Volume filesystem stuck at 879 MB despite dashboard showing 5 GB — "Live resize" not taking effect

Question

I have a volume attached to a Streamlit web service. The dashboard shows the volume size as 5.00 GB, and I've clicked "Live resize" multiple times, but the actual mounted filesystem remains at only 879 MB.

**Setup:**

* Service: Streamlit web app (Nixpacks build, Python 3.13)
* Volume mount path: `/data`
* Volume region: EU West (Amsterdam, Netherlands)
* Dashboard configured size: 5.00 GB

**How I verified the actual filesystem size:**

I added this diagnostic code to my app startup:

```
python
```

```
import shutil
```

total, used, free = shutil.disk\_usage("/data")

print(f"Volume: {total/1024/1024:.0f} MB total, "

f"{used/1024/1024:.0f} MB used, {free/1024/1024:.0f} MB free")

**App logs after latest deploy:**

```

```
[diag] Volume: 879 MB total, 863 MB used, 0 MB free
```

$$diag$$ DB file: 840.4 MB

$$diag$$ WAL file: 15.9 MB

As you can see, the filesystem reports **879 MB total** \-> not the 5 GB configured in the dashboard. With an 840 MB SQLite database, this leaves 0 MB free and all write operations fail with `sqlite3.OperationalError: database or disk is full`.

**Steps taken:**

1. Set volume size to 5.00 GB in dashboard settings
2. Clicked "Live resize"
3. Redeployed the service
4. Verified via `shutil.disk_usage()`, still shows 879 MB total

**Expected:** Volume filesystem should be 5 GB (or close to it) **Actual:** Volume filesystem is stuck at 879 MB

Has anyone experienced this? Is there an additional step needed to make the resize actually propagate to the filesystem? Any help appreciated!
