[PVE-User] sbin/unconfigured.sh

[Steve]

In version 3.2 ISO there was this script to start an install.
This file is not in recent versions.
Is there an equivalent way to start an install with v4.4 or any other
recent version?
Thanks
Steve

Don't know what your situation is but there is a wiki page [1] that describes the installation of Proxmox on top of an
existing Debian.

Thanks for the quick reply.
I am booting from the ISO file itself which is on a multiboot USB drive.
In previous versions, you could boot to the shell, mount the ISO as /mnt
and then start the install by running unconfigured.sh.

So basically, if I boot to the shell, how can I start the install from the
contents of the CD/ISO.

you need to mount the contained squashfs files in the right order on the
right places, make an overlayfs and then bind mount the iso into that.
then you can chroot and run the unconfigured.sh script. basically do all
the steps that the initrd contained on the iso does ;)

[Steve]

Thanks
I tried that.
I made a new .sh from the portion of the initrd that mounts all the
squashfs files and runs unconfigured.sh.
It seems to almost work, but it gets to Detecting network settings... done
and then says
\nInstallation aborted - unable to continue

any ideas why?

boot it with "proxdebug" as part of the kernel cmdline and examine the
logs. you can also manually run "xinit" in the debug shell to restart
the installer from the debug shell.

[Steve]

I tried proxdebug. No extra messages are generated after the network has
initialised.
There is no log in /tmp folder ? Has the log moved?

How do I run xinit? Where is it?
Do you mean init? If I run this it says must be run as PID 1 - how can I
fix this (sorry, I am not a linux guru!)

just type "xinit" in the debug shell. but if you are not comfortable
with this kind of debugging, you might be better off just (temporarily)
"sacrificing" a thumb drive for the PVE installer instead of trying to
get this non-standard way to boot it to work ;)

I hope to fix the initrd during the 5.x release cycleto to allow booting
in some kind of loopback mode, but it's a low priority item on my todo
list..

[Steve]

If I type xinit it says /bin/sh: xinit: not found

I am the author of easy2boot which is a USB multiboot tool to allow people
to boot from 100's of different ISOs (or images) all from one USB stick.
I have been asked by a user to get proxmox 4 working.
3.2 works because I can run the unconfigured.sh from the command line

http://rmprepusb.blogspot.co.uk/2014/03/add-proxmox-isos-to-easy2boot.html
http://www.easy2boot.com

I tried setting proxdebug and root=/dev/sdb1 or lvm2root=/dev/sdb1 to get
it to mount the FAT32 partition to /mnt. I do not need to manually use any
mount commands, it just automatically runs init but this causes an early
error message of
mount: mounting /dev/sdb1 on /mnt failed: Invalid argument
but if I use the mount command I can see that /mnt is present as a vfat
/dev/sdb1
If I press CTRL+D to continue, it fails in the exact same place with
Installation aborted - unable to continue.
Note that this is not using my script at all, just the original init script
- I have not broken into the boot process because it picks up the lvm2root
parameter.

I am so *near*, yet I just cannot get the unconfigured.sh script to run in
this way...

thanks for your help.

I just did a quick test run using Grub:

loopback test PATHTOISO
linux (test)/boot/linux26 proxdebug ramdisk_size=16777216 rw
initrd (test)/boot/initrd.img
boot

drops me into the initrd debug shell

if I do the following (major/minor depend on your disk configuration,
check /sys/class/block/XXX/dev where XXX is your usb partition where
the iso is)

mknod /tmp/usbdev b MAJOR MINOR
mkdir /tmp/usbmnt
mount /tmp/usbdev /tmp/usbmnt
mount /tmp/usbmnt/PATHTOISO /mnt

followed by lines 294ff of the init script launch the graphical
installer (although the resolution is messed up - probably because I did
not bother to change any of the graphic stuff in Grub), and I am able to
complete the installation..

so I think it must be something in your environment / setup.

(note that there are TWO debug shells, one in the initrd with very
limited commands, and one in the installer environment with access to a
lot more tools - a quick test is to run something like "lsblk", since
that only exists in the latter environment ;). maybe your switch to the
installer environment did not work, and you are still in the initrd
shell? that would explain why you can't execute "xinit")

[Steve]

I just found a way to get it to work by modifying the grub menu and add
lvm2root=/dev/sdX4

where sdX4 is a partition on the USB drive which points directly to the ISO
file.
So I am booting from the ISO (mapped to the BIOS device (0xff) in grub4dos)
which boots to the grub2 menu and then I add the lvm2root parameter.

The strange thing is that if I boot from a FAT32 flat-file system and have
the ISO mapped to a partition in exactly the same way, the init script
fails.

I think the problem is with grub4dos.

If I use this menu from a FAT32 USB drive

title ProxMox lvm2root=sda1
kernel /boot/linux26 ro ramdisk_size=16777216 lvm2root=/dev/sda1 rw quiet
splash=silent
initrd /boot/initrd.img

then it does not work and I get the Installation aborted message

but if I use the same menu in grub2 from the same drive,

menuentry 'Install Proxmox VE sda1' --class debian --class gnu-linux
--class gnu --class os {
linux /boot/linux26 ro ramdisk_size=16777216 lvm2root=/dev/sda1 rw quiet
splash=silent
initrd /boot/initrd.img
}

then it works and loads the installer GUI.

I also note that it does not change to 1024x768 when booting via grub4dos,
so I added

vga=791

and now it works!!!

One last hurdle!

instead of /dev/sda1 I want to use /dev/disk/by-uuid/XXXXXXX because I
don't know how many disks there are in the system

but it does not work - I presume that /dev/disk/by-uuid does not yet exist
at the time the init script is running?

Is there any other way to reference the partition? I am guessing that
by-label will not work either?...

P.S.
As an experiment, I even inserted a dd'd flash drive containing the proxmox
ISO (which works if I boot to it) and then booted from my multiboot USB
drive to the shell and then mounted /mnt as the flash drive
mount /dev/sdc /mnt

then I ran the modified script.
I gave the same fail message.
So that seems to indicate that something is wrong with the script or
environment when I run the script?

The script I run starts with
if [ -f /mnt/pve-installer.squashfs ]; then
echo this is a Proxmox VE installation CD

if ! mount -t squashfs -o ro,loop /mnt/pve-base.squashfs
/mnt/.pve-base; then
debugsh_err_reboot "mount pve-base.squashfs failed"
fi

any ideas what is not set up before this?

contents of the CD/ISO.

you need to mount the contained squashfs files in the right order on the
right places, make an overlayfs and then bind mount the iso into that.
then you can chroot and run the unconfigured.sh script. basically do all
the steps that the initrd contained on the iso does ;)
