建立硬碟區鏡像

CubeCOS 磁碟區鏡像功能的先決條件​

  • 請確保兩個叢集具有相同的 使用者名稱。
  • 請確保兩個叢集具有相同的 專案名稱。
  • 請確認兩個叢集的所有服務狀態皆為 正常。
  • 取得叢集1的VIP：例如 10.32.31.10
  • 取得叢集2的 VIP：例如 10.32.10.140

設定 CubeCOS 叢集間的磁碟鏡像​

  1. 在叢集1的專案管理員上啟動虛擬機器，本例中使用test。

設定遠端抄寫目標​

cluster1(primary)​

  1. 設定遠端對等端點 CLI > 儲存 > 鏡像 > 站點 > 對等端點
   cluster1> storage mirror
   cluster1:mirror> site
   cluster1:site> pair
   Enter IP address (required): 10.32.10.140
   Enter remote secret (required): bigstack
   Warning: Permanently added '10.32.10.140' (ED25519) to the list of known hosts.
  1. 檢查連結狀態 CLI > 儲存 > 鏡像 > 狀態
   cluster1:mirror> status
   Local time: 2025-05-14 13:39:10
   +----------------------------------------------+----------------------------------------------+
   |         (local) control-10.32.31.10-site OK |         (remote) control-10.32.10.140-site OK |
   +----------------------------------------------+----------------------------------------------+

cluster2(secondary)​

  1. 檢查連結狀態 CLI > 儲存 > 鏡像 > 狀態
   cluster2:mirror> status
   Local time: 2025-05-14 14:07:25
   +----------------------------------------------+----------------------------------------------+
   |         (local) control-10.32.10.140-site OK |         (remote) control-10.32.31.10-site OK |
   +----------------------------------------------+----------------------------------------------+

在 cluster1 上選取虛擬機儲存，用於同步至所有遠端抄寫目標​

   cluster1:mirror> rule
   cluster1:rule> enable
   cluster1:enable> journal
   Select volume:
   1: volume: 71922a77-03af-4563-936e-cb66f747d066, status: in-use, size: 40GB, attach: /dev/sda on test
   Enter index: 1
   cinder-volumes/volume-71922a77-03af-4563-936e-cb66f747d066 enabled in journal mode

  1. 在叢集1（主節點）上持續監控同步狀態直至完成

    命令列介面 > 儲存 > 鏡像 > 狀態

   cluster1:mirror> status
   Local time: 2025-05-14 14:29:07
   +----------------------------------------------+----------------------------------------------+
   |         (local) control-10.32.31.10-site OK  |        (remote) control-10.32.10.140-site OK |

   | 71922a77-03af-4563-936e-cb66f747d066 (journal)                       (40G) /dev/sda on test |
   |        local image is primary     up+stopped |                        synced   up+replaying |
   +----------------------------------------------+----------------------------------------------+

  1. 在叢集2（次要節點）上持續監控同步狀態直至完成

    命令列介面 > 儲存 > 鏡像 > 狀態

   cluster2:mirror> status
   Local time: 2025-05-14 14:29:19
   +----------------------------------------------+----------------------------------------------+
   |         (local) control-10.32.10.140-site OK |         (remote) control-10.32.31.10-site OK |
   +----------------------------------------------+----------------------------------------------+
   | 71922a77-03af-4563-936e-cb66f747d066 (journal)                                       (40G)  |
   |                        synced   up+replaying |       remote image is primary     up+stopped |
   +----------------------------------------------+----------------------------------------------+

驗證在 cluster2 上是否會自動建立新的儲存 volume​

/assets/volumes/skyline-vm-2.png

對 cluster1 中被鏡像到虛擬機 test 的磁碟進行變更​

/assets/volumes/skyline-vm-3.png

在 cluster2(secondary) 上檢查資料抄寫狀態確認備份資料有成功抄寫​

cluster2:mirror> status
Local time: 2025-05-14 14:32:25
+----------------------------------------------+----------------------------------------------+
|         (local) control-10.32.10.140-site OK |         (remote) control-10.32.31.10-site OK |
+----------------------------------------------+----------------------------------------------+

|                        synced   up+replaying |       remote image is primary     up+stopped |
+----------------------------------------------+----------------------------------------------+

在 cluster2(secondary) 上進行映像檔 Promote​

若主叢集發生災難，您需要提升備援叢集。

命令列介面 > 儲存 > 鏡像 > 提升

cluster2:mirror> promote
1: normal
2: force
Enter index: 1
1: site
2: volume
Enter index: 2
Select volume:
1: volume-71922a77-03af-4563-936e-cb66f747d066
Enter index: 1
normal promote cinder-volumes/volume-71922a77-03af-4563-936e-cb66f747d066 on local site

檢查 cluster1（primary）的抄寫狀態​

檢查鏡像狀態是否已變更。

叢集1成為次要叢集，叢集2成為主要叢集。

命令列介面 > 儲存 > 鏡像 > 狀態

cluster1:mirror> status

Verify the VM test is shut off on cluster1(switch to secondary)​

/assets/volumes/skyline-vm-4.png

Call up a VM attached to the mirrored image on cluster2(switch to primary)​

  1. 將游標懸停於「更多」選項上，接著點選「虛擬機相關」，最後點擊「建立虛擬機」。
