Red Hat Bugzilla – Bug 428108
service left untouched if restricted failover domain goes away
Last modified: 2018-10-19 20:24:03 EDT
Description of problem:
If a node is killed while a service is in the state "stopping", it remains in
this state even after the node comes back online. This only happens in the case
that the service is part of a restricted failover domain that prevents the
service being relocated elsewhere in the cluster; without this restriction the
service will be correctly re-started on another node.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Configure a cluster having a service that takes some time to start/stop (e.g.
the attached service script takes 30s for start/stop).
2. Configure the service as a member of a restricted failover domain that will
only allow the service to run on a single node.
3. While the service is running on that node, disable it and then kill power to
the node while the service is still shutting down.
Service stays in the state "stopping" forever even after the node is powered up
Service restarts automatically once the killed node is back online.
