The issue you are facing:
I uploaded folders with movies via web browser to my Nextcloud server. During upload there was some error.
I tried to remove folders and movie.mkv file (7.5 GB) but I received error that the file cannot be removed. (Error during deleting file)
So I logged in my Ubuntu server and I edited Movie folder as I needed (root user) via SSH (terminal).
I restarted SNAP (also tried restart Ubuntu server) but there is the problem.
I see folders and files that no longer physicaly exists on disk drive via web brovser.
So I like to know how to rescan whole file structure via Nextcloud to fix this issue.
Is this the first time you’ve seen this error? (Y/N): Yes
Steps to replicate it:
- Files uploaded via web browser - problem during upload
- SSH connection via terminal and set folder structure as needed
- Web browser see files that no longer exist.
