openstack计算节点的zone划分

swsrl

　　初步了解了一些openstack zone的使用方法，觉得比较实用，在此分享给大家：

　　# nova aggregate-list  
　　Print a list of all aggregates.
　　# nova aggregate-create   
　　Create a new aggregate named  in availability zone . Returns the ID of the newly created aggregate.  
　　# nova aggregate-delete   
　　Delete an aggregate with id .  
　　# nova aggregate-details   
　　Show details of the aggregate with id .  
　　# nova aggregate-add-host   
　　Add host with name  to aggregate with id .
　　# nova aggregate-remove-host   
　　Remove the host with name  from the aggregate with id .  
　　# nova aggregate-set-metadata   [ ...]  
　　Add or update metadata (key-value pairs) associated with the aggregate with id .  
　　# nova aggregate-update   []  

　　Update the aggregate's name and optionally availability zone.    
　　# nova host-list  
　　List all hosts by service.  
　　# nova host-update --maintenance [enable | disable]  

　　Put/resume host into/from maintenance.

　　举例：
　　[iyunv@openstack ~]# nova aggregate-list
　　+----+------+-------------------+
　　| Id | Name | Availability Zone |
　　+----+------+-------------------+
　　+----+------+-------------------+
　　[iyunv@openstack03 ~]# nova aggregate-create clusterA cluster-12C-128G
　　+----+----------+-------------------+-------+--------------------------------------+
　　| Id | Name     | Availability Zone | Hosts | Metadata                             |
　　+----+----------+-------------------+-------+--------------------------------------+
　　| 1  | clusterA | cluster-12C-128G  |       | 'availability_zone=cluster-12C-128G' |
　　+----+----------+-------------------+-------+--------------------------------------+
　　[iyunv@openstack03 ~]# nova aggregate-create clusterB cluster-12C-48G
　　+----+----------+-------------------+-------+-------------------------------------+
　　| Id | Name     | Availability Zone | Hosts | Metadata                            |
　　+----+----------+-------------------+-------+-------------------------------------+
　　| 2  | clusterB | cluster-12C-48G   |       | 'availability_zone=cluster-8C-48G' |
　　+----+----------+-------------------+-------+-------------------------------------+
　　[iyunv@openstack03 ~]# nova aggregate-list
　　+----+----------+-------------------+
　　| Id | Name     | Availability Zone |
　　+----+----------+-------------------+
　　| 1  | clusterA | cluster-12C-128G  |
　　| 2  | clusterB | cluster-8C-48G   |
　　+----+----------+-------------------+
　　[iyunv@openstack03 ~]# nova aggregate-list
　　+----+----------+-------------------+
　　| Id | Name     | Availability Zone |
　　+----+----------+-------------------+
　　| 1  | clusterA | cluster-12C-128G  |
　　| 3  | clusterB | cluster-8C-48G    |
　　+----+----------+-------------------+
　　[iyunv@openstack03 ~]# nova aggregate-add-host 1 node01
　　Host node01 has been successfully added for aggregate 1
　　+----+----------+-------------------+----------+--------------------------------------+
　　| Id | Name     | Availability Zone | Hosts    | Metadata                             |
　　+----+----------+-------------------+----------+--------------------------------------+
　　| 1  | clusterA | cluster-12C-128G  | 'node01' | 'availability_zone=cluster-12C-128G' |
　　+----+----------+-------------------+----------+--------------------------------------+
　　[iyunv@openstack03 ~]# nova aggregate-add-host 2 node02
　　Host node02 has been successfully added for aggregate 2
　　+----+----------+-------------------+--------------------+--------------------------------------+
　　| Id | Name     | Availability Zone | Hosts              | Metadata                             |
　　+----+----------+-------------------+--------------------+--------------------------------------+
　　| 1  | clusterA | cluster-8C-48G  | 'node02' | 'availability_zone=cluster-8C-48G' |
