[Bug 1765765] Re: on nfsboot 18.04 bionic, internet addresses arn't resolve properly
Just to confirm that for me also, 18.04.2 vs 18.04.1 fixes this issue and the systemd resolver is correctly picking up the dns from the non- managed interface that resulted from the network boot with ip=dhcp. This is using the casper images with no modification - I still have to supply either 'toram' or 'systemd.mask=dev-hugepages.mount systemd.mask =dev-mqueue.mount systemd.mask=sys-fs-fuse-connections.mount systemd.mask=sys-kernel-config.mount systemd.mask=sys-kernel-debug.mount systemd.mask=tmp.mount' to dodge round the other issues, and note that the initrd has changed name from initrd.lz to initrd between .1 and .2 Just for the record, here my pxelinux configs, for a server at ...212 label bionic2toram kernel ubuntu-18.04.2-desktop-amd64/casper/vmlinuz append initrd=ubuntu-18.04.2-desktop-amd64/casper/initrd ip=dhcp toram boot=casper netboot=nfs nfsroot=192.168.10.212:/netboot/ubuntu-18.04.2-desktop-amd64 label bionic2 kernel ubuntu-18.04.2-desktop-amd64/casper/vmlinuz append initrd=ubuntu-18.04.2-desktop-amd64/casper/initrd ip=dhcp boot=casper netboot=nfs nfsroot=192.168.10.212:/netboot/ubuntu-18.04.2-desktop-amd64 systemd.mask=dev-hugepages.mount systemd.mask=dev-mqueue.mount systemd.mask=sys-fs-fuse-connections.mount systemd.mask=sys-kernel-config.mount systemd.mask=sys-kernel-debug.mount systemd.mask=tmp.mount -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765765 Title: on nfsboot 18.04 bionic, internet addresses arn't resolve properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1765765/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1765765] Re: on nfsboot 18.04 bionic, internet addresses arn't resolve properly
@Guillermo The OS shouldn't be trying to raise the interface as it's already configured during the boot process. You can't reconfigure the network interface while you're booting from the network :) You need to modify /etc/network/interfaces on your boot server to set the interface to manual. See step 5 under 'creating your NFS installation' on this page https://help.ubuntu.com/community/DisklessUbuntuHowto Related to this, I also set 'net.ifnames=0' in the kernel boot line so the network devices are always named ethX rather than hardware-specific names. That's personal preference though. @beta-tester Strange. Without specifying 'ip=dhcp' perhaps it was sometimes getting a bootp or rarp response without a DNS server settings? Just a guess. If 'ip=X' isn't set, it defaults to any autoconfig protocol. I'd suggest setting the ip option specifically to dhcp if that's what you expect it to use. https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765765 Title: on nfsboot 18.04 bionic, internet addresses arn't resolve properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1765765/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1765765] Re: on nfsboot 18.04 bionic, internet addresses arn't resolve properly
i never used ip=dhcp in the boot menu entries. strange i had those resolv issue with ubuntu 19.04 daily (pending) from 2019-02-14 for sure. now i tried again with ubuntu 19.04 daily (pending) from 2019-02-20, and now it seems to be not an issue. i also tried the other versions 18.10 and 18.04.2... there it is no issue with resolv anymore. the only thing i could notice now was, that resolving (ping google.de) takes a bit longer under 19.04 daily than under 18.10 / 18.04.2... or maybe it is only my mind. at the moment i can not reproduce my ony reported resolv issue. :/ pxe boot menu entries: LABEL ubuntu-daily-x64 MENU LABEL Ubuntu x64 Daily-Live KERNEL http://192.168.0.1/nfs/ubuntu-daily-x64/casper/vmlinuz INITRD http://192.168.0.1/nfs/ubuntu-daily-x64/casper/initrd APPEND nfsroot=192.168.0.1:/srv/nfs/ubuntu-daily-x64 ro netboot=nfs file=/cdrom/preseed/ubuntu.seed boot=casper -- debian-installer/language=de console-setup/layoutcode=de keyboard-configuration/layoutcode=de keyboard-configuration/variant=German TEXT HELP Boot to Ubuntu x64 Daily-Live User: ubuntu ENDTEXT LABEL ubuntu-x64 MENU LABEL Ubuntu x64 KERNEL http://192.168.0.1/nfs/ubuntu-x64/casper/vmlinuz INITRD http://192.168.0.1/nfs/ubuntu-x64/casper/initrd APPEND nfsroot=192.168.0.1:/srv/nfs/ubuntu-x64 ro netboot=nfs file=/cdrom/preseed/ubuntu.seed boot=casper systemd.mask=tmp.mount -- debian-installer/language=de console-setup/layoutcode=de keyboard-configuration/layoutcode=de keyboard-configuration/variant=German TEXT HELP Boot to Ubuntu x64 Live User: ubuntu ENDTEXT LABEL ubuntu-lts-x64 MENU LABEL Ubuntu LTS x64 KERNEL http://192.168.0.1/nfs/ubuntu-lts-x64/casper/vmlinuz INITRD http://192.168.0.1/nfs/ubuntu-lts-x64/casper/initrd APPEND nfsroot=192.168.0.1:/srv/nfs/ubuntu-lts-x64 ro netboot=nfs file=/cdrom/preseed/ubuntu.seed boot=casper systemd.mask=tmp.mount -- debian-installer/language=de console-setup/layoutcode=de keyboard-configuration/layoutcode=de keyboard-configuration/variant=German TEXT HELP Boot to Ubuntu LTS x64 Live User: ubuntu ENDTEXT -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765765 Title: on nfsboot 18.04 bionic, internet addresses arn't resolve properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1765765/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1765765] Re: on nfsboot 18.04 bionic, internet addresses arn't resolve properly
Hi Brian, No, I had to remove it since including it triggered some errors during boot. IIRC, one was "failed to raise network interfaces". I've tried with 18.04.2 and networking works, but there's only the raising network interfaces error. In both cases, gnome says that networking is "unmanaged". Does it make sense? Here's an extract from syslog under 18.04.2 with ip=dhcp: Feb 20 07:14:06 ubuntu avahi-daemon[924]: Failed to open /etc/resolv.conf: Invalid argument Feb 20 07:14:07 ubuntu NetworkManager[909]: [1550646847.4309] Error: failed to open /run/network/ifstate Feb 20 07:14:09 ubuntu ifup[1367]:Error: any valid prefix is expected rather than "dhcp/dhcp".
