[Bug 1402763] Re: Multicast traffic not propating correctly over linux bridge
I enabled the multicast_querier using a udev rule for juju-br0; however physical host reboots are still resulting in impact lxc containers not re-joining the cluster; toggling the querier off/on again resolves the issue so I'm guessing some sort of race. ** Tags added: apparmor apport-collected ** Description changed: There's a lot of supposition in the title of this bug but its currently my best guess. In this deployment, I have a number of services running in LXC containers across multiple physical hosts; each service is clustered across three units, all on separate physical hosts, using corosync and pacemaker; when using multicast to support cluster communication, I occasionally see a container drop out of the cluster and use its isolation response (to shutdown all managed services); when using unicast I've not yet see this same problem. LXC containers are bridged to the main physical network using a linux bridge: eth0 - juju-br0 - vethXXX - | vethXXX | All MTU's are standard (1500).

Just to fill in a bit more detail, the physical hosts have multiple lxc containers (~3 each), any of which will be participating in a different multicast group; containers in the same group are spread across different physical hosts. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1402763 Title: Multicast traffic not propating correctly over linux bridge To manage notifications about this bug go to: https://bugs.launchpad.net/juju-core/+bug/1402763/+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 1402763] Re: Multicast traffic not propating correctly over linux bridge
I've done a bit more testing, and here are my observations: 1) rebooting a container internally/stop-start externally using lxc-* Works OK - container re-joins the corosync cluster just fine. 2) rebooting the physical host Fails - containers never re-join the corosync cluster and perform the configured isolation response which is to stop everything. That said, if I reconfigure the cluster to using a new multicast address, the cluster reforms OK. So it would appear that cross server multicast is not being restored on a physical server reboot; I guess this could be something todo with switch configuration as well. ** Tags added: smoosh -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1402763 Title: Multicast traffic not propating correctly over linux bridge To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1402763/+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
