Description of problem: rear fails while looking for efibootmgr and /boot/efi on ppc64/ppc64le which are not UEFI platforms. ~]# uname -i ppc64le ~]# rear -dv mkbackup ... ERROR: Cannot find required programs: efibootmgr ~]# rear -dv mkbackup ... ERROR: Could not find a matching kernel in /boot/efi/efi/redhat ! This is because it assumes the system is a UEFI platform if the /boot/efi directory merely exists, however, the new grub2-common package in RHEL 7.4 creates this empty directory on all systems, regardless of firmware type. A better check would be to look for the /sys/firmware/efi directory. ~]# rpm -q grub2-common grub2-common-2.02-0.64.el7.noarch ~]# rpm -ql grub2-common | grep efi /boot/efi/EFI/redhat ~]# less /usr/share/rear/prep/default/310_include_uefi_tools.sh # When /boot/efi is mounted we copy the UEFI binaries we might need # If noefi is set, we can ignore UEFI altogether if grep -qw 'noefi' /proc/cmdline; then return fi # next step, is checking /boot/efi directory (we need it) if [[ ! -d /boot/efi ]]; then # <--- BUG return # must be mounted fi REQUIRED_PROGS=( "${REQUIRED_PROGS[@]}" dosfsck efibootmgr ) ... ... Version-Release number of selected component (if applicable): rear-2.00-2.el7.ppc64le grub2-common-2.02-0.64.el7.noarch How reproducible: always Steps to Reproduce: 1. run rear on non-UEFI platforms with an empty /boot/efi directory Actual results: rear fails trying to do UEFI-ish things Expected results: rear does not do UEFI-ish things on non-UEFI platforms Additional info:
grub2-install had a similar problem, see bug 1443809
310_include_uefi_tools.sh is not the only file with this check: ~]# rpm -ql rear | xargs grep -l -- '-d /boot/efi' 2>/dev/null /usr/share/rear/output/ISO/Linux-ia64/400_create_local_efi_dir.sh /usr/share/rear/output/OBDR/Linux-ia64/400_create_local_efi_dir.sh /usr/share/rear/prep/default/310_include_uefi_tools.sh /usr/share/rear/prep/default/320_include_uefi_env.sh There may be more files that need updates to look for /sys/firmware/efi instead of /boot/efi.
This is almost certainly a duplicate of bz1479002, please try the test build provided there.
(In reply to Jeff Bastian from comment #0) > ~]# rear -dv mkbackup > ... > ERROR: Could not find a matching kernel in /boot/efi/efi/redhat ! It tries to find it there only if not found under /boot. If we remove the EFI part, it will just fail with an error message that it can not find a matching kernel under /boot. Where does one find the kernel on RS/6000 (or what machine is that)?
I was testing on a PowerNV (non-virt or bare metal) ppc64le system. The kernel is in the usual spot in /boot. ~]# ls /boot/vmlinuz* /boot/vmlinuz-0-rescue-719f435d87674d27a5e92dd3cdf9da93 /boot/vmlinuz-4.11.0.ppc64le Agreed, this is a dup of 1479002. Sorry for the noise! *** This bug has been marked as a duplicate of bug 1479002 ***
BTW, the test build for bug 1479002 works on my test system, thanks!
