Description William Caban 2019-05-29 19:06:34 UTC

Description of problem:
When using pxe boot in a bare-metal system with multiple interfaces, dracut ignores something like ip:eno2:dhcp and it tries DHCP on all interfaces

Version-Release number of selected component (if applicable):

openshift-install-linux-4.1.0-rc.5
rhcos-410.8.20190516.0-metal-bios.raw.gz


How reproducible:

100% of the time in bare-metal

Actual results:

It sends DHCP request over every interface and waits for a timeout. If the system has a lot of interfaces the NetworkManager-wait-online.service process fails and create a cascade failure during the bootstrap process.

Expected results:

To ignore all the other interfaces

> dracut ignores something like ip:eno2:dhcp

I assume you mean `ip=eno2:dhcp` ?

Comment 2 William Caban 2019-05-29 20:03:43 UTC

correct. like this:

  APPEND ip=eno2:dhcp ipv6.disable=1 rd.neednet=1 initrd=rhcos/rhcos-initramfs.img console=tty0 console=ttyS0 coreos.inst=yes coreos.inst.install_dev=sda coreos.inst.ignition_url=http://192.168.1.1:8000/bootstrap.ign coreos.inst.image_url=http://192.168.1.1:8000/metal/rhcos-410.8.20190516.0-metal-bios.raw.gz

Comment 3 Steve Milner 2019-05-30 13:15:58 UTC

Per the debug session yesterday it's been noted ip=eno2:dhcp is acting like it should. Closing this bug.
