The root cause is that the `FILEBROWSER_DATABASE` environment variable is not overriding the default database path as expected (logs consistently show creation of "database.db" at the default relative location `./database.db`, implying the env var is ignored or ineffective in this version/context). The default path resolves to the container's working directory (/home/filebrowser/database.db), which is not part of the persisted volume mount (only /home/filebrowser/data is mounted). Thus, the database is created ephemerally in the container filesystem and lost on restart, triggering recreation and user reset.
This behavior holds despite docs listing `FILEBROWSER_DATABASE` as supported (equivalent to `server.database`); in practice, for v1.1.0-stable, configuration via config.yaml takes precedence and works reliably. Permissions match (container user 1000:1000 aligns with host umbrel:umbrel UID/GID), and the mount is writable (evidenced by config.yaml presence), so no issue there.
### Fix (First-Principles, Verified via Docs)
Update `~/umbrel/app-data/my-filebrowser-quantum/data/config.yaml` under the `server:` section (add if missing):
```yaml
server:
# ... existing entries like port: 80
database: "data/database.db" # relative to WORKDIR /home/filebrowser; resolves to mounted /home/filebrowser/data/database.db
```
- Remove `FILEBROWSER_DATABASE` from docker-compose.yml (redundant/ineffective).
- Optionally, change `FILEBROWSER_CONFIG` to relative `"data/config.yaml"` for consistency with upstream examples, though absolute works.
- Restart the app via Umbrel dashboard or `~/umbrel/scripts/app restart my-filebrowser-quantum`.
- Verify: After restart, check host `~/umbrel/app-data/my-filebrowser-quantum/data/database.db` exists (BoltDB file, ~10-20KB initially). Logs should no longer warn about missing DB or create a new one. Users persist.
This persists the DB via the existing volume, avoiding custom mounts or UID tweaks. If still fails (e.g., no file created), test writability by adding a dummy command in compose (e.g., touch /home/filebrowser/data/test.txt) and inspect logs.
De vorige keer dat ik hier aan wijzigde vanaf deze staat was om het probleem op te lossen dat na server herstarts steeds een nieuwe database werd gemaakt en de users daarom verdwenen waren
