Hi Team ,

We have a 2 node cluster with RMQ 3.13.1 and Erlang 26.2.2 .

We have by default, the vhost has quorum queues and around 5k pending messages in total all queues

Today , when we reboot one node , we see below behaviour :

1. Unable to publish message to cluster , on to a queue whose leader node is down . Ideally , cluster should take message and synchronize to both the nodes once all the nodes are up

2. We saw some message loss during the node restart , Is it general behaviour for a quorum queue to loose messages when node is restarted ?

3. How should we ensure High availability of messages / persistence even in case of node down in this version of RMQ and Quorum queues.

Thanks,

Abhishek

Hi,

start from using at least 3 nodes for your cluster https://www.rabbitmq.com/docs/clustering#node-count and see how it goes.

Hi Vilius,

You mean to say , if we are using Quorum queues in our cluster , that it should be always of 3 node cluster ??

What is the issue , if we have 2 node cluster ?? Ideally if the messages get replicated to other node with Quorum queues , then there should not be any message failures at least during node restarts.

Could you please advise on the same.

Thanks,

Abhishek
