Move datadirectory

If you wish to change the data location, after running Nextcloud for a while, you need to make several changes:

Run occ commands as the system user that owns the Nextcloud files su - www-data -s /bin/bash

Set Nextcloud in maintenance mode

cd /path/to/nextcloud/
php occ maintenance:mode --on

Move the datadirectory from the current to the new location

The webserver must have access to the new datadirectory location
Update datadirectory in config/config.php

Update the oc_storages old datadirectory entry.

Just changing the config/config.php will add a new local::/path entry in oc_storages and Team folders will not show the files anymore

select * from `oc_storages` where id like 'local::%';
+------------+----------------------------+-----------+--------------+
| numeric_id | id                         | available | last_checked |
+------------+----------------------------+-----------+--------------+
|          2 | local::/var/www/html/data/ |         1 |         NULL |
+------------+----------------------------+-----------+--------------+

update `oc_storages` set id='local::/data/' where numeric_id=2

Run occ scan commands to update database references

cd /path/to/nextcloud/
php occ files:scan --all
php occ files:repair-tree
php occ groupfolders:scan

Remove Nextcloud maintenance mode

cd /path/to/nextcloud/
php occ maintenance:mode --off
