Daniel Lindberg commented on ARTEMIS-807:
-----------------------------------------
Sorry, but I fail to understand this answer.
I got this exception on the original master during failback, not failover
(semantics I know, but just to be clear).
As far as I know, I cannot control when a failback happens. I simply start the
original master, the current master (original slave) will detect this, and
initiate a failback to the original master.
The initial failover happened without any issues as far as I can tell.
I don't see how I can 'wait' for the sync to be complete before initiating a
failback, since I'm not in control of this process.

> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker
> Affects Versions: 1.4.0
> Reporter: Daniel Lindberg
>
> We are running Artemis 1.4.0 on RHEL 7.2 using a master/slave setup using
> replication (one master and one slave). We did some failover/failback testing
> while having light load on the broker (15 messages/second). The failover
> worked without issues and the flow of messages was uninterupted.
> However on failback we got several exceptions, and eventually ended up in a
> state were both master and backup were down, resuling in our application
> failing.
> I haven't been able to track down the meaning of "File not opened code - 6",
> but this exception was repeated before we saw
> "ActiveMQIllegalStateException[errorType=ILLEGAL_STATE message=AMQ119026:
> Backup Server was not yet in sync with live]"
