Host aggregates
现在我们需要使用 host aggregates 逻辑分离这两个 hypervisors，为了实现这个，我们创建了两个 aggregates：
代码语言：javascript复制$ nova aggregate-create ceph-compute-storage1
---- ----------------------- ------------------- ------- ----------
| Id | Name | Availability Zone | Hosts | Metadata |
---- ----------------------- ------------------- ------- ----------
| 1 | ceph-compute-storage1 | - | | |
---- ----------------------- ------------------- ------- ----------
$ nova aggregate-create ceph-compute-storage2
---- ----------------------- ------------------- ------- ----------
| Id | Name | Availability Zone | Hosts | Metadata |
---- ----------------------- ------------------- ------- ----------
| 2 | ceph-compute-storage2 | - | | |
---- ----------------------- ------------------- ------- ---------- 现在添加 hypervisor 到他们各自的 aggregates：
代码语言：javascript复制$ nova aggregate-add-host ceph-compute-storage1 compute-ceph1
Host compute-ceph1 has been successfully added for aggregate 1
---- ----------------------- ------------------- ----------------- ----------
| Id | Name | Availability Zone | Hosts | Metadata |
---- ----------------------- ------------------- ----------------- ----------
| 1 | ceph-compute-storage1 | - | 'compute-ceph1' | |
---- ----------------------- ------------------- ----------------- ----------
$ nova aggregate-add-host ceph-compute-storage2 compute-ceph2
Host compute-ceph2 has been successfully added for aggregate 2
---- ----------------------- ------------------- ----------------- ----------
| Id | Name | Availability Zone | Hosts | Metadata |
---- ----------------------- ------------------- ----------------- ----------
| 2 | ceph-compute-storage2 | - | 'compute-ceph2' | |
---- ----------------------- ------------------- ----------------- ---------- 最后设置一个特定的元数据，稍后会被 Nova flavor 记录：
代码语言：javascript复制$ nova aggregate-set-metadata 1 cephcomputestorage1=true
Metadata has been successfully updated for aggregate 1.
---- ----------------------- ------------------- ----------------- ----------------------------
| Id | Name | Availability Zone | Hosts | Metadata |
---- ----------------------- ------------------- ----------------- ----------------------------
| 1 | ceph-compute-storage1 | - | 'compute-ceph1' | 'cephcomputestorage1=true' |
---- ----------------------- ------------------- ----------------- ----------------------------
$ nova aggregate-set-metadata 2 cephcomputestorage2=true
Metadata has been successfully updated for aggregate 2.
---- ----------------------- ------------------- ----------------- ----------------------------
| Id | Name | Availability Zone | Hosts | Metadata |
---- ----------------------- ------------------- ----------------- ----------------------------
| 2 | ceph-compute-storage2 | - | 'compute-ceph2' | 'cephcomputestorage2=true' |
---- ----------------------- ------------------- ----------------- ----------------------------
