2-efi-x64-modules package) even on non-UEFI systems and I am not sure about the consequences. Therefore, I intend only to: - document the workaround - and add a more helpful error message, as suggested by Renaud (this would be a patch but probably a simple one).
I propose the following change: add a file usr/share/rear/output/ISO/Linux-i386/249_check_rhel_grub2_efi_package.sh with this content: ---------->8----------- # 249_check_rhel_grub2_efi_package.sh is_true $USING_UEFI_BOOTLOADER || return # empty or 0 means NO UEFI ( VERBOSE=1 test -r /usr/lib/grub/x86_64-efi/moddep.lst PrintIfError "WARNING: /usr/lib/grub/x86_64-efi/moddep.lst not found, grub2-mkimage will likely fail. Please install the grub2-efi-x64-modules package to fix this." ) ---------->8----------- Output of "rear mkrescue" with this change: WARNING: /usr/lib/grub/x86_64-efi/moddep.lst not found, grub2-mkimage will likely fail. Please install the grub2-efi-x64-modules package to fix this. ERROR: Error occurred during grub2-mkimage of BOOTX64.efi Aborting due to an error, check /var/log/rear/rear-localhost.log for details rmetrich, jentrena, are you happy with this?
I'm ok with that.
