There is a folder which I can't delete. Also indexing is broken

Glowing_Wolf · July 13, 2023, 12:49pm

Nextcloud version (eg, 20.0.5): 27,0,0,8
Operating system and version (eg, Ubuntu 20.04): Debian 11
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.56-1
PHP version (eg, 7.4): whatever th image uses
I host using docker-compose and the official image.

The issue you are facing:
I have a folder “music” which just causes an error message when trying to delete it. I already cleared the locked files table and restarted my db as well as my nc container while in maintenance mode.
I am running nc hub 4 on debian 11 via a docker stack running rough portainer and the files are stored in a contabo object storage (s3).

I have two accounts.
On both accounts I hav a folder with the same name.
On acc one, the folder is filled. On acc two its empty.
The folder on acc one is alerady shared with acc two.
I tried changing the owner of the folder of acc one to acc two. After accepting the ownership change on acc two, nothing happend.
I tried deleting the still empty folder on acc two. That didnt work
I tried stopping the share on acc one. That didnt work.
I tired opting out of the share on acc two. That worked!
I tried deleting the folder on acc two again with NO success.

I wanted to try to delete the file through occ but I am unsure how that works since the folders are stored in an object storage.

I’ll gladly add any missing info

PS: A lot of folders across accounts are shown with 0B in them while they are filled with data which is accessible.

Is this the first time you’ve seen this error? (Y/N): Y

It could have something to do with this bug: Can’t delete folders while the app is enabled · Issue #1068 · owncloud/music · GitHub

Much luck

Glowing_Wolf · July 13, 2023, 1:40pm

Great tip! The app was blocking the directories from being deleted. Now the only problem stays that a lot of other dirs still son’t show their file size.
How can I trigger the calculation of that? Is that something the OCC tool can do?

You can do a rescan of the entire filesystem with

occ files:scan --all

For the details, see the help:

:~# occ files:scan --help
Description:
  rescan filesystem

Usage:
  files:scan [options] [--] [<user_id>...]

Arguments:
  user_id                  will rescan all files of the given user(s)

Options:
      --output[=OUTPUT]    Output format (plain, json or json_pretty, default is plain) [default: "plain"]
  -p, --path=PATH          limit rescan to this path, eg. --path="/alice/files/Music", the user_id is determined by the path and the user_id parameter and --all are ignored
      --generate-metadata  Generate metadata for all scanned files
      --all                will rescan all files of all known users
      --unscanned          only scan files which are marked as not fully scanned
      --shallow            do not scan folders recursively
      --home-only          only scan the home storage, ignoring any mounted external storage or share
  -h, --help               Display help for the given command. When no command is given display help for the list command
  -q, --quiet              Do not output any message
  -V, --version            Display this application version
      --ansi|--no-ansi     Force (or disable --no-ansi) ANSI output
  -n, --no-interaction     Do not ask any interactive question
      --no-warnings        Skip global warnings, show command output only
  -v|vv|vvv, --verbose     Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

It looks like this doesn’t work. I assume because I use an object storage. But this is the output:
