Title:
  EFI boot does not detect RAID.

Status in grub2 package in Ubuntu:
  New

Bug description:
  I installed ubuntu 22.04.2 in a raids structure.
  The grub.cfg files seem fine.

  Content of EFI grub.cfg is

  search.fs_uuid b9c1881f-a0b5-4fe3-b5ea-eb3d4567cfec root mduuid/d9442342aaf72e055793a60e5ed333e4 
  set prefix=($root)'/boot/grub'
  configfile $prefix/grub.cfg

  
  The boot crashes.
  But a can do this command
  mdadm --examine --scan
  The response is
  mdadm no device listed in /etc/mdadm/mdadm.conf

  
  I suspect that the EFI part does not know how to correctly assemble the RAID because during the 

  I don't know how to transmit the crash at this precise moment.

  The workaround found is to make a standard EXT4 partition dedicated to
  booting. However, that seems abnormal to me then the EFI part proposes
  to boot directly on the RAID if it is not possible.

  Thank you for doing what is necessary to have something coherent.
  Good day.
