While attempting to shutdown the engines in an HA cluster, the service manager process refuses to carry out the shutdown and ignores the stop script.
Users may see the following message in the service manager log:
INFO com.appian.komodo.admin.route.ManagerActionsRoute - Manager action 'shutdown-cluster' invoked
Additionally, Users may see that every "'shutdown-cluster' invoked" message is immediately followed by a "Cluster shutdown already in progress!" message. For example:
INFO com.appian.komodo.admin.route.ManagerActionsRoute - Manager action 'shutdown-cluster' invoked INFO com.appian.komodo.admin.route.ManagerActionsRoute - Cluster shutdown already in progress! INFO com.appian.komodo.admin.route.ManagerActionsRoute - Manager action 'shutdown-cluster' invoked INFO com.appian.komodo.admin.route.ManagerActionsRoute - Cluster shutdown already in progress!However, the shutdown does not proceed as expected.
Summary of symptoms:
These symptoms indicate that service manager was in a "cluster-stop" state prior to initiating the graceful shutdown. Typically, a user is trying to shutdown service manager on just one node in an HA configuration, but accidentally does a cluster stop which affects all other service managers in a cluster. Service manager could also get into this state if there was an issue with an intentional cluster shutdown, but only the engines are restarted and not service manager.
This issue can be remediated by restarting service manager by running the following:
<APPIAN_HOME>/services/stop.sh -p XXXXXXX -s manager
<APPIAN_HOME>/services/start.sh -p XXXXXXX -s all
If issues still occur, please contact Appian Support by creating a support case or emailing support@appian.com.
