Just a note to say I've got the fix in testing. Even if it's not used, if it's still in the code it should at least work. Dangerous to have something saying it's worked when it hasn't.

Concerning that you are getting reports of it being orphaned though.

Now seeing this snippet I can explain the issue. So, during "orchestrateTakeVolumeSnapshot(work.getVolumeId(), work.getPolicyId(), work.getSnapshotId(), account, work.isQuiesceVm());" if an exception is thrown, it is caught and ignored by VolumeServiceImpl.takeSnapshot(VolumeInfo): @Override public SnapshotInfo takeSnapshot(VolumeInfo volume) { SnapshotInfo snapshot = null; try { snapshot = snapshotMgr.takeSnapshot(volume); } catch (Exception e) { s_logger.debug("Take snapshot: " + volume.getId() + " failed", e); } return snapshot; } So, "return new Pair<JobInfo.Status, String>(JobInfo.Status.SUCCEEDED, _jobMgr.marshallResultObject(work.getSnapshotId()));" will return JobInfo.Status.SUCCEEDED even when an exception was thrown. That said, I'm now getting a warning that VolumeApiServiceImpl.orchestrateTakeVolumeSnapshot(VmWorkTakeVolumeSnapshot) is never called, so I'm not sure if this method trace has changed since I reported the issue. (FYI, I've copied this info into the ticket as well) -Chris -- Chris Suich chris.su...@netapp.com<mailto:chris.su...@netapp.com> NetApp Software Engineer Data Center Platforms - Cloud Solutions Citrix, Cisco & Red Hat On Mar 18, 2014, at 9:11 AM, Alex Hitchins <alex.hitch...@shapeblue.com<mailto:alex.hitch...@shapeblue.com>> wrote: All, I'm looking at the following issue[0]. The reporter says in the second sentence the method is always returning success even when an exception occurs or otherwise fails. Looking at the code, if the inside call to orchestrateTakeVolumeSnapshot raises an exception, it should bubble up and not return the SUCCEEDED message surely? private Pair<JobInfo.Status, String> orchestrateTakeVolumeSnapshot(VmWorkTakeVolumeSnapshot work) throws Exception { Account account = _accountDao.findById(work.getAccountId()); orchestrateTakeVolumeSnapshot(work.getVolumeId(), work.getPolicyId(), work.getSnapshotId(), account, work.isQuiesceVm()); return new Pair<JobInfo.Status, String>(JobInfo.Status.SUCCEEDED, _jobMgr.marshallResultObject(work.getSnapshotId())); } [0] https://issues.apache.org/jira/browse/CLOUDSTACK-5825 Need Enterprise Grade Support for Apache CloudStack?
