It's happening when I first create the zone. I'll debug it further to tell
you exactly what its happening. But I don't understand how the following
code in DefaultEndpointSelector could be correct. If I have a zone, and I
delete/stop/crash the SSVM, and at the same time register a new template,
it seems the DownloadCommand will go to LocalHostEndPoint.
protected EndPoint findEndpointForImageStorage(DataStore store) {
Long dcId = null;
Scope storeScope = store.getScope();
if (storeScope.getScopeType() == ScopeType.ZONE) {
dcId = storeScope.getScopeId();
}
// find ssvm that can be used to download data to store. For
zone-wide
// image store, use SSVM for that zone. For region-wide store,
// we can arbitrarily pick one ssvm to do that task
List<HostVO> ssAHosts =
listUpAndConnectingSecondaryStorageVmHost(dcId);
if (ssAHosts == null || ssAHosts.isEmpty()) {
s_logger.info("No running ssvm is found, so command will be
sent to LocalHostEndPoint");
return LocalHostEndpoint.getEndpoint(); // use local host as
endpoint in
// case of no ssvm existing
}
Collections.shuffle(ssAHosts);
HostVO host = ssAHosts.get(0);
return RemoteHostEndPoint.getHypervisorHostEndPoint(host.getId(),
host.getPrivateIpAddress(),
host.getPublicIpAddress());
}
