[SOLVED] Permissions on external local storage

Server
,
1

I’m facing a problem when adding a folder as an external local storage. The problem is the same as here and here where a red square and message pops up. The message is this one

An error occurred while adding the external storage, please check the logs or contact the administrator

and if click the red square

An error occurred while loading external mount point: Local

neither did this solution help (The same literal question was asked on this forum, but can’t find it)

Steps to reproduce

  1. Create a folder, chown it to www-data (both user and group) (also tried www-data:root with the same result)
  2. Enable local mount in config.php
  3. Add it to external local storage in admin settings

Expected behaviour

The mount should be added

Actual behaviour

The mount is not added, rather, an error message is thrown

I’ll reply here because I found a solution by reading another post (this one). The problem is that I was giving a local path (local to the machine) and since my owncloud instance is running in Docker, it can’t see the machine’s filesystem, so I successfully did the following:

  1. Add the folder I want to use as external storage as a volume mount on the owncloud’s docker-compose file
  2. Use the mounted path as the argument for the Local storage

Maybe this sounds dumb or obvious but posting here will probably help a desperate soul like me
