I just tested again. It worked the 1st iteration, but 2nd iteration, the
backup-f is waiting to be paired with primary.
1. start all broker instances
2. kill primary-f
3. check backup-f is active
4. start primary-f
5. check primary-f is the backup of backup-f
6. kill backup-f
7. check primary-f is active
8. start backup-f
9. backup-f is the backup of primary-f
10. kill primary-f
11. backup-f is active.
12. start primary-f
13. primary-f is backup of backup-f.
14. kill backup-f
15. primary-f is active
16. start backup-f
17. waiting to be paired with primary server.
However; if I changed the back server config to have
<allow-failback>true</allow-failback>, it always work.
Just want to be clear the configuration. I copy and paste the 3 cluster
broker.xml below:
Cluster 1

Hi Rahman,
I'm not able to reproduce this issue with following steps:
1. create broker instances
./bin/artemis create primary-f --user admin --password admin
--require-login --clustered --cluster-password artemis --cluster-user
artemis --replicated --host localhost --port-offset 0
./bin/artemis create backup-f --user admin --password admin
--require-login --clustered --cluster-password artemis --cluster-user
artemis --replicated --host localhost --port-offset 1 --backup
./bin/artemis create primary-b --user admin --password admin
--require-login --clustered --cluster-password artemis --cluster-user
artemis --replicated --host localhost --port-offset 2
./bin/artemis create backup-b --user admin --password admin
--require-login --clustered --cluster-password artemis --cluster-user
artemis --replicated --host localhost --port-offset 3 --backup
./bin/artemis create primary-t --user admin --password admin
--require-login --clustered --cluster-password artemis --cluster-user
artemis --replicated --host localhost --port-offset 4
./bin/artemis create backup-t --user admin --password admin
--require-login --clustered --cluster-password artemis --cluster-user
artemis --replicated --host localhost --port-offset 5 --backup
2. edit broker.xml files
3. start all broker instances
4. kill primary-f
5. check backup-f is active
6. start primary-f
7. check primary-f is the backup of backup-f
8. kill backup-f
9. check primary-f is active
10. start backup-f
11. check backup-f is the backup of primary-f
Could you double-check those steps?
Regards,
Domenico
