Tomas Hofman commented on WFLY-7912:
------------------------------------
[~pferraro] I think this should be reopened. Changing from simple election policy to
random is working as you described, but changing from random back to simple is not:
{code}
[standalone@localhost:9990 /]
/subsystem=singleton/singleton-policy=default/election-policy=simple:add
{allow-resource-service-restart=true}
{
"outcome" => "failed",
"failure-description" => "WFLYCTL0158: Operation handler failed:
org.jboss.msc.service.DuplicateServiceException: Service
org.wildfly.clustering.singleton.policy.default.election-policy is already
registered",
"rolled-back" => true
}
{code}
The random-election-policy is not recognized as a required singleton sibling in
AddStepHandler and isn't removed.
Also, this approach doesn't go along with Web Console.
It's not possible to change election-policy of singleton-policy
---------------------------------------------------------------
Key: WFLY-7912
URL: https://issues.jboss.org/browse/WFLY-7912
Project: WildFly
Issue Type: Bug
Components: Clustering
Affects Versions: 10.1.0.Final
Reporter: Tomas Hofman
Assignee: Paul Ferraro
Attempt to change election policy:
{code}
[standalone@localhost:9990 /] batch
[standalone@localhost:9990 / #]
/subsystem=singleton/singleton-policy=default/election-policy=simple:remove
[standalone@localhost:9990 / #]
/subsystem=singleton/singleton-policy=default/election-policy=random:add
[standalone@localhost:9990 / #] run-batch
{code}
results in
{code}
The batch failed with the following error (you are remaining in the batch editing mode to
have a chance to correct the error):
WFLYCTL0062: Composite operation failed and was rolled back. Steps that failed:
Step: step-2
Operation: /subsystem=singleton/singleton-policy=default/election-policy=random:add
Failure: WFLYCTL0158: Operation handler failed:
org.jboss.msc.service.DuplicateServiceException: Service
org.wildfly.clustering.singleton.policy.default.election-policy is already registered
{code}
The bug seems to be introduced by
