Resize

1. 列印目前 server DYW_Master 使用的 flavor 為 fv_DYW。

   [root@ip110 ~]<demo># openstack server list
   +--------------------------------------+------------+---------+-----------+--------+--------+
   | ID                                   | Name       | Status  | Networks  | Image  | Flavor |
   +--------------------------------------+------------+---------+-----------+--------+--------+
   | a5f03d78-4436-4c0e-ad24-4dc0a6553700 | DYW_Master | SHUTOFF | provider= | dyw2   | fv_DYW |
   +--------------------------------------+------------+---------+-----------+--------+--------+
   

2. 查詢 flavor，fv_DYW disk 16G, RAM 2G。

   [root@ip110 ~]<demo># openstack flavor list
   +----+-----------+------+------+-----------+-------+-----------+
   | ID | Name      |  RAM | Disk | Ephemeral | VCPUs | Is Public |
   +----+-----------+------+------+-----------+-------+-----------+
   | 0  | fv_cirros |   64 |    1 |         0 |     1 | True      |
   | 1  | dyw.ce8   | 4096 |   30 |         0 |     2 | True      |
   | 2  | fv_Win10  | 8192 |   30 |         0 |     4 | True      |
   | 3  | fv_DYW    | 2048 |   16 |         0 |     2 | True      |
   +----+-----------+------+------+-----------+-------+-----------+
   

3. Server DYW_Master resize 成 flavor dyw.ce8，也就是 Disk 30G, RAM 4G。

   [root@ip110 ~]<demo># openstack server resize --flavor dyw.ce8 DYW_Master
   

4. 執行 resize 後，server DYW_Master 狀態進入 VERIFY_RESIZE，使用的 falvor 已改成 dyw.ce8。

5. 因為已設定 resize_confirm_window=5：自動確認時間間隔為 5 秒，可不用執行 confirm 進行確認。

   [root@ip110 ~]<demo># openstack server resize --confirm DYW_Master
   

6. Confirm 確認後，server DYW_Master 狀態進入 ACTIVE。

   [root@ip110 ~]<demo># openstack server show DYW_Master
