Fixed In Version: openstack-cinder-2013.2-4.el6ost
Doc Type: Bug Fix
Doc Text:
When cloning volumes, the GlusterFS volume driver used by the Block Storage service did not set the correct permissions for volume files. This caused subsequent operations on these cloned volumes to fail. With this fix, the GlusterFS volume driver now sets the correct permissions when cloning a volume.

Description of problem:

working with glusterfs (so might be related to gluster)

Version-Release number of selected component (if applicable):

openstack-cinder-2013.2-2.el6ost.noarch

How reproducible:

100%

Steps to Reproduce:
1. create a volume and clone a volume from it: 
cinder create <size> --display-name <name> 
cinder create <size> --source-volid <volume> --display-name <name>
2. extend the volume: 
cinder extend <volume> <size> 
3.

Actual results:

Expected results:

we should be able to extend the volume
