卷效率开始失败、并显示错误"未启用数据压缩"。使用选项-a和-b无效

适用场景

• ONTAP 9.8 及更高版本
• 存储效率 
• 温度敏感型存储效率（ TSSE ）

问题描述

尝试重新扫描卷以节省效率时、包括快照和/或共享块、此时会报告以下错误：

cluster01::> set -privilege advanced
cluster01::*> vol efficiency start -volume vol1 -scan-old-data true -snapshot-blocks true
 
Warning: This operation scans all of the data in volume "vol1" of Vserver "svm1". It might take a significant time, and degrade performance during that time.
     Use of "-snapshot-blocks|-b" option can increase space usage as data which is part of Snapshot will be compressed.
Do you want to continue? {y|n}: y
 
Error: command failed: Failed to start efficiency on volume "vol1" of Vserver "svm1": Compression is not enabled. Use of options -a and -b is not valid.
