Display usage of aggregate

YXMRETK

hi

 

We are currently building an OEM product for NetApp FAS 2720.

I created one volume with Type RW and one volume with Type DP (for Snapmirror) from the aggregate.

however,
When I checked the usage rate of the aggregate with the following command, it seems that only the volume of RW is written in the usage rate.

aggr show

12 entries were displayed.

 

That is aggr1_1 and aggr1_2.
This wasn't the case before, but did the notation change due to different versions?
Or is there something wrong with the volume you created?

 

The detailed version is as follows.

 

ONTAP: 9.9.1P5
FAS model number: FAS2720

Maybe you have some thin provisioning?

 Check this:

 

set diag

 Vol show -fields space-guarantee, size , used, avail, type, aggregate -sort-by volume, vserver, aggregate

 set admin

 

if guarantee : none =  thin volume = thick

Thank you for your answer.

When I checked it, it was exactly what you pointed out.

The space-guarantee setting was none.
When I changed the setting value from none to volume, it became the expected Aggregate usage rate.

Please tell me one point.

The volume for which the space-gurantee setting was none is the volume for Snapmirror.

When creating a volume for Snapmirror, only parameters such as svm, size, type (DP), aggregate are set.

I used to think that this didn't happen, but has it changed depending on the version of ONTAP?
(I'm sorry if I misunderstood ...)
