哪些条件可以触发卷的自动缩减？
This article may include metadata, visibility, validation state, and related support guidance.
适用场景
- ONTAP 9
- volume autosize
问题解答
- 必须满足以下三个条件：
-autosize-mode参数设置为grow_shrink。- 现有卷大小大于中设置的值
-min-autosize。 - 现有卷的利用率低于中设置的值
-autosize-shrink-threshold-percent。

- 此外、 [1] ONTAP 9.14.1或更高版本中的重新平衡FlexGroup卷也可能会在FlexGroup的成分卷(成分卷、CV)之间触发大小调整
