---------------------------------------------

             Summary: Unable to deployVm from template when the management server was restarted in the middle of Secondary to Primary storage template download
                 Key: CLOUDSTACK-3249
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-3249
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Management Server
    Affects Versions: 4.2.0
            Reporter: Alena Prokharchyk
            Priority: Critical
             Fix For: 4.2.0


Steps to reproduce:

1) Have 1 cluster, 1 primary storage in cluster.
2) Call deployVm command.
3) After the command to copy template from secondary to primary storage, was sent over to the hypervisor, restart the MS.
4) After the MS is restarted, try to deploy new vm from the same template. The job gets stuck, and in the MS you see messages like:

"Multiple threads are trying to copy template to primary storage, current thread should just wait"

The current thread will wait for eternity. The problem is, on the step #3 the record was created in template_spool_ref table, and the record stays there in Creating state even after the MS restarts. So when new deployVm is called, it checks the table, sees the record and thinks that some other thread does the download, while that thread was gone with the management server restart.
