Hello all, 

my answer comes a little late but, to avoid breaking odoo after moving the filestore, you must specify the new path in the odoo configuration file in the data_dir parameter as following.

data_dir = /new/path/filestore

Hello,
maybe it will help you.
you can apply below command for MOVE Filestore Directory in a Server.
in your case :

==> sudo mv /home/odoo/.local/share/Odoo/Filestore /srv/ -R

after that you need to restart your Odoo Server Service from Ubuntu Server and check in Browser so you check your all attachments and Icons are display well in Odoo WEB Screen. 

Thanks.
