XtremIO:無法檢視原生複寫快照集
Summary: 嘗試透過 CLI 和 UI 檢視原生複製建立的快照集時,會顯示找不到相符訊息。
Symptoms
嘗試檢視原生複寫建立的快照集會導致 CLI 和 UI 中出現找不到相符訊息:xmcli (tech)> show-remote-protection-snapshot-sets protection-session-id=1No matches foundxmcli (tech)> show-remote-protection-snapshot-sets protection-session-id=2No matches found
但是,透過檢查保護工作階段,系統會建立快照集:xmcli (tech)> show-remote-protection-session protection-session-id=1 Name: <Remote protection session name> Index: 1 Replication-State: active Replication-State-Details: Replication-Direction: source_to_target Block-Access-Type: read_only Source-XMS-Id: Name: <XMS name> Index: 0 Source-Cluster-ID: Name: <Cluster name> Index: 1 Source-CG-Id: Name: <CG name> Index: 2 Target-XMS-Id: Name: <XMS name> Index: 0 Target-Cluster-ID: Name: <Cluster name> Index: 1 Target-CG-Id: Name: <CG name> Index: 1 Num-Of-Vols: 3 RPO: 60 Max-BW(MB/s): 0.000 Protection-Window-Num-Copies: 27 Protection-Window-Duration-in-Days: 4.000 Current-Protection-Window-Copies: 10 Source-Retention-Policy-ID: Name: <Retention policy name> Index: 1 Target-Retention-Policy-ID: Name: <Retention policy name> Index: 1 Number-Of-Target-PITs: 10 Target-Pit-Num-Copies-Status: ok Target-Pit-Window-Size-Status: protection_window_not_full Number-Of-Source-PITs: 2 Next-Scheduled-Cycle: xxxxxxxx Replication-Mode: async Lag: 30 BW(KB/s): 0 Max-BW(MB/s): 0.000 Transfer-Efficiency-Ratio(Ratio): 1 Cycle-Start-Time(Timestamp): Tue Sep 17 15:37:43 2019 Last-Cycle-Start-Time(Timestamp): Tue Sep 17 15:37:43 2019 Last-Cycle-Completed-Snapshot-Set: xxxxxxxxx Last-Cycle-Duration: 1 Last-Cycle-Link-BW(KB/s): 70086 Last-Cycle-Effective-Bandwidth(KB/s): 13981303 Last-Cycle-Transfer-Efficiency-Ratio: 199.48671427 Cycle-Number(Count): 910 Num-Missing-Short-Period-Snapshot-Sets: 14 Num-Missing-Middle-Period-Snapshot-Sets: 3 Num-Missing-Long-Period-Snapshot-Sets: 0 Target-Missing-Pits-Alert: enabled Test-Copy-Mode: False Snapset-Backup-Snapset-Index: [] Current-Command-Name: Current-Command-Status: none Replication-Session-Consistency-State: consistent Obj-Severity: information
Cause
導致 XtremIO 管理伺服器 (XMS) 上的任務程式程式停止運作的程式碼錯誤。這會影響 XMS 執行的 auto_sync 工作,並最終影響其從陣列收集原生複寫快照資訊的方式。
Resolution
發現這是陣列上目前軟體的程式碼錯誤,因應措施是可透過 CLI 執行重新整理。
Additional Information
如果重新開機 XMS 無法運作,請執行下列 POA:
確保客戶知道執行 XMS 復原會導致效能資料及其標籤遺失。客戶核准 XMS 復原後,請執行下列步驟:
在兩個 XtremIO 管理伺服器上執行 xms-recovery:
- 在源 XMS 上試運行 XMS-恢復;如果試執行成功,則在來源 XMS 上進行 XMS 復原。
- 在目標 XMS 上試運行 XMS-恢復;如果試執行成功,則目標 XMS 上的 XMS-Recovery。
