Subject Re: Sending to LocalHostEndpoint, Is there any resolution for this?
Date Thu, 31 Oct 2013 17:18:58 GMT
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());
    }
