[Bug 1003656] Re: bridge-utils/vlan udev hooks prevent execution of upstart hook, slowing down boot
Thank you Stéphane, in those log files I found the message: device br0 already exists; can't create bridge with the same name Failed to bring up br0. In /etc/network/interfaces below the br0 stance I had just to remove some lines: pre-up brctl addbr br0 pre-up brctl addif br0 eth1 pre-up brctl addif br0 tap0 ifconfig br0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255 These maybe were necessary in 10.04 lucid, when I set up the system first. So the update of bridge-utils made the config simpler in the end.

[Bug 1003656] Re: bridge-utils/vlan udev hooks prevent execution of upstart hook, slowing down boot
Please excuse the incomplete information; But I highly suspect it is releated, and maybe some bells ring with the experts. The week a system that I manage (xubuntu 12.04.1) failed to connect to the net on reboot. The br0 bridge interface does not get fully configured. There is nothing in syslog that points at a specific failure. The startup GUI shows waiting for network and waiting 60 more seconds for network before the greeter comes up. The bridge interface is used to bridge eth1 and OpenVPN tap0. It is solely configured from /etc/network/interfaces. I found that after tearing down the bridge completely, ifup br0 successfully completes. But it fails at boot time. bridge-utils may be the only package update between the last reboot, when thins still were fine (some 80 days ago). Next week I may collect more information (ifquery br0 # of the disfunctional bridge, brctl show, etc). -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to vlan in Ubuntu. https://bugs.launchpad.net/bugs/1003656 Title: bridge-utils/vlan udev hooks prevent execution of upstart hook, slowing down boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bridge-utils/+bug/1003656/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 1003656] Re: bridge-utils/vlan udev hooks prevent execution of upstart hook, slowing down boot
I have the same problem with quantal (image installed by MAAS) I've just created a bridge br0 in the interfaces file and now the system does not boot. it seems br0 is not going up if I do a brcrl addbr br0 everything works. I have not the bonding one, but seems to be the same error. The output of initctrl list shows: upstart-udev-bridge is runing upstart-socket-bridge is running cloud-init is running... it seems that cloud-init needs the interface up to continue but it never goes up... Also, I've modified the /etc/network/if-pre.up.d/bridge to show what interfaces are up when the system stalls: It shows that $IF_BRIDGE_PORTS goes empty, and is executed twice...

[Bug 1003656] Re: bridge-utils/vlan udev hooks prevent execution of upstart hook, slowing down boot
Gah, ignore my comment, perhaps the new version is working. The issue I see now seems to be that on the last reboot the MAC address of the bond has obtained the MAC of the other ethernet interface in the bond rather than the MAC address of eth0 (which is the one hard wired in my dhcpd config), meaning it's unable to obtain an IP address to to my dhcp server not knowing what address to give it. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to vlan in Ubuntu. https://bugs.launchpad.net/bugs/1003656 Title: bridge-utils/vlan udev hooks prevent execution of upstart hook, slowing down boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bridge-utils/+bug/1003656/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 1003656] Re: bridge-utils/vlan udev hooks prevent execution of upstart hook, slowing down boot
Rationale for not touching vlan is that it's never calling ifup and so shouldn't be able to cause a similar deadlock situation as bridge-utils. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to vlan in Ubuntu. https://bugs.launchpad.net/bugs/1003656 Title: bridge-utils/vlan udev hooks prevent execution of upstart hook, slowing down boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bridge-utils/+bug/1003656/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1003656] Re: bridge-utils/vlan udev hooks prevent execution of upstart hook, slowing down boot
I just spent a few minutes trying to figure out the ordering based on the scripts for Andrew's system, it's basically: - eth0 appears - triggers udev - triggers upstart - triggers ifup eth0 - triggers bonding - bond0 appears - triggers udev - triggers bridge-network-interface - triggers ifup br0 - br0 appears - triggers udev - triggers upstart - triggers ifup br0 = fails, already configured - dhclient br0 = fails as it's blocking and no interface in bond - triggers upstart - triggers ifup bond0 - eth0 is joined in the bond - eth1 appears - triggers udev - triggers upstart - triggers ifup eth1 - triggers bonding - eth1 is joined in the bond As you can see, it's relatively complex. The main problem as easily seen above is that udev being sequential, the ifup br0 will be called before the bond interface is fully setup and so will fail to acquire an IP as nothing's in the bond at this point. A possible way around the problem would be to only create the bridge from the udev hook but not actually call ifup, letting the upstart job take care of this. This would make the code similar to what vlan and ifenslave are currently doing where as far as I know we're not getting a similar deadlock. I have a system reproducing this bug, so I'll now be trying my workaround and re-read all the scripts once more to see if I missed something. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to vlan in Ubuntu. https://bugs.launchpad.net/bugs/1003656 Title: bridge-utils/vlan udev hooks prevent execution of upstart hook, slowing down boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bridge-utils/+bug/1003656/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
