Creating your file...
You can automatically provision a FlexGroup volume. ONTAP creates and configures a FlexGroup volume by automatically selecting the aggregates. Aggregates are selected based on the best practices for optimum performance.
Each node in the cluster must have at least one aggregate.
For creating a FlexGroup volume for FabricPool in ONTAP 9.5, each node must have at least one aggregate that is FabricPool. |
ONTAP selects two aggregates with the largest amount of usable space on each node to create the FlexGroup volume. If two aggregates are not available, ONTAP selects one aggregate per node to create the FlexGroup volume.

Provision the FlexGroup volume:
If you are using…
Use this command…
ONTAP 9.2 or later
volume create -vserver svm_name -volume fg_vol_name –auto-provision-as flexgroup -size fg_size [–encrypt true] [-qos-policy-group qos_policy_group_name] [-support-tiering true]
Beginning with ONTAP 9.5, you can create FlexGroup volumes for FabricPool. To automatically provision a FlexGroup volume on FabricPool, you must set the
-support-tiering
parameter totrue
. The volume guarantee must be always set tonone
for FabricPool. You can also specify the tiering policy and tiering minimum cooling period for the FlexGroup volume.Beginning with ONTAP 9.3, you can specify a throughput ceiling (QoS Max) for FlexGroup volumes, which limits the performance resources that the FlexGroup volume can consume. Beginning with ONTAP 9.4, you can specify throughput floors (QoS Min) and adaptive QoS for FlexGroup volumes.
Beginning with ONTAP 9.2, you can set the
-encrypt
parameter totrue
if you want to enable encryption on the FlexGroup volume. For creating an encrypted volume, you must have installed the volume encryption license and the key manager.You must enable encryption on FlexGroup volumes at the time of creation. You cannot enable encryption on existing FlexGroup volumes. ONTAP 9.1
volume flexgroup deploy -vserver svm_name -size fg_size
The
size
parameter specifies the size of the FlexGroup volume in KB, MB, GB, TB, or PB.The following example shows how to provision a FlexGroup volume of size 400 TB in ONTAP 9.2:
cluster-1::> volume create -vserver vs0 -volume fg –auto-provision-as flexgroup -size 400TB Warning: The FlexGroup "fg" will be created with the following number of constituents of size 25TB: 16. The constituents will be created on the following aggregates: aggr1,aggr2 Do you want to continue? {y|n}: y [Job 34] Job succeeded: Successful
The following example shows how to create a QoS policy group for throughput ceiling and how to apply it to a FlexGroup volume:
cluster1::> qos policy-group create -policy group pg-vs1 -vserver vs1 -max-throughput 5000iops
cluster-1::> volume create -vserver vs0 -volume fg –auto-provision-as flexgroup -size 400TB -qos-policy-group pg-vs1 Warning: The FlexGroup "fg" will be created with the following number of constituents of size 25TB: 16. The constituents will be created on the following aggregates: aggr1,aggr2 Do you want to continue? {y|n}: y [Job 34] Job succeeded: Successful
The following example shows how to provision a FlexGroup volume of size 400 TB on aggregates in FabricPool in ONTAP 9.5:
cluster-1::> volume create -vserver vs0 -volume fg –auto-provision-as flexgroup -size 400TB -support-tiering true -tiering-policy auto Warning: The FlexGroup "fg" will be created with the following number of constituents of size 25TB: 16. The constituents will be created on the following aggregates: aggr1,aggr2 Do you want to continue? {y|n}: y [Job 34] Job succeeded: Successful
The FlexGroup volume is created with eight constituents on each node in the cluster. The constituents are distributed equally between the two largest aggregates on each node.
By default, the FlexGroup volume is created with the
volume
space guarantee setting except on AFF systems. For AFF systems, by default the FlexGroup volume is created with thenone
space guarantee. -
Mount the FlexGroup volume with a junction path:
volume mount -vserver vserver_name -volume vol_name -junction-path junction_path
cluster1::> volume mount -vserver vs0 -volume fg2 -junction-path /fg2
You should mount the FlexGroup volume from the client.
If you are running ONTAP 9.6 or earlier and if the storage virtual machine (SVM) has both NFSv3 and NFSv4 configured, mounting the FlexGroup volume from the client might fail. In such cases, you must explicitly specify the NFS version when mounting the FlexGroup volume from the client.
# mount -t nfs -o vers=3 192.53.19.64:/fg2 /mnt/fg2 # ls /mnt/fg2 file1 file2
