[rabbitmq-discuss] Unable to delete vhost

[Ben Corlett]

I am having some issues when trying to delete a vhost. 

I'm using the latest version of rabbitmq 3.0.2 and my set up has two 
clusters (2 machines in each) with a federation for pub/sub messages. 

When trying to remove the vhost via the web interface I get the error :

Internal Server Error

The server encountered an error while processing this request:
{throw,
    {error,
        {{badmatch,
             {error_string,
                 "Validation failed\n\nname not recognised: undefined\n"}},
         [{rabbit_vhost,'-internal_delete/1-lc$^1/1-1-',2},
          {rabbit_vhost,internal_delete,1},
          {rabbit_vhost,'-delete/1-fun-0-',1},
          {mnesia_tm,apply_fun,3},
          {mnesia_tm,execute_transaction,5},
          {rabbit_misc,'-execute_mnesia_transaction/1-fun-0-',1},
          {worker_pool_worker,handle_call,3},
          {gen_server2,handle_msg,2}]}},
    [{rabbit_misc,execute_mnesia_transaction,1},
     {rabbit_mgmt_wm_vhost,delete_resource,2},
     {webmachine_resource,resource_call,3},
     {webmachine_resource,do,3},
     {webmachine_decision_core,resource_call,1},
     {webmachine_decision_core,decision,1},
     {webmachine_decision_core,handle_request,2},
     {rabbit_webmachine,'-makeloop/1-fun-0-',2}]}

When trying to remove the vhost from the command line I get something 
similar :

[rabbitmq at chi-sc-cget-m-rabbitmq-001 ~]$ rabbitmqctl delete_vhost 
v4e73843117c745bb8c1796c2a423b177
Deleting vhost "v4e73843117c745bb8c1796c2a423b177" ...
Error: {{badmatch,{error_string,"Validation failed\n\nname not recognised: 
undefined\n"}},
        [{rabbit_vhost,'-internal_delete/1-lc$^1/1-1-',2},
         {rabbit_vhost,internal_delete,1},
         {rabbit_vhost,'-delete/1-fun-0-',1},
         {mnesia_tm,apply_fun,3},
         {mnesia_tm,execute_transaction,5},
         {rabbit_misc,'-execute_mnesia_transaction/1-fun-0-',1},
         {worker_pool_worker,handle_call,3},
         {gen_server2,handle_msg,2}]}


Here are the commands to initially set up the vhost via a script (the hosts 
used here are vips which are load balanced across both nodes in the 
cluster) :
