Dmitry Tantsur be221ecb0f Correct examples in "Manage Compute services" documentation 
* "compute service set" command requires a host, not a zone
* the --disable-reason flag's argument has to be quoted

Manage Compute services

You can enable and disable Compute services. The following examples disable and enable the nova-compute service.

  1. List the Compute services:

    $ openstack compute service list
+----+--------------+------------+----------+---------+-------+--------------+
| ID | Binary       | Host       | Zone     | Status  | State | Updated At   |
+----+--------------+------------+----------+---------+-------+--------------+
|  4 | nova-        | controller | internal | enabled | up    | 2016-12-20T0 |
|    | consoleauth  |            |          |         |       | 0:44:48.0000 |
|    |              |            |          |         |       | 00           |
|  5 | nova-        | controller | internal | enabled | up    | 2016-12-20T0 |
|    | scheduler    |            |          |         |       | 0:44:48.0000 |
|    |              |            |          |         |       | 00           |
|  6 | nova-        | controller | internal | enabled | up    | 2016-12-20T0 |
|    | conductor    |            |          |         |       | 0:44:54.0000 |
|    |              |            |          |         |       | 00           |
|  9 | nova-compute | compute    | nova     | enabled | up    | 2016-10-21T0 |
|    |              |            |          |         |       | 2:35:03.0000 |
|    |              |            |          |         |       | 00           |
+----+--------------+------------+----------+---------+-------+--------------+

  2. Disable a nova service:

    $ openstack compute service set --disable --disable-reason "trial log" compute nova-compute
+----------+--------------+----------+-------------------+
| Host     | Binary       | Status   | Disabled Reason   |
+----------+--------------+----------+-------------------+
| compute  | nova-compute | disabled | trial log         |
+----------+--------------+----------+-------------------+

  3. Check the service list:

    $ openstack compute service list
+----+--------------+------------+----------+---------+-------+--------------+
| ID | Binary       | Host       | Zone     | Status  | State | Updated At   |
+----+--------------+------------+----------+---------+-------+--------------+
|  4 | nova-        | controller | internal | enabled | up    | 2016-12-20T0 |
|    | consoleauth  |            |          |         |       | 0:44:48.0000 |
|    |              |            |          |         |       | 00           |
|  5 | nova-        | controller | internal | enabled | up    | 2016-12-20T0 |
|    | scheduler    |            |          |         |       | 0:44:48.0000 |
|    |              |            |          |         |       | 00           |
|  6 | nova-        | controller | internal | enabled | up    | 2016-12-20T0 |
|    | conductor    |            |          |         |       | 0:44:54.0000 |
|    |              |            |          |         |       | 00           |
|  9 | nova-compute | compute    | nova     | disabled| up    | 2016-10-21T0 |
|    |              |            |          |         |       | 2:35:03.0000 |
|    |              |            |          |         |       | 00           |
+----+--------------+------------+----------+---------+-------+--------------+

  4. Enable the service:

    $ openstack compute service set --enable compute nova-compute
+----------+--------------+---------+
| Host     | Binary       | Status  |
+----------+--------------+---------+
| compute  | nova-compute | enabled |
+----------+--------------+---------+
