Failed retreiving GROUP quotas

[jspfunk]

First, I did google the error and have been trying to figure it out before I posted.

I'm not sure what change caused the issue. Recently changed my Plex pool from the default (Generic) to SMB. At the same time I tried to create a VM. I did get a permissions error after I went through all the setting for the VM. I think I need to add libvirt permissions to the folder I keep the ISO for Linux.

Now when I go the the Plex pool, I do not see all the folder (I have attached screen shots of what I see in Plex under Datasets and My Windows File Explorer). In Windows I see all the folders and have full permissions. when I try to open the folder "Movies" I get the in the error screen shot.

I'm not sure what change caused the error, changing the ACL type or creating the VM.

This is the More Info on the error.

middlewared.service_exception.CallError: [EFAULT] Failed retreiving USER quotas for Plex/Files/Media/Movies

. At the same time I tried to create a VM. I did get a permissions error after I went through all the setting for the VM. I think I need to add libvirt permissions to the folder I keep the ISO for Linux.

Yes if you want to point to an existing location libvirt needs to have ACL access to that path.

For the rest I have a theory. First of all, I stumbled upon the error [EFAULT] Failed retreiving USER quotas myself when I upgraded to cobia. If I remember correctly it was after initial installation and setting up all datasets / smb shares. I would be 95 % sure this is not a problem. I did need to reboot the servers anyway and since rebooting I didn't encounter that message again on either machine. I didn't have time / a spare machine to further test that theory. Although it probably it isn't, in my book I just marked it as a GUI error. It didn't have any impact for me and after rebooting it went away. What version are you on?

What I'm not sure about is the following: Is a child dataset really visible when the parent dataset is mapped via SMB?

If I got you right you got the datasets confused in GUI. The GUI will only show you the datasets (hence my previous question). You cannot browse the contents of the datasets in the truenas GUI like you can in windows.
I'm lacking the understanding to correctly explain in detail, but basically you have datasets and these datasets can contain all your directories and folders. Truenas however will only display the dataset level in the GUI. You should be able to browse them via the shell though. This also means that yes, while you cannot view the contents media in the gui you should be able to create a smb share for /plex/files/media/AtomFX for example.
I guess someone else can / will explain this better.

@chuck32 thank you for you reply. I forgot I got lazy and did not make the other folders datasets. I just updated to TrueNAS-SCALE-23.10.1.3 right before I posted this to see if maybe it was an issue that was fixed in the new release. I have rebooted a couple of times since first receiving the error, and I am still getting the error on the Movies folder

 

[chuck32]

Mmh, then maybe it was an unresolved SMB / ACL I coincidentally sorted out before rebooting. I don't know for sure.

What is your ACL setup like? Did you apply permissions recursively? You don't *need* to make a separate dataset for every directory.
Make a movie dataset, mount it via smb and be work from there. In my books there's really no need to be able to see every directory as a dataset in the GUI.

I just checked, child-datasets show up on the parent SMB share. My best idea would be that probably

Recently changed my Plex pool from the default (Generic) to SMB.

this triggered a change in your permissions and that you did not (my install prompted me to go to ACL manager when I created the child dataset) apply correct permissions to your child datasets. From your post I would assume that you can access Movies from windows.

Please post your ACL for files, media and also for movies. Maybe this will give us some idea, I assume there will be a difference. Or you could verify that movies and downloads both are of the same type as plex (SMB in that case). Assuming there are no different permissions intended on your side, you could strip ACL for the child datasets and configure them the same way as you configured your parent dataset. I don't really work with child datasets though, so I don't have much experience in how they inherit the parent dataset ACL. I could image this can resolve the issue, maybe reboot afterwards to make sure.

Otherwise you should maybe create a jira ticket if you believe this behaviour is a bug.

@chuck32 I have attached screen shots of my ACL for each folder. I am not sure if there is an way to show you my ACL's. I did strip all the ACL's from all the folders and set up Files ACL's and made it recursive and applied them to all child data sets. I still get the error and only on Movies.

 

[chuck32]

I have a last idea. When you recreate the ACL, do that again and use a preset (restricted for example). You deviate a lot from the default config.

Usually it is ower = root, owner group = root (you may need to set that separately and probably before setting a new ACL with a preset, when you strip the ACL and use a preset, I'm not sure this will be changed automatically).
The preset should include access for owner@ - root, @owner - group, builtin users and builtin admins. This will be done by using the preset. Then manually add your user / group.

My assumption is, since you are root / admin in the GUI and you don't have permission, that this will lead to the error.

This is what my default settings look like and what I meant to describe above:
