Cannot modify autogrow value

Kiko — Wed, 04 Jun 2025 09:51:52 GMT

I'm configurig new volumes in Ontap 9.12.1 with commands.

I indicate these parameters:

-size 10TB -security-style unix -space-guarantee none -max-autosize 10.5TB -autosize-grow-threshold-percent 90 -autosize-mode grow

But when the volume is created the autogrow size I find it in 12TB What could be the reason?

Thanks

I don't have 9.12.1 to verify it but it seems it has taken the default 120% of the volume size as 'max-autosize' value. Are you not able to modify it ? vol modify -volume <volume> -max-autosize 10.5T ?

You could also just raise a ticket with NetApp to get this clarified.

It's funny but this only happens to me in a metrocluster IP system.

In a standard AFF storage the result of the command is as expected.

I'll open a support case to see what they can tell me.
I'll update this post with the result.

Thanks for sharing this info. I see, so it's happening specific to MetroCluster system, that's interesting. Sure, do let us know the result.
