The problem here is that when using LIO, the iscsi_targets table does not get an entry until an attach is attempted (which is when the LIO target is created for that volume). The delete path expects there to always be a target id in that table tied to that volume, but that is not guaranteed to the be the case. LioAdm's remove_export tries to handle this via "except exception.NotFound:" but that is referencing cinder.brick.exception.NotFound rather than cinder.exception.NotFound so the error is not skipped. |
Created attachment 882276 [details] cinder volume log Description of problem: on lvm with rhel7 I fail to delete a volume with ISCSITargetNotFoundForVolume Version-Release number of selected component (if applicable): [root@orange-vdsf ~(keystone_admin)]# rpm -qa |grep cinder python-cinderclient-1.0.7-2.el7.noarch openstack-cinder-2014.1-0.6.b3.el7.noarch python-cinder-2014.1-0.6.b3.el7.noarch How reproducible: 100% Steps to Reproduce: 1. install AIO with lvm backend for cinder 2. create a volume (cinder create 1) 3. delete the volume (cinder delete <volume>) Actual results: we fail to delete the volume with raise exception.ISCSITargetNotFoundForVolume Expected results: we should be able to delete the volume Additional info: full log attached 2014-04-03 16:32:20.140 2616 DEBUG
