How do you delete a queue when the home node is permanently down?

[Brian Locke]

We are unable to use a queue because it's home node is on a server that used to be in the cluster and is no longer in existence.

How do you remove that queue or re-assign the home node so that it can be used again?

"home node 'rabbit@RABBITMQ5' of durable queue 's.03333003333.c.69' in vhost 'scanner_msgs' is down or inaccessible"

Thanks!

Brian,

Try this trick with policies:

H aving a rabbitmqctl command that does it would be helpful. We will consider
it but likely for a 3.6.x release.

Thanks for that. I also dug further back and found an 'eval' command to try.

Neither of these commands work. Not sure if it's my installation or not. 

RabbitMQ 3.54 , Erl 17.5, Windows Server 2012 R2

executing: rabbitmqctl set_policy --apply-to queues --priority 100 s.0024e00a18b9.c.69 '^s.0024e00a18b9.c.69$' '{"ha-mode":"nodes", "ha-params":["rabbit@RABBITMQ1"]}'

returns: Error: function_clause

executing: rabbitmqctl eval 'rabbit_amqqueue:internal_delete({resource,<<"scanner_msgs">>,queue,<<"s.0024e00a18b9.c.69">>}).'

returns: << was unexpected at this time.

I'll keep digging but please let me know if I've typoed something.

Thanks!

It's Windows shell escaping. Try double outer quotes instead of single ones.

[Brian Locke]

Boy, talking about not seeing the 'forest for the trees'. I totally forgot that windows requires escaped quotes.

For future reference for Windows users, here's what the working command looks like:

rabbitmqctl eval "rabbit_amqqueue:internal_delete({resource,<<""scanner_msgs"">>,queue,<<""s.0024e00a18b9.c.69"">>})."

Thanks Michael!
