ONTAP cluster, aggregates and network share common space

Lukas2 — Wed, 04 Jun 2025 09:59:57 GMT

Hello everyone,

I'm new to forum and ONTAP and I've a question.

Were're running on two node ONTAP cluster. From CLI I was able to create aggregates (one per node), root volume, SVM etc., but when it comes to creating SMB share I can only see space of single aggregate and I'm not able to add storage space of another.

Is it possible to create common/shared aggregate for two nodes?

If not, how it's possible to create network share and use space of two aggregates at once?

Thanks & regards!

Volume junctions function to join individual volumes together, into a single logical namespace, in order to enable data access to NAS clients.

What are junction paths?

another way will be to create a flexgroup.

Hi,

can you please clarify additional thing? I've created:

volumeA on nodeA and mounted it under /path

volumeB on nodeB and mounted it under /path/B

I couldn't 've used /root path for volumeB or mount volumeA under /path/A, if it matters.

This share is intended to be a NAS, but currently I cannot use whole capacity, only half of it.

How junction should be used to combine aggregates and share it as a single storage space? If not possible with aggregated and junction, how then?

regards,

Maybe Flexgroup is what you are looking for.

FlexGroup volumes: An evolution of NAS
ONTAP 9.1 brought innovation to scale-out NAS file systems: the NetApp ONTAP FlexGroup volume.
With FlexGroup volumes, a storage administrator can easily provision a massive single namespace in a
matter of seconds. FlexGroup volumes have virtually no capacity or file count constraints outside of the

physical limits of hardware or the total volume limits of ONTAP. Limits are determined by the overall
number of constituent member volumes that work in collaboration to dynamically balance load and space
allocation evenly across all members. There is no required maintenance or management overhead with a
FlexGroup volume. You simply create the FlexGroup volume and share it with your NAS clients. ONTAP
does the rest.
