It may not do this at all +if the volume is mounted or in-use, or may not by the time we time out +if lots of dirty data needs flushing. Right now, we let the failure +exception bubble up to our caller and we log a nasty stack trace, which +doesn't really convey the reason (and that it's an expected and +reasonable thing to happen). + +Thus, this patch catches that, logs the situation at warning level and +avoids the trace. + +Change-Id: I3800b466a50b1e5f5d1e8c8a963d9a6258af67ee +Closes-Bug: #1750680 +(cherry picked from commit b16c0f10539a6c6b547a70a41c75ef723fc618ce) +(cherry picked from commit 81992142f657a3d71600182935f06efe5f8e8e86) +--- + +diff --git a/nova/virt/block_device.py b/nova/virt/block_device.py +index 74c26ce..aa1a3ee 100644 +--- a/nova/virt/block_device.py ++++ b/nova/virt/block_device.py +@@ -281,6 +281,10 @@ + '%(mp)s : %(err)s', + {'volume_id': volume_id, 'mp': mp, + 'err': err}, instance=instance) ++ except exception.DeviceDetachFailed as err: ++ with excutils.save_and_reraise_exception(): ++ LOG.warning('Guest refused to detach volume %(vol)s', ++ {'vol': volume_id}, instance=instance) + except Exception: + with excutils.save_and_reraise_exception(): + LOG.exception('Failed to detach volume ' |
