Qpid: cluster-durable queues
Hi there,
I'm using qpid 0.8 and I'd like to use cluster durable queues.
Here is my test case:
1. Start a cluster that contains two nodes.
2. Create cluster durable queue: qpid-config add queue MyQueue
--cluster-durable
3. Kill one node by means of kill -9
4. Restart qpid on the second node
5. Expect cluster durable queue exists.
However there is no just created queue.
What I'm doing wrong?
Best Regards,
Sergey Zhemzhitsky

Carl, thanks a lot.
Could you provide me with links to read more about cman and quorum
manager?

Re: Qpid: cluster-durable queues
yes, that is correct.
One note is that if you use cman as a quorum manager, it will not let
you get
down to 1 node unless you set weights in your cman config.

Hi Gordon,
So, if a queue is --durable, no persistent messages will be lost.
If the queue is --durable and --cluster-durable all non persistent
messages will become persistent when only one node of the cluster remains.
Is my understanding of --cluster-durable option correct?

The --cluster-durable option only works for durable queues. Its function
is to make any transient *messages* on that queue persistent when the
cluster drops down to the last node.

The --cluster-durable option only works for durable queues. Its function
is to make any transient *messages* on that queue persistent when the
cluster drops down to the last node.

Hi Carl,
I want my queue to become durable when only one node in the cluster stands
alive. I believe this is what the --cluster-durable option is for.
