Hi I'm creating a storage volume in a storage pool (directory type). I'd like to create a volume that creates a file in a sub directory under the directory that the pool points to but am not able to work out how, maybe it is not possible? My pool was created using following xml... <pool type='dir'> <name>nova-local-pool</name> <target> <path>/home/pcarlton/openstack/stuff/instances</path> <permissions> <mode>0755</mode> <owner>1000</owner> <group>130</group> </permissions> </target> </pool> The volume was created using this xml... stgvol_xml = """ <volume> <name>4291f96a-759a-4b8a-bfe2-7a8ccb118b75-disk</name> <allocation>0</allocation> <capacity unit="G">1</capacity> <target> <format type='qcow2'/> <permissions> <owner>1000</owner> <group>130</group> <mode>0644</mode> <label>image_overlay</label> </permissions> </target> <backingStore> <path>/home/pcarlton/openstack/stuff/nova/instances/_base/07f224f72581f8e029e08ff96827d581b2321a7b</path> <format type='raw'/> <permissions> <owner>1000</owner> <group>130</group> <mode>0644</mode> <label>image_base</label> </permissions> </backingStore> </volume>""" All works ok but I'd like the create the 'disk' file in /home/pcarlton/openstack/stuff/nova/instances/4291f96a-759a-4b8a-bfe2-7a8ccb118b75 Thanks -- Paul Carlton Software Engineer Cloud Services Hewlett Packard Enterprise BUK03:T242 Longdown Avenue Stoke Gifford Bristol BS34 8QZ Mobile: +44 (0)7768 994283 Office: +44 (0)117 316 2189 Email: mailto:paul.carlton2@hpe.com irc: paul-carlton2 Hewlett-Packard Enterprise Limited registered Office: Cain Road, Bracknell, Berks RG12 1HN Registered No: 690597 England.
