is there a trace for the failure in the log? if so, can you paste it? GlusterFS doesn't do zeroing. The I/O done depends on which snapshot is being deleted, but in some cases (deleting the active snapshot) where the base volume image must be copied into the snapshot qcow2 file, so the time it takes is dependent on the size of the volume. Can you attach a Nova compute log from when this occurred? It is likely that we need Nova to send updates to Cinder while a long operation is occurring so it knows not to time out the operation.

compute.log
Actually, after reviewing the compute log, this looks like an instance of bug 1040711.

Created attachment 849959 [details] volume.log Description of problem: Cinder failed to delete a snapshot create with instance snapshot. Cinder is using GlusterFS as its backend. 1. Cinder is able to delete volumes. 2. Cinder is able to delete snapshots which haven't been created by instance snapshot. Version-Release number of selected component (if applicable): python-cinderclient-1.0.7-2.el6ost.noarch python-cinder-2013.2.1-4.el6ost.noarch openstack-cinder-2013.2.1-4.el6ost.noarch How reproducible: 100% Steps to Reproduce: 1. Create an volume from an image. 2. Launch an instance with this volume 3. Take a snapshot of the instance. 4. Delete the volume snapshot. Actual results: The snapshot is in the status of 'deleting', until trying to delete it again and then it is in the status of 'error_deleting'. Expected results: The snapshot should be deleted. Additional info: The logs are attached.
