Individual storage space usage

trackstar — Wed, 04 Jun 2025 09:56:07 GMT

Hello,

Is there a way to view individual disk space usage on the volume?

We are on the following:

FAS2650 with 2 nodes. Version NetApp Release 9.3P18.

Thanks,

No. You don't need to. ONTAP splits the raid stripes evenly across the aggregate. The only time it isn't even is if disks are added without a reallocate. https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/What_are_the_best_practices_for_adding_disks_to_an_existing_aggregate%3F

Sorry my question isn't clear. I want to know how many GB of storage space JohnDoe uses on Volume1.

Ah. File System Analytics on 9.8+ or quotas will give you what you want. There may be other methods, but those are the first two to come to mind.

I see. We only have quota turned on for one volume. Its been a while, but if I turned quota on for existing volumes the size would be enforced immediately and the processing consumption will go up? Not sure if I want to turn on the quota just for this report.

Default quotas can be tracking quotas.

quota reporting and quota enforcement are related but you don't need quota enforcement for what you're trying to do. We turn on quota reporting on EVERY volume as part of the volume creation process.

quota policy rule create -vserver $vserver -policy-name $policyname -volume $volume -type user -target "" -qtree ""
quota on -vserver $vserver -volume $volume

Wait for the quotas to be calculated and then:
quota report $volume
either search for the user manually or add the options to report on only that user

for added enjoyment, go into diag mode and add -sort-by disk-used
this will sort the list so your biggest consumers are listed last. It still surprises me that sort-by is only available in diag mode...

I just took a look again and all the production volumes have default quota on (Activate with the green dot on Quota Status on Volume tab)

This commands works:

volume quota report -vserver vs0 -volume vol1 -quota-type user

But when I added the username in it failed with Error: "quota-target" is an invalid value for field "-index <integer>"

volume quota report -vserver vs0 -volume vol1 -quota-type user -quota-target john

I am referencing this link:

What was the error message?

Re: Individual disk space usage

trackstar — Wed, 26 Oct 2022 17:31:12 GMT

Error: "quota-target" is an invalid value for field "-index <integer>"

Sounds like a typo or you're missing a field -index in your command.

You are quick! Yes I was missing "-" before the quota target command.

I am using putty. Lets say I run this command below and it shows your typical result (need to press enter or space bar to view next entry/page). Is there anyway to write this into a file?

volume quota report -vserver vs0 -volume vol1 -quota-type user

I am aware of the logging. My question wasn't clear.

I meant of writing a csv file output but I guess it won't be allowed under the user agreement. Thanks for your help though. Appreciated it!
