evcc.db disappears after update to 0.131.5

[floppybl]

Describe the bug

Hi all,

after updating evcc running in docker on unraid to current version the evcc.db was deleted during the update process. Is this a known problem? And will this happen again on future updates?

Steps to reproduce

1. update docker container from unraid gui
2. after update all things setted up in evcc gui (admin password, cars etc.) are gone except of settings in yaml

You need to mount it, see https://docs.evcc.io/en/docs/installation/docker#volumes

[floppybl]

It is all correctly mounted like unraid let set the mounting points. It worked for weeks with updating from 0.131.3 to 0.131.4 without touching the database.

[arcidodo]

I have the same issue. And i also using unraid..

[StefanSchoof]

Evcc logs at the start the local path that is used. Ensure you mount the right folder.

[arcidodo]

i removed in the unraid gui the folder mount points and added this (in advanced view) into the extra parameter field:

-v /mnt/user/appdata/evcc/config/evcc.yaml:/etc/evcc.yaml -v/mnt/user/appdata/evcc/root/.evcc/:/root/.evcc/

it look like it is working now.

[GrimmiMeloni]

evcc does not delete its database during startup.
Assuming you correctly mounted the configuration and db prior to the upgrade, you should see those on the host in /mnt/cache/appdata/evcc (path taken from your screenshot above).
