device parameter errors out while attaching a volume in openstack
Hi,
While attaching a volume to an instance in Openstack, if I omit the device name or if I specify the device name as auto, attach_volume call errors out.
Traceback (most recent call last):
File "attach_volume_v1.py", line 44, in <module>
success = driver.attach_volume(instances[0], volumes[0], device = 'auto')
File "/usr/lib/python2.7/site-packages/libcloud/compute/drivers/openstack.py", line 226, in attach_volume
'device': device,
File "/usr/lib/python2.7/site-packages/libcloud/common/openstack.py", line 202, in request

response = responseCls(**kwargs)

Hi Markos,
Setting device parameter to None resolved the error. Openstack is now automatically assigning a device.
driver.attach_volume(instances[0], volumes[0], device = None)
However omitting device parameter resulted in same error.

Hi,
I haven't used these functions, but I see on
http://developer.openstack.org/api-ref-compute-v2-ext.html the device
parameter should be provided as
"Name of the device such as, /dev/vdb. Omit or set this parameter to null
for auto-assignment, if supported. If you specify this parameter, the
device must not exist in the guest operating system."
Seems that the 'auto' is reserved by the system, so attach_volume function
of compute.drivers.openstack.py should omit this parameter if it is not
specified (or if it is specified as 'auto').

Markos
