Is it possible to use OnCommand to provisioning a new volume and share/export the volume - not a qtree below the volume?

serik — Thu, 05 Jun 2025 06:57:09 GMT

So basicly I want to use Provisioning Manager to provisioning a NAS volume, where the new dataset is a new volume without any qtree's in the volume.

I would like to share/export the volume itself, not a qtree below.

I've found that I can set "maxQtreesPerVolume" to one, but I still get a qtree below the volume.

Any help appreciated.

regards Erik

Hi Erik,

Today the product doesn't allow creation of volumes for NAS with exports.

It always creates qtree with/without exports.

One way I can think to achieve this is by using a SAN policy(volume creation)

And adding the exports or shares for the volume using post provisioning scripts.

But the volume properties will be optimized for a SAN container.

Otherwise set the max qtrees per volume as 1 and create a qtree with as large as the required volume size.

Latter in the post provisioning script delete the qtree its quota,share/export and then add export or share for the volume.

I know it a round about way, but this is what I can think off to achieve this.

Just curious as to why you want NAS volume provisioning instead of qtree ?

Hi and thanks adai

Actually this is a request from a long time NetApp customer. They used to have qtree shares/exports, but now they want to avoid the qtree level (or they just dont use qtrees because they see no need for them).

They have few, but large volumes (appr 2-6TB) and I actually don't know why they want to avoid qtrees - but resizing might be an issue.

They are currently not using OnCommand, but are feeling the pain in all the manual steps necessary to set up a volume, configure protection (using VSM) and configuring the CIFS/NFS share parameters.

I feel that the possibility to provision volumes without qtrees and setting the nos qtree per volume should be integrated in the GUI in an upcoming version.

Hello Erik

@ and I actually don't know why they want to avoid qtrees - but resizing might be an issue.

Provisioning manager provides very easy resizing mechanism for both Qtrees and Volumes. So if its a problem here, we have some useful solution.

Having a Qtree doesn't have any disadvantage that one might want to avoid it. It just allows an extra parameter that user may use ( or not if he/she wishes otherwise).

Here is the way to set it,

[root@lnx186-88 ~]# dfm option set maxQtreesPerVolume=20
Changed maximum qtrees per volume to 20.

It's a hidden option. By default it will be having the value as 15. Once user changes it then it will be shown in the "dfm option list" output
