ohhh, is this even supported ?

@icewind1991 any ideas on this one ?

szaimen · 2022-05-13T08:55:50Z

Yes it was introduced as a feature a few years ago. I can try to find the PR that added this if needed.

Problem is that if that does not work anymore it might break the whole thing for some instamces because they would need to change the external storage configuration which would mean that oc_filecache would be completely exchanged with all drawbacks that come with it.

PVince81 · 2022-05-13T09:05:15Z

I'm guessing this is related to the recent mount point performance optimizations, where we probably didn't think about this unusual kind of moint point. I suppose that the fix here would be to detect root mounts and exclude them from the "on-demand" logic and have them always resolved.

Whatnoww · 2022-05-16T07:55:49Z

Thank you for your response. I've been suffering this issue recently as well. Oddly enough there are no issues when displaying the files on the Android app and you can manually access the files by their directory name in the address bar.

syntron · 2022-05-22T19:23:12Z

I'm from [Bug]: Directory not available / Error loading data] #32541 - this seems to be the case for external data, i.e. from another computer via smb or federation. A locally mounted NFS share as external source works well.

sebabordon · 2022-05-24T23:45:27Z

Found out I have the same problem. For some reason, My Domain Admin account works well, but others do not. No issues on the log after enabling debug

vicelversa · 2022-05-25T18:59:53Z

Also running into this issue on Nextcloud 24. Here is the original PR for this feature: #3438

Note that I am using an S3 bucket as external storage mounted to '/'

peacepenguin · 2022-05-25T19:43:12Z

Running into this issue too. @sebabordon thanks for your domain admin hint. I've now found i can make the issue go away by explicitly granting permission to the SMB user on the share. For some reason this works. "BOB" - windows user configured in nextcloud external storage for the mapping, when granted "Full Control" over c:\nextcloudroots\bob now i can mount his folder as "/" like before.

Previously BOB was a member of "NextcloudRoots" local windows group, that group has Full Control of the same folder structure. In this model the "/" root mapping no longer works in v24, but mapping to "/external/" works fine. So it's not a full-on permissions issue, but somehow related to how permissions are given in Windows.

It's like the issue has to do with group membership somehow, doesn't make sense, but a workaround nonetheless for now.

Good to know it works for you!, however, my permissions on an the SMB share (Samba Home share) are granted to creator owner and the user account itself, with everyone full control as share permissions. I have been fiddling with permissions before posting a bug, so now it is properly secured but issue remains. I could try share permissions as well.

peacepenguin · 2022-05-26T13:44:48Z

I tried the explicit permissions workaround on another instance with php7.4 instead of 8.1. And the workaround does not work with 7.4. So another variable to this problem.

peacepenguin · 2022-06-06T16:28:42Z

Any update? This bug is a regression and needs fixed, otherwise the documentation needs to be updated to reflect external storage mapping to user's root '/' is now unsupported.

icewind1991 · 2022-06-09T17:25:44Z

should be fixed with #32797

Kramins · 2023-01-15T15:36:58Z

I understand this issue is closed but I am experiencing the same issue with Nextcloud 25.0.2
I can see all the files on the website however on the client and webdav, I don't see any file updates and the root folder only contains the default files from the original /data folder.
