             Summary: Post-boot transition to/from acting as a master or slave HC must be done with management op execution locked out
                 Key: WFCORE-1883
                 URL: https://issues.jboss.org/browse/WFCORE-1883
             Project: WildFly Core
          Issue Type: Task
          Components: Domain Management
            Reporter: Brian Stansberry


As part of WFCORE-338, a Candidate Domain Controller can shift between acting a master or acting as slave without requiring a reload or reboot.

However, after initial boot, a DCC can be handling management requests. Any transition between acting as a master or slave to the other role must ensure that in-process management requests are not disrupted and that no new management requests are able to access the management model or runtime services until the transition is complete. As a practical matter this likely means that the transition task(s) must acquire the exclusive management lock and hold it until the transition is complete.
