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 boot
Note 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.
