Rquota client space reporting between v1 and v2

[SKYYInfusions]

Hi Rquota team,

It seems like in rquota v1 there was an arbitrary limit on the quota limit when it was unlimited. ~16 TB. With rquota v2 that appears to have changed, but was something implemented for when space goes over 16TB?

Example, if over 16 report 32, if over 64 report 128?

ex:

Disk quotas for user username (uid 1000):
Filesystem space quota limit grace files quota limit grace
10.63.99.35:/nfstest
54360M 16384G 16384G 3244 4295m 4295m

quota -fs /mnt/nfstest
Disk quotas for user username (uid 1000):
Filesystem space quota limit grace files quota limit grace
10.63.99.35:/nfstest
52075G 65536G 65536G 280m 4295m 4295m

Hi @SKYYInfusions thanks for submitting the issue.

I'm not sure what you're asking, unfortunately. Are you saying you observe that rquota is reporting a quota limit when no quota is set on the underlying file system? Or are you asking if there is some way to configure a limit within the rquota config file, so the user gets a warning even if no quota is set on the underlying file system?

Correct.

When a quota for a user is unlimited, rquota will show a limit.

Previously in rquota v1, this "limit" was always 16TB. Since v2 we've seen that this has changed and the limit will change based upon how much space is used. I am just trying to determine how this arbitrary limit is determined and how it increments. I'm trying to repro it myself, but it proves hard filling multiple TB on a single client.
