Description of problem: create an scalalbe app and then scale-up this app,idle the gear created by scale-up, moving the gear to another node, check the gear's status after moving,it will be change to started. Version-Release number of selected component (if applicable): devenv_3246 How reproducible: always Steps to Reproduce: 1. set multi-node env (node a and node b) 2. create an scalable app 3. scale-up this app 4. change all of gears to idle status 5. moving the gear to another node 6. check the gear's status after moving Actual results: after step 4: [zqzhao@dhcp-13-222 non_scalable]$ rhc app show zqpy26s -g ID State Cartridges Size SSH URL -------------------------------- ----- ---------------------- ----- ------------------------------------------------------------------------------------- 0c75624ac12711e28ae512313d2d5271 idle python-2.6 haproxy-1.4 small 0c75624ac12711e28ae512313d2d5271.rhcloud.com 5f67b7bec12711e28ae512313d2d5271 idle python-2.6 haproxy-1.4 small 5f67b7bec12711e28ae512313d2d5271.rhcloud.com after step 6.

We have 2 problems during gear move: - 'idle' gear state will change to 'started'. - oo-idler will say gear 'idle' for the head/ha-proxy gear although ha-proxy process is still running on the gear. Problem: cond-reload functionality is missing in V2 HA-proxy cart. When app connections are executed, V1 ha-proxy is doing cond-reload but in V2 ha-proxy is doing restart. Only when the app state is 'started', we should do either reload/restart of the ha-proxy service. Look at restart() vs reload() vs cond_reload() methods in /usr/libexec/openshift/cartridges/haproxy-1.4/info/bin/app_ctl.sh
