noonedeadpunkadmin0: it feels like some networking issue between rabbit containers09:47
noonedeadpunkthe main issue here `Mnesia could not connect to any nodes.` which is stdout from rabbit itself09:47
admin0noonedeadpunk, i have done iperf ( got 9.3gbit) . tcpdumps .. i fail to find any issues09:47
noonedeadpunkand you would need to re-run rabbitmq_install with `-e rabbitmq_upgrade=true`09:47
noonedeadpunkI think it connects by hostname - have you checked that you have valid hosts file there?09:48
admin0yes .. from all 3 containers, i can ping all other 2 containers by its hostname09:49
admin0the ips and hostname checks out09:49
admin0i followed this also manually .. https://gist.github.com/niedbalski/69a72103adad4f0f9609a0857c9810a409:49
admin0but stuck in the same situation09:50
admin0i validated the .erlang secret using md5sum .. they are also in sync09:52
noonedeadpunkI'm wondering if smth is wrong with rabbitmq version you got. but we are bumping it to specific version to get the same one each run...09:52
admin0even re-formatted the controllers, and destroyed and re-initialized the whole setup completely to give it a new name/ip09:53
admin0and everything else works just fine .. (haproxy, galera) .. but always stuck in this rabbitmq09:53
admin0in the same time, while being stuck at this, i have setup the same exact ( copied the inventory ) to set it up in 4 differnt places and locations and they work fine09:54
admin0just this one specific build is puzzeling09:54
noonedeadpunkI think at this point you should have rabbitmq running on c1? can you telnet to it's port from c2 rabbit contianer?09:54
admin0i am able to telnet from c2 -> c109:58
admin0and also from c3 -> c109:58
admin0i get a connected msg09:58
noonedeadpunkWell, I'm not sure what to suggest... Maybe trying to do tcpdump while running `rabbitmqctl join_cluster "rabbit@c1-rabbit-mq-container-e1d2ff91"` or enable debug logs https://www.rabbitmq.com/logging.html#debug-logging10:01
admin0i did the tcpdump . it shows  the ports connecting and getting response .. ( only that part010:02
admin0i did not tried to dump that traffic10:02
noonedeadpunkit would be encrypted anyway10:14
noonedeadpunkI'm wondering about MTU?:)10:16
noonedeadpunkas all networking might work until it got encrypted because of mtu....10:17
admin0i just realized something10:29
admin0the baseip was set to 10.0.0.0/22 range .. while our lxdbr0 is at 10.0.3.0/24 which overlaps10:29
admin0changing all to 10.100 and retrying10:29
admin0but it would surprise me that on setup-infra, eveything else will work except rabbit10:30
