Quota warning mail sent to all users on full data storage disk

[hostingnuggets]

Hello,

The disk on my server where I have the storage directory (Nextcloud "data" directory) got full and this triggered the quota warning mail to be sent to all my users. None of these users where actually using their whole quota. I think this is a mistake and this app should have not sent any quota warning mails.

I am using Nextcloud 13.0.5.

unfortunately that is nothing I can really detect, because the user quota is capped with that one too...
So if there is no disk space left your user quota is limited to the available disk space.

@nickvergessen thanks for your quick answer. I see the issue... maybe a "dirty" workaround such as checking the disk space available through the OS (df on Linux) beforehand might do the job? For instance if the OS reports that it is 100% full no quota warnings should be sent at all just to prevent this case.

I know this is an old issue (and I guess it is more like an enhancement request) but I'm encountering the same question ... I guess a smarter solution could be:

• no more parameter screen for individual users
• one parameter screen for admins with a list of users with their individual quotas (as entered in user setup)
• an additional field to enter a global quota (because getting OS info might be tricky depending upon system, environment, ..)
• warnings by notifications or email to admins (in my opinion a global value like 90% for individual or global quota is enough, so just one field to enter the warning threshold)
• when a user quota or the global quota is reached, email to admin and notification
  Thanks for listening !
  Pierre.

This got me really confused - but apparently for me happened the same, my storage disk filled up - but instead of everyone getting the email - random people were getting it

Is there any progress on a fix?

There are simple PHP API's for it:
https://www.php.net/manual/en/function.disk-free-space.php

And perhaps compare it against the giving threshold and total free/used ratio:

No

That makes several assumptions on the architecture of the system

Isn't there a view in the Nextcloud admin interface that shows storage usage on the file system?
Maybe it would be possible to access that data point or use the same approach to get the information.
