I'm struggling with the manual configuration of a RAID1 + RAID10. I'm trying the procedure on a VM (VirtualBox 5.0.14 r105127) on OSX 11.10.3.

The strategy I took is:

The complete set of commands I did is available here.

  • Install first centos on the first disk /dev/sda.
  • Then migrate all the files to the raid arrays cp -a mnt/old* mnt/new (even included the /boot/efi partition)
  • Chrooting into the RAID system
  • Edit /etc/fstab with the corrent mappings
  • Edit /etc/default/grub adding rd.auto=1 rd.lvm=[...] rd.md.uuid=[...] with the correct values.
  • Rebuilding initramfs dracut --mdadmconfig --fstab --add "mdraid" --add-drivers "raid1 raid10"
  • Rebuilding grub.cfg grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg
  • Adding the new entries into EFI NVRAM for i in b c d; do efibootmgr --create --disk /dev/sd$i --label "CentOS Backup - /dev/sd$i" --load "\\EFI\\centos\\grub.efi"; done
  • Getting Boot Failed for all the entries.

What Am I missing here?


Details

Few details on the current status, commands issued from the /dev/sda system
