Public bug reported: I'll copy from this report, please notice that I'm NOT the original reporter!:
https://bugs.launchpad.net/kolla-ansible/+bug/2033980/comments/8 Before cleaning the PID file, I did take a look at the config of radvd: ``` $ cat /var/lib/neutron/ra/aee91f41-1945-40b4-b72f-8be2eb369b44.radvd.conf interface qr-caa16d7e-26 { AdvSendAdvert on; MinRtrAdvInterval 30; MaxRtrAdvInterval 100; AdvLinkMTU 1450; RDNSS 2a02:74a0:x:0::53 10.40.3.53 2a02:74a0:x:0::54 {}; prefix 2a02:74a0:x:y::/64 { AdvOnLink on; AdvAutonomous on; }; route fe80::a9fe:a9fe/128 { }; }; ``` We've been configuring the router with terraform, assigning the ipv4 resolvers to the IPv4 subnet and the IPv6 resolvers to the IPv6 subnet. After deleting the router, adjusting the subnets (no resolvers on v4, only ipv6 resolvers on ipv6), and recreating the router, radvd is now active and everything's fine. It seems that due to misconfiguration (and incomplete template parsing), IPv4 nameservers ended up in the config of radvd, which failed to start. Neutron was then unable to clean up the pidfile, thus failing to start radvd again. ** Affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
