[Bug 2013082] [NEW] EFI boot does not detect RAID.

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

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.
