Description Giulio Fidente 2014-01-07 13:56:53 UTC 
Created attachment 846681 [details]
cinder_emc_volume_from_image_trace.txt

Description of problem:
When Cinder is configured to use the EMC driver(*), creation of volumes from images fails. Attached to the bug is the trace appearing in volume.log

* cinder.volume.drivers.emc.emc_smis_iscsi.EMCSMISISCSIDriver


Version-Release number of selected component (if applicable):
openstack-cinder-2014.1-0.2.b1.el6.noarch


Steps to Reproduce:
1. configure Cinder with the EMC driver
2. try to create a volume using the "--image-id" option
Comment 1 Giulio Fidente 2014-01-07 15:42:27 UTC 
I attempted to troubleshoot this and "fixed" the initial issue by installing the iscsi-initiator-utils package.

Yet, the operation is still failing with a wierd error from the CMI (SMI-S):

  2014-01-07 16:21:59.463 1213 TRACE cinder.openstack.common.rpc.amqp   File "/usr/lib/python2.6/site-packages/cinder/volume/drivers/emc/emc_smis_common.py", line 1380, in find_device_number

  2014-01-07 16:21:59.463 1213 TRACE cinder.openstack.common.rpc.amqp CIMError: (1, u'A general error occurred that is not covered by a more specific error code. (com.emc.cmp.osls.se.osl.Maskin

must be fully synchronized before performing this operation.)')

While at first look that looks like an issue with the EMC CIM software itself, the software is instead working fine when Cinder attempts to create a new empty volume.

Upstream bug has been marked invalid, and Giulio reported upstream that he was no longer experiencing this problem.
