ONTAP 9
卷移动

问题描述

一段时间后，数据更改率较高的大型卷的卷移动会使吞吐量下降到小于2 MB (如volume move show 中所示)
Move State 为"healthy "
Bytes Sent 值会继续增加
如果在源中更改或写入了其他数据、则Percentage Completed 可能会发生倒退
没有Cutovers Attempted 或Times Cutover Hard/Soft Deferred
示例： volume move show 命令输出显示KB/s吞吐量和较高的估计完成时间(为简洁起见、删除了某些行)。

Cluster::> volume move show -volume vol1 -vserver svm1 Vserver Name: svm1 Volume Name: vol1 Actual Completion Time: - Bytes Remaining: 4.50TB Bytes Sent: 29.19TB Cutovers Attempted: 0 Times Cutover Hard Deferred: 0 Times Cutover Soft Deferred: 0 Destination Aggregate: node1-aggr1 Detailed Status: Transferring data: 29.19TB sent. Estimated Time of Completion: Fri Apr 04 12:38:31 2025 Job ID: 4583 Managing Node: node1 Percentage Complete: 85% Move Phase: replicating Estimated Remaining Duration: 33 days 22:56 Replication Throughput: 404.4KB/s Duration of Move: 18:54:17 Source Aggregate: node2-aggr1 Start Time of Move: Fri Feb 28 17:47:55 2025 Move State: healthy
