I'm sorry to ask for help here, but I'm lost in the middle of nowhere ...
The context :
A PC hardware with an UEFI "BIOS" set to legacy boot only.
3 disks with 2 partitions each. The 3 first partitions are set in
software mirror (md0) and used for /boot (Ext4) .The second 3 partitions
are used as a software mirror and the resulting md1 is the sole PV of a
vg0 group onto which 8 logical volumes are set. This is used to run
Ubuntu 16.04.2 software (after many upgrades...). *

I've searched everything I can (but maybe the setup was so rock solid I
became lazy or unconscious) and tried to make again the initramfs with
So every leads or advice would be greatly appreciated. Please, refrain
to hit me hard on the face. I'm already mourning....
Many thanks in advance for your help !

in the LVM software. ... I switched to software raid and kept the 3
disks as I had them into the box.
