[rabbitmq-discuss] rabbitmq 2.6.1 cluster failure recovery

[Alain Dazzi]

Hi,

I can't get my rabbitmq cluster to recover from a dead node. So
perhaps someone can help ...

node-1 (cumulonimbus)
Linux cumulonimbus 2.6.38-11-server #50-Ubuntu SMP Mon Sep 12 21:34:27
UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
ii  rabbitmq-server                       2.6.1-1
root at cumulonimbus:~# ls -1 /usr/lib/rabbitmq/lib/rabbitmq_server-2.6.1/plugins/

node-2 (nuage-informatique)
Linux nuage-informatique 2.6.38-11-generic #50-Ubuntu SMP Mon Sep 12
21:17:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
ii  rabbitmq-server                       2.6.1-1

1/ stop both servers and set-up same .erlang_cookie value; restart nodes

2/ on node1 I create a cluster
    rabbitmqctl stop_app
    rabbitmqctl reset
    rabbitmqctl cluster rabbit at nuage-informatique rabbit at cumulonimbus
Clustering node rabbit at cumulonimbus with ['rabbit at nuage-informatique',
                                          rabbit at cumulonimbus] ...
...done.

3/ This creates 2 disc nodes !!!

4/ run a test and pass data successfully

5/ restart node-2 (service rabbitmq-server stop)
service rabbitmq-server start ... fails with ...
root at nuage-informatique:~/Desktop# service rabbitmq-server start
Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_{log, _err}
rabbitmq-server.

At this point I have to re-install node-2 to recover.

Any idea why?

Thank you,

next I would like to test mirrored q but obviously this has to work first...
