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. -- Greetings Anu Bhaskar ---- On Thu, 01 Oct 2015 13:07:15 +0530 Markos Gogoulos <mgogou...@mist.io> wrote ---- 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').
