Hi,
Does this help you?
Following should list all the users:
cluster1::>volume quota report -thresholds
cluster1::>volume quota report
I guess, if you supply -target-ID 'username', it should give user details: Command may vary a bit depending upon your Ontap version, so just check the doc link provided below.
cluster1::>volume quota report -target-id 'user'
If you need to provide more space in volume vol1 to the user, then you enter the following command:
Explicit user quota overriding a default user quota (Increase)
::>volume quota policy rule create -vserver vs1 -policy-name default -volume vol1 -type user -target username -disk-limit 80MB -qtree ""
Try this command to modify user quota (Increase):
::>volume quota policy rule modify -vserver vs1 -policy-name default -volume vol1 -type user -target username -disk-limit 80MB -qtree ""
Examples of quota configuration

Note: You must ensure that you wait for about five minutes before reactivating the quotas on each affected volume, as attempting to activate them almost immediately after running the volume quota off command might result in errors.
Thanks!
