[rabbitmq-discuss] Unable to cluster..

Tue May 15 05:28:08 BST 2012

Hello Emilie et all,

OK, so I am now getting a different, cryptic error when trying to cluster:

[root at rabbit-test2 ~]# rabbitmqctl cluster rabbit at rabbit-test1
Clustering node 'rabbit at rabbit-test2' with ['rabbit at rabbit-test1'] ...
Error: {unable_to_join_cluster,
           ['rabbit at rabbit-test1'],
           {aborted,
               {function_clause,
                   [{mnesia_schema,cs2list,
                        [{cstruct,schema,set,[],
                             ['rabbit at rabbit-test1'],
                             [],0,read_write,false,[],[],false,schema,
                             [table,cstruct],
                             [],[],
                             {{1336,612893,960781},'rabbit at rabbit-test1'},
                             {{6,0},
                              {'rabbit at rabbit-test1
',{1337,33903,595724}}}}]},
                    {mnesia_schema,do_merge_schema,0},
                    {mnesia_tm,apply_fun,3},
                    {mnesia_tm,execute_transaction,5},
                    {mnesia_schema,schema_coordinator,3}]}}}

And status now passes correctly as well:

[root at rabbit-test2 ~]# !90
rabbitmqctl -n rabbit at rabbit-test1 status
Status of node 'rabbit at rabbit-test1' ...

          {atom_used,1134812},
          {binary,82912},
          {code,11341457},
          {ets,783296}]},

...done.

Thanks,
