Hi Ian/Tim, Trying to make sure I understand a correct steps. I'd like to re-install the whole system again. I do have a serial console connection. My plan is to have a /boot on a USB disk, with a 512bits data as passphrase from usb key. whole two disk SDA/SDB will be RAID1 with LUKS on top. Then LVM inside luks. Then, /root and /home.
From the boot log you shared I'm almost certain the /boot on usb is not needed for this to work, all you need to do to fix you current install is to change the single setting in flash to make init look in the correct place for the root disk.
The complex steps, ie finding and assembling the RAID, decrypting the drive and finding the VG inside have all worked you have a single problem left to solve which is the kernel commandline string.
Try on your serial console setting the following:setenv bootargs console=ttyS0,115200 root=/dev/VG01/root initrd=0xa00000,0x900000 ramdisk=34816
Then type bootNote the setenv line is one line, and I've assumed the LV for your root volume is called root.
I understand that I have to manage to change /dev/ram to /dev/??? (root in lvm?? on top of Luks).
This is a setting that is stored in the flash along with the kernel and initrd.
