to 'administrator'.

Failed to attach a volume after detaching the same volume.

Solution

|
|
|

You must change the device name on the :command:`nova-attach` command. The VM
|
|
might not clean up after a :command:`nova-detach` command runs. This example
|
|
shows how the :command:`nova-attach` command fails when you use the ``vdb``,
|
|
``vdc``, or ``vdd`` device names:
|
|
|
|
.. code-block:: console
|
|
|
|
# ls -al /dev/disk/by-path/
|
|

You might also have this problem after attaching and detaching the same
|
|
volume from the same VM with the same mount point multiple times. In
|
|
this case, restart the KVM host.
