设置缓存策略时、无法在ONTAP 中设置QoS策略组

适用场景

• ONTAP 9.9.1

问题描述

如果在SVM上启用了缓存策略、则无法将QoS策略设置为卷

cluster1::> vserver show -vserver svm1 -fields caching-policy,qos-policy-group
vserver qos-policy-group caching-policy
------- ---------------- --------------
svm1   -         auto

cluster1::> volume modify -vserver svm1 -volume vol1 -qos-policy-group performance-fixed

Error: command failed: Volume "vol1" cannot be in a QoS policy group because its parent Vserver "svm1" already has a policy group.  Either modify Vserver "svm1" to set its QoS policy group to "none" or do not assign a policy group to
    Volume "vol1". Use the "qos workload show" command to view all QoS workloads.
