Comment 2 Stephen Gordon 2013-11-13 13:24:47 UTC

I am guessing that the disk_bus of the volume is set to IDE, which means that just like an IDE disk in a physical server the volume can not be hot plugged.

You must either:

    * Create or update the volume so that the disk_bus value is set to a bus that does support hotplugging (such as virtio) if your Hypervisor and guests support it.

    * Shutdown the instance to attach the volume.

For example you would create a 1G volume that uses the virtio bus using this command:

# cinder create --metadata disk_bus=virtio 1

Comment 3 Fedora Admin XMLRPC Client 2013-12-16 16:18:00 UTC

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

Comment 4 Xavier Queralt 2014-03-10 13:21:48 UTC

As Stephen pointed out, a disk cannot be hot plugged when using the IDE bus. If the process in comment 2 doesn't work as expected, please reopen the bug.
