Anthony Xu created CLOUDSTACK-6177:
--------------------------------------

             Summary: CS does XS master switch, which may cause weid XS behavior
                 Key: CLOUDSTACK-6177
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6177
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Hypervisor Controller
    Affects Versions: 4.3.0
         Environment: XS 6.2 with CS 4.3.0
            Reporter: Anthony Xu
            Priority: Critical
             Fix For: 4.4.0


When XS master is down, CS uses pool-emergency-transition-to-master and pool-recover-slaves API to choose a new master, this API is not safe, and should be only used in emergent situation, this API may cause XS use a little bit old(5 minutes old) version of XS DB, some of object may be missing in the old XS DB, which may cause weird behavior, you may not be able to start VM.
