问题解答

问题1.  使用选项wait 进行转换、按如下所示实施卷移动操作、完成到  cutover_hard_deferred 阶段、 源卷上的新数据是否会继续复制到目标
 
示例:
::*> volume move modify -vserver cluster4_svm1 -volume testmove -cutover-action wait
 
::*> volume move show
Vserver  Volume   State   Move Phase Percent-Complete Time-To-Complete
--------- ---------- -------- ---------- ---------------- ----------------
cluster4_svm1
testmove  alert  cutover_hard_deferred
98%
 
回答1.  是的,数据正在持续传输,可 通过命令'vol move show -ins' 观察到这一点:
 
示例:
ontap913::> vol move show -ins

              Vserver Name: test1
               Volume Name: voltest2
         Actual Completion Time: -
             Bytes Remaining: 136.0KB
          Destination Aggregate: aggr2_node1
            Detailed Status: Cutover Deferred, Waiting for user intervention (2.52MB Sent)::Volume move job preparing transfer.
      Estimated Time of Completion: -
              Managing Node: ontap913-01
           Percentage Complete: 94%
               Move Phase: cutover_hard_deferred
      Estimated Remaining Duration: -
         Replication Throughput: 196KB/s
            Duration of Move: 00:20:43
            Source Aggregate: aggr1_node1
           Start Time of Move: Fri Nov 01 13:19:17 2024
               Move State: alert
       Is Source Volume Encrypted: false
   Encryption Key ID of Source Volume:
     Is Destination Volume Encrypted: false
Encryption Key ID of Destination Volume:

ontap913::> vol move show -ins

              Vserver Name: test1
               Volume Name: voltest2
         Actual Completion Time: -
             Bytes Remaining: 124.0KB
          Destination Aggregate: aggr2_node1
            Detailed Status: Cutover Deferred, Waiting for user intervention (2.71MB Sent)::Volume move job preparing transfer.
      Estimated Time of Completion: -
              Managing Node: ontap913-01
           Percentage Complete: 94%
               Move Phase: cutover_hard_deferred
      Estimated Remaining Duration: -
         Replication Throughput: 188KB/s
            Duration of Move: 00:21:40
            Source Aggregate: aggr1_node1
           Start Time of Move: Fri Nov 01 13:19:17 2024
               Move State: alert
       Is Source Volume Encrypted: false
   Encryption Key ID of Source Volume:
     Is Destination Volume Encrypted: false

 

 
 
问题2:由于上述状态、将触发转换、但未按以下方式完成消息、然后暂停卷移动、 源卷上的新数据是否会继续复制到目标卷?
 
示例:
::*> vol move trigger-cutover -vserver cluster4_svm1 -volume testmove -force true
 
Detailed Status: Waiting to Cutover. (Preparing source volume for cutover: Deduplication is not ready for volmove cutover Sent)::Reason: xx.xxTB Volume move job monitoring transfer of data.
 
::*> vol move pause -vserver cluster4_svm1  -volume testmove 
 
答2.否、新数据将暂停传输到目标卷。
 
 
第3季度。复制吞吐量约为5 MB/秒是否正常?
 
回答3.复制吞吐量取决于系统情况、例如工作负载、 同时执行了多少卷移动、客户端IO、效率等。有关详细信息、请参见文档:  Is Storage Performance Impered your volume mover or cutover?
 
 
问题4:如何将上述卷移动恢复为转换等待 状态。
 
4.由于tigger-cutover 已 通过-force true 选项实施、然后 它在此状态下暂停、  因此可通过'vol move show -ins' 命令检查以下内容、使 其无法将卷移动恢复到转换状态、因此 转换将强制执行。
 
Specified Action For Cutover: force
 
如果需要使用转换来等待此卷移动、请恢复并立即中止此操作、并计划一次新的卷移动、因为已清除现有移动。
 
示例:
::*> vol move resume -vserver cluster4_svm1  -volume testmove 
::*> vol move abort -vserver cluster4_svm1  -volume testmove
