[Bug 1936842] Re: agent cannot be up on LXD/Fan network on OpenStack OVN/geneve mtu=1442
I've removed ubuntu-fan. I'm working on a fix for this. What needs to happen is for the container NIC to use the MTU of the VXLAN accompanying the Fan bridge (which appears to be correctly offset from the underlay) rather than the bridge itself. ** No longer affects: ubuntu-fan (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1936842 Title: agent cannot be up on LXD/Fan network on OpenStack OVN/geneve mtu=1442 To manage notifications about this bug go to: https://bugs.launchpad.net/juju/+bug/1936842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Let me know what log / log level you want to see to compare. I'm attaching the machine log of the VM for the time being. ** Attachment added: "machine-0.log" https://bugs.launchpad.net/juju/+bug/1936842/+attachment/5533786/+files/machine-0.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1936842 Title: agent cannot be up on LXD/Fan network on OpenStack OVN/geneve mtu=1442 To manage notifications about this bug go to: https://bugs.launchpad.net/juju/+bug/1936842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hmm, I'm not sure where the difference comes from. With Juju 2.9.16 I still see mtu=1442 on VM NIC (expected) and mtu=1450 (bigger than underlying NIC) on fan-252 bridge. ubuntu@juju-913ba4-k8s-on-openstack-0:~$ brctl show bridge name bridge id STP enabled interfaces fan-252 8000.0653e0778a0a no ftun0 veth966fdd48 lxdbr0 8000.00163e2848ef no ubuntu@juju-913ba4-k8s-on-openstack-0:~$ ip l 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: ens3: mtu 1442 qdisc fq_codel state UP mode DEFAULT group default qlen 1000 link/ether fa:16:3e:27:18:ce brd ff:ff:ff:ff:ff:ff 3: fan-252: mtu 1450 qdisc noqueue state UP mode DEFAULT group default qlen 1000 link/ether 06:53:e0:77:8a:0a brd ff:ff:ff:ff:ff:ff 4: ftun0: mtu 1392 qdisc noqueue master fan-252 state UNKNOWN mode DEFAULT group default qlen 1000 link/ether 82:8a:c4:02:b5:77 brd ff:ff:ff:ff:ff:ff 5: lxdbr0: mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000 link/ether 00:16:3e:28:48:ef brd ff:ff:ff:ff:ff:ff 7: veth966fdd48@if6: mtu 1450 qdisc noqueue master fan-252 state UP mode DEFAULT group default qlen 1000 link/ether 06:53:e0:77:8a:0a brd ff:ff:ff:ff:ff:ff link-netnsid 0 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1936842 Title: agent cannot be up on LXD/Fan network on OpenStack OVN/geneve mtu=1442 To manage notifications about this bug go to: https://bugs.launchpad.net/juju/+bug/1936842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've added the ubuntu-fan package, as fanctl should accommodate the underlay MTU. There is a work-around for the Juju case, which I will look to implement. ** Also affects: ubuntu-fan (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1936842 Title: agent cannot be up on LXD/Fan network on OpenStack OVN/geneve mtu=1442 To manage notifications about this bug go to: https://bugs.launchpad.net/juju/+bug/1936842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
