Supported and unsupported features for FlexCache volumes

You must be aware of the features that are supported by FlexCache volumes and their origin volumes.

Feature	Supported at the origin volume?	Supported at the FlexCache volume?
Antivirus	Yes Supported starting with ONTAP 9.7	Not applicable
Auditing	Yes Supported starting with ONTAP 9.7	Yes Supported starting with ONTAP 9.7
Cloud Volumes ONTAP	Yes Supported starting with ONTAP 9.6	Yes Supported starting with ONTAP 9.6
Compaction	Yes Supported starting with ONTAP 9.6	Yes Supported starting with ONTAP 9.7
Compression	Yes Supported starting with ONTAP 9.6	Yes Supported starting with ONTAP 9.6
Deduplication	Yes	Yes Inline deduplication is supported on FlexCache volumes starting with ONTAP 9.6. Cross-volume deduplication is supported on FlexCache volumes starting with ONTAP 9.7.
FabricPool	Yes	Yes Supported starting with ONTAP 9.7
FlexGroup volume	Yes Supported starting with ONTAP 9.7	Yes
FlexVol volume	Yes	No
FPolicy	Yes Supported starting with ONTAP 9.7	Yes Supported starting with ONTAP 9.7
MetroCluster configuration	Yes Supported starting with ONTAP 9.7	Yes Supported starting with ONTAP 9.7
NFSv3	Yes	Yes
NFSv4	Yes	No
QoS	Yes	Yes Note: File-level QoS is not supported for FlexCache volumes.
Qtrees	Yes Supported starting with ONTAP 9.6	No
Quotas	Yes	No Note: Starting with ONTAP 9.6, remote quota (rquota) is supported at FlexCache volumes.
SMB/CIFS	Yes	Yes Supported starting with ONTAP 9.8.
SnapLock volumes	No	No
SnapMirror Asynchronous relationships	Yes	No The primary volume or secondary volume in a SnapMirror relationship cannot be a FlexCache volume. Only the primary volume of a SnapMirror relationship can be a FlexCache origin volume. Starting with ONTAP 9.8, a SnapMirror secondary volume can be a FlexCache origin volume. You can have a FlexCache volume from an origin primary volume in SnapMirror relationship, but not from a secondary volume.
SnapMirror Synchronous relationships	No	No
SnapRestore	Yes	No
Snapshot copies	Yes	No
SVM DR configuration	Yes Supported starting with ONTAP 9.5. The primary SVM of an SVM DR relationship can have the origin volume; however, if the SVM DR relationship is broken, the FlexCache relationship must be re-created with a new origin volume.	No You can have FlexCache volumes in primary SVMs, but not in secondary SVMs. Any FlexCache volume in the primary SVM is not replicated as part of the SVM DR relationship.
Storage-level Access Guard (SLAG)	No	No
Thin provisioning	Yes	Yes Supported starting with ONTAP 9.7
Volume cloning	Yes Cloning of an origin volume and the files in the origin volume is supported starting with ONTAP 9.6.	No
Volume granular encryption (VGE)	Yes Supported starting with ONTAP 9.6	Yes Supported starting with ONTAP 9.6
Volume move	Yes	Yes (only for volume constituents) Moving volume constituents of a FlexCache volume is supported from ONTAP 9.6 onwards.
Volume rehost	No	No
