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).
