Invalid cross-device link at /var/www/html/lib/private/Files/Storage/Local.php#339

[mmallejac]

Steps to reproduce

• share a folder located under a local location mounted using files_external
• using the share link, on another browser or computer, make some files and folder operations (upload, creation, delete)
• it happens on one out of 10 operations, approximately

This happens only under these conditions :

• while using a share link, as an external user
• the share link points to a folder located on a docker volume
• this docker volume is locally mounted with files_external

Expected behaviour

No error is shown

Actual behaviour

On screen : an error message appears "could not remove file ttt", then a page refresh shows expected results (that the file has been actually removed)

In nextcloud.log :

[danfate]

same issue here, do you find the solution?

[mmallejac]

Nope, sorry.
We try now to avoid files_external folders as much as possible.
We're still looking for the most appropriate way to share he same data with two different systems (Nextcloud and Samba).

Not an issue with the Docker image. This was in Nextcloud server. This repository isn't for server. :-)
