Booting a system installed on an iSCSI LUN with an additional network interface is not possible

[bugproxy]

Installer version: 20101020ubuntu451.10

Description/Reproduction:

System is installed with the following partitioning:
/boot on DASD
/ on an iSCSI LUN

Network:
1 OSA with VLAN as the regular network device for the system
2 OSAs with VLAN used for iSCSI. Those two OSAs were configured manually in a command shell during installation

After installation, the system is not bootable and the console is displaying the following error every second:
"iscsistart: cannot make a connection to 10.209.9.1:3260 (-1,101)"

When you brought up the networking manually, did you write out the updated /etc/network/interfaces and updated the target initramfs? By e.g. dropping back into shell at finish install step.

Because the installed system's /etc/network/interfaces will only have the netcfg configured network (the first one), but not any other networks brought up with ifup command.

Could you please extract and attache
1) the initramfs from the /boot DASD
2) /etc/network/interfaces from the / iSCSI LUN
3) /var/log/installer from the / iSCSI LUN

I edited the file /etc/network/interfaces but I wasn't able to update the initramfs because I don't know which tool to use for that. I was looking for update-initramfs but it doesn't seem to be installed.
I would appreciate if you could point me to the tool to use.

Are you talking about the file "initrd.img-4.4.0-77-generic"?

I will attach those files.

Sorry the file is larger than 10 MB and in case mirroring doesn't work, here's a link to the same file:

from the interactive shell of d-i, one should be able to do:

$ in-target update-initramfs -k all

To update initramfs, that essentially does: `chroot /target update-initramfs -k all`, but with extra logging and clean-up such that those commands end up in logs.

Downloaded the logs. Will inspect them.

And when I mean editing the /etc/network/interfaces, I mean /target/etc/network/interfaces at the end of the installation once netcfg purged and recreated it. Such that the installed system has correct interfaces.

Looking at the interfaces from the logs, it only has one vlan defined. Thus ence530.209 is missing from /target/etc/network/interfaces which needs to be adjusted when installer offers to "finish & reboot", by going back to the main menu and dropping into the shell, editing that file, and updating initramfs in-target.

Thank you for your hints. When "Finish and reboot" was displayed, I edited the /target/etc/network/interfaces file and afterwards executed "in-target update-initramfs -k all".

The system still doesn't boot although the interfaces are now listed in the "interfaces" file. I have uploaded the logs again.

Canonical, any update on this LP ?

[Dimitri John Ledkov (xnox)]

d-i only supports configuring only one network connection. This is unlikely to change, even for the 20.04 timeframe. The workarounds are 1) getting install media exported on the same network as the network attached hard drives 2) configuring additional network interfaces by-hand using d-i interactive shell.

Setting to 'In Progress' with the work on subiquity.

The new installer is now out, and supports configuring many networks at the same time.
