jbossews
Should be resolved for this case by https://github.com/openshift/origin-server/pull/2578. I should also note that these sorts of scaling tests (esp. with jboss cartridges) should be performed in a multi-node environment setup: As the scale-up events are executed in parallel, performing this scenario on a single node will rapidly eat resources and likely cause the operation to take a very long time and hit some timeout. In a clustered environment, the gears will be balanced across other physical nodes. Commit pushed to master at https://github.com/openshift/origin-server https://github.com/openshift/origin-server/commit/4e0393a67acc0ebc1b06578b31097353901761b8 Bug 965028: Increase connector timeout Check this bug in a multi-node environment and single node,the bug is not fixed. After setting min gear value as 3,and try to access the app's url,but it is redirected to /haproxy-status/ page,and two gears are down,can not access the down gear. Please refer to attachment.

Wei, You're experiencing a new general scaling bug: https://bugzilla.redhat.com/show_bug.cgi?id=966068 Which is resolved by: https://github.com/openshift/origin-server/pull/2600 Please re-test with the related bug's resolution in place. Thanks. Tested this bug on devenv_3262,it has been fixed for jbosseap: [redhat@localhost shell]$ rhc cartridge scale -a zqjbosseap -c jbosseap-6.0 --min 3 RESULT: jbosseap-6.0 (JBoss Enterprise Application Platform 6.0) -------------------------------------------------------- Scaling: x3 (minimum: 3, maximum: available) on small gears This gear costs an additional $0.03 per gear after the first 3 gears.
