Set the snapshot capacity to 0 GB, but why does the snap reserve used have capacity?

Hi, All

 

I am studying about FAS. I apologize for the frequent questions.

While checking the volume of the FAS equipment installed in the customer, I checked the following information through the df command.

As you can see in the photo above, you can see 3427GB in the snap reserve used space at / vol / vol1.
 
 
However, when I checked the snapshot through the snap list -l command, I could see the message that it does not exist.

When I check the volume with the vol status -S command, it is as follows.

Here are my questions.
 
1. Why does the snap reserve space total 0GB, but does 3427GB come out as used?
2. Why is it that there is a used capacity, but there is no snapshot?
3. If i don't need it, how to clear that snap reserve?
 
 

Please answer..
If you need additional information, please reply. I'll upload it.

 

Thank you.

(Since i used a translator, the sentence may not be smooth.
Please tell me any sentences you don't understand.)

1. why do you use option -l with snap list command?

https://library.netapp.com/ecmdocs/ECMP1114237/html/man1/na_snap.1.html

snap list -l [ vol_name ]
For each of the snapshots of a volume, this command displays the date the snapshot was taken along with the SnapLock retention date for the snapshot. 

 

I assume you don't have any snaplock here

 

2. Here are few links for you about the snap reserve

Try a snap list -n.
