rear recover 后,/boot/grub2/grubenv 丢失

Solution In Progress - Updated -

Issue

  • rear recover 后,/boot/grub2/grubenv丢失。
  • 尽管系统可以在没有/boot/grub2/grubenv的情况下启动,但以下错误经常在消息文件中输出。
systemd[118744]: Starting Mark boot as successful...
grub2-set-bootflag[119441]: Error canonicalizing /boot/grub2/grubenv filename: No such file or directory
systemd[118744]: grub-boot-success.service: Main process exited, code=exited, status=1/FAILURE
systemd[118744]: grub-boot-success.service: Failed with result 'exit-code'.
systemd[118744]: Failed to start Mark boot as successful.
  • 安装新内核,/boot/efi/EFI/redhat/grubenv未被更新,因此系统默认总是启动到旧内核。即使grubby --default-kernel显示新内核是默认内核。
  • ReaR 2.4 没有这个问题。

Environment

  • Red Hat Enterprise Linux 8
  • Red Hat Enterprise Linux 9
  • ReaR 2.6
