Files external

These commands are used for managing Nextcloud’s External Storage feature. In addition to replicating the configuration capabilities in the Web UI, additional capabilities include exporting / importing configurations, scanning External Storage mounts that require login credentials, and configuring update notifications (if supported by the storage type).

Note

These commands are only available when the “External storage support” app (files_external) is enabled.

Available commands for the “files_external” namespace:

files_external:applicable  Manage applicable users and groups for a mount
files_external:backends    Show available authentication and storage backends
files_external:config      Manage backend configuration for a mount
files_external:create      Create a new mount configuration
files_external:delete      Delete an external mount
files_external:export      Export mount configurations
files_external:import      Import mount configurations
files_external:list        List configured admin or personal mounts
files_external:notify      Listen for active update notifications for a configured external mount
files_external:option      Manage mount options for a mount
files_external:scan        Scan an external storage for changed files
files_external:verify      Verify mount configuration

files_external:scan provides the ability to provide a username and/or password for cases where login credentials are used.

Use files_external:export to export all admin mounts to stdout, and files_external:export [user_id] to export the mounts of the specified Nextcloud user.

Use files_external:import [filename] to import legacy JSON configurations, and to copy external mount configurations to another Nextcloud server.

Hello  I Could solve my Issue using this solution (Thanks to jtr) :

Connect to your VM (Shell Linux) hosting your NextCloud. Use SU.
Go to the Folder hosting NextCloud with the occ file. (This step should look evidence for everyone , but I am Noob hahaha, I give advices for Noob  )

And write this :

Here , you can do this :
sudo -u www-data php occ files_external:list

You can see the bad External Drives and delete it with :
sudo -u www-data php occ files_external:delete X

Then , you can re-create good ones by using this command :
sudo -u www-data php occ files_external:create Blabla ‘sfpt’ password::password -c host=X.X.X.X -c share=/X/ -c root=/X/ -c domain=workgroup -c user=X -c password=X

Replace : X with Yours 

Have a nice day
