when install dracut on ubuntu 16.04 LTS, Default kernel command line ip parameter value is wrong like ip=enp6s0f0:static and it can not be overwritten.

[gokhan27]

I installed dracut with apt # apt install dracut dracut-network then ı created initramfs image with #dracut -fv --logfile dracut.log but I see that ip parameter gets wrong value like ip=enp6s0f0:static. when I look at dracut.cmdline man, it can not get static value. when I reboot my server, dracut refuse and system halted. How can I overwrite dracut kernel command line parameters ?

Use

hostonly_cmdline="no"

in e.g. /etc/dracut.conf.d/my.conf and set your kernel command line parameter as you wish. For Fedora this is the default, btw. or call dracut with the --no-hostonly-cmdline option.

hi thanks, it is working :) But I have a problem. I want to delete vlan interface after network manager is up. Can I also ask a question about creating bonded vlan interface? My network interfaces file is below : ###################################################################################

This file describes the network interfaces available on your system

and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

auto lo iface lo inet loopback

auto enp6s0f0 iface enp6s0f0 inet manual bond-master bond0 mtu 9000

auto enp7s0f0 iface enp7s0f0 inet manual bond-master bond0 mtu 9000

auto bond0 iface bond0 inet manual mtu 9000 bond-mode 2 bond-miimon 100 bond-slaves none bond-downdelay 200 bond-updelay 200

auto bond0.20 iface bond0.20 inet manual vlan-raw-device bond0

auto br-iscsi iface br-iscsi inet static bridge_stp off bridge_waitport 0 bridge_fd 0 mtu 9000 bridge_ports bond0.20 address 10.1.20.161 netmask 255.255.255.0 gateway 10.1.20.1 dns-nameservers 10.1.31.3 ###################################################################################

How can I make above configuration with dracut ?

[haraldh]

https://mirrors.edge.kernel.org/pub/linux/utils/boot/dracut/dracut.html#_network

so something like:

bond=bond0:enp7s0f0,enp6s0f0:mode=2,miimon=100,downdelay=200,updelay=200:9000 vlan=bond0.20:bond0 bridge=br-iscsi:bond0.20 ip=10.1.20.161::10.1.20.161:255.255.255.0::br-iscsi:none:9000 nameserver=10.1.31.3 rd.iscsi.initiator=iqn.1993-08.org.debian:01:161 netroot=iscsi:10.1.20.11::::iqn.1992-08.com.netapp:sn.b3lab resume=UUID=e9c01031-f4b6-411a-944d-bc6dc214819b root=UUID=e096439f-c8a0-4aa9-ad47-7f2b32a1356f rootfstype=ext4

Hope that works.

I tried it and it didn't work. it entered dracut emergency mode and unfortunately I can not type anything with keyboard. do I need also add bootdev=br-iscsi ?

[haraldh]

no keyboard attached?

[gokhan27]

no, keyboard is attached and I also tried with virtual keyboard , but it didn't type any characters. it is like frozen

[haraldh]

is that a real machine? or a VM?

[gokhan27]

it is real machine Lenovo thinksystem SD530 server. I am connected to system on xclarity controller

[haraldh]

Hmm, without the rdsosreport.txt file and/or more debugging, I am helpless. Double check the settings. Maybe start with a more simple network setup, then advance to bridge and bonding.

[gokhan27]

on ubuntu manpage[1] bonding option is like bond=[::[:]]. it does not consist of mtu option. I will try it without mtu. http://manpages.ubuntu.com/manpages/xenial/man7/dracut.cmdline.7.html

[gokhan27]

@haraldh I tried with bond=bond0:enp6s0f0,enp7s0f0:mode=balance-xor vlan=bond0.30:bond0 bridge=bridge0:bond0.30 but it enters dracut shell. I see all interfaces are up except bridge interface. when I try manually add bridge on dracut shell, it says package not installed. do we need any drivers or modules for bridge-utils packet ?

[haraldh]

dracut uses ip instead of brctl.

-                brctl addbr $bridgename
-                brctl setfd $bridgename 0
+                ip link add name $bridgename type bridge
+                echo 0 > /sys/devices/virtual/net/$bridgename/bridge/forward_delay
[…]
-            brctl addif $bridgename $ethname
+            ip link set dev $ethname master $bridgename

[haraldh]

if you have console, may I ask you to boot with: rd.debug on the kernel command line and try to save and give me /run/initramfs/rdsosreport.txt

[gokhan27]

@haraldh I solved this problem adding "add_drivers+=" 8021q bonding bridge" to /etc/dracut.conf.d/10-debian.conf. then I run 'dracut --kernel-cmdline "bond=bond0:enp6s0f0,enp7s0f0:mode=balance-xor vlan=bond0.20:bond0 bridge=bridge1:bond0.20 ip=10.1.20.161::10.1.20.1:255.255.255.0::bridge1:off:9000 nameserver=10.1.34.5 rd.debug rd.shell rd.iscsi.initiator=iqn.1993-08.org.debian:01:161 netroot=iscsi:10.1.20.11::::iqn.1992-08.com.netapp:sn.b3lab resume=UUID=e9c01031-f4b6-411a-944d-bc6dc214819b root=UUID=8fec65b4-79e2-41c6-8aa5-8f946c210a90 rootfstype=ext4 rootflags=rw,relatime,errors=remount-ro,stripe=16,data=ordered" -fv /boot/initrd.img-4.15.0-29-generic' it is worked but now I have an other problem. If I run "systemctl restart networking", I have lost my connection. do I need also add these network definitions in /etc/network/interfaces file ?

[haraldh]

If I run "systemctl restart networking", I have lost my connection. do I need also add these network definitions in /etc/network/interfaces file ?

yes, you do

[haraldh]

Hmm, " 8021q bonding bridge " should be in the 90kernel-network-modules dracut module

[haraldh]

ah, maybe you were in hostonly mode and these modules were not loaded?

[gokhan27]

yes I see hostonly=yes in /etc/dracut.conf.d/10-debian.conf. But I didn't add it. this is default.
