It is not possible to change datadirectory easily on an existing installation as various databases hashes and paths need to be updated. However, for a new owncloud installation (Tested on bitnami ownloud 10.6.0-2) we can change data directory using:

1. Create folder for data directory. This could be an LVM mount point. For example /mnt/files

   mkdir /mnt/files   #Or mount <lvm-device> /mnt/files

2. Change the ownership on this folder to daemon:daemon

   chown -R daemon:daemon /mnt/files

3. Move existing data directory files to this location

   cd /opt/owncloud-10.6.0-2/apps/owncloud/data
   mv * /mnt/files
   mv .* /mnt/files  #Important to move .ocdata and .htaccess files

4. Update '/opt/owncloud-10.6.0-2/apps/owncloud/htdocs/config/config.php' with the new path

   'datadirectory' => '/mnt/files',

5. Log into database using credentials from the above config file using '/opt/owncloud-10.6.0-2/mysql/bin/mysql -u root -p' and do following changes
   1. Check oc_accounts table

      select * from oc_accounts;

   2. If admin data folder is pointing to older path and not to updated /mnt/files then use following:

      update oc_accounts set home = '/mnt/files/admin' where user_id='admin';

6. Now scan for changes for all paths using

   cd /opt/owncloud-10.6.0-2/apps/owncloud/htdocs
   sudo -u daemon /opt/owncloud-10.6.0-2/php/bin/php occ files:scan --all

7. Upload a small test file to admin user and check contents of /mnt/files/admin/files folder to see if the new uploaded file is available there.
