Title:
Nova volume-update leaves volumes stuck in attaching/detaching
Status in Cinder:
Incomplete
Status in OpenStack Compute (nova):
Expired
Bug description:
There is a problem with the nova command 'volume-update' that leaves
cinder volumes in the states 'attaching' and 'deleting'.
If the nova command 'volume-update' is used by a non admin user the
command fails and the volumes referenced in the command are left in
the states 'attaching' and 'deleting'.
For example, if a non admin user runs the command
$ nova volume-update d39dc7f2-929d-49bb-b22f-56adb3f378c7
f0c3ea8f-c00f-4db8-aa20-e2dc6a1ddc9b 59b0cf66-67c8-4041-a505-78000b9c71f6
Will result in the two volumes stuck like this:
$ cinder list
+--------------------------------------+-----------+--------------+------+-------------+----------+--------------------------------------+
| ID | Status | Display Name | Size |
Volume Type | Bootable | Attached to |
+--------------------------------------+-----------+--------------+------+-------------+----------+--------------------------------------+
| 59b0cf66-67c8-4041-a505-78000b9c71f6 | attaching | vol2 | 1 |
None | false | |
| f0c3ea8f-c00f-4db8-aa20-e2dc6a1ddc9b | detaching | vol1 | 1 |
None | false | d39dc7f2-929d-49bb-b22f-56adb3f378c7 |
+--------------------------------------+-----------+--------------+------+-------------+----------+--------------------------------------+

The problem is that the nova policy.json file allows a non admin user to run
the command 'volume-update', but the cinder policy.json file requires the admin
role to run the action os-migrate_volume_completion, which is called by nova as
part of the 'update-volume' process.
The operation will complete successfully if it is performed by an
admin user, or if it is run by a non admin user after the cinder
policy.json file is updated.
The simplest fix would be to remove the "rule:admin_api" requirement from the
"os-migrate_volume_completion" action in cinder policy.json
