TrueNAS alert message: "Failed to check for alert VolumeStatus"

[suhei]

Hi there,

I am running TrueNAS on an Intel Nuc and I get this error message in the Web GUI that I don't understand:

CRITICAL
Failed to check for alert VolumeStatus: Traceback (most recent call last): File "/usr/local/lib/python3.8/site-packages/middlewared/plugins/alert.py", line 706, in __run_source alerts = (await alert_source.check()) or [] File "/usr/local/lib/python3.8/site-packages/middlewared/alert/source/volume_status.py", line 31, in check for vdev in await self.middleware.call("pool.flatten_topology", pool["topology"]): File "/usr/local/lib/python3.8/site-packages/middlewared/main.py", line 1238, in call return await self._call( File "/usr/local/lib/python3.8/site-packages/middlewared/main.py", line 1206, in _call return await self.run_in_executor(prepared_call.executor, methodobj, *prepared_call.args) File "/usr/local/lib/python3.8/site-packages/middlewared/main.py", line 1110, in run_in_executor return await loop.run_in_executor(pool, functools.partial(method, *args, **kwargs)) File "/usr/local/lib/python3.8/site-packages/middlewared/utils/io_thread_pool_executor.py", line 25, in run result = self.fn(*self.args, **self.kwargs) File "/usr/local/lib/python3.8/site-packages/middlewared/plugins/pool.py", line 438, in flatten_topology d = deque(sum(topology.values(), [])) AttributeError: 'NoneType' object has no attribute 'values'

• Version: TrueNAS-12.0-U1
• TrueNAS is running from a USB Drive.
• Jails, Plugins (Plex Media Server) and System Data Set is located on an external HDD
• I have a 4Bay Raid connected via USB-C. It's mounted as a striped Disk Pool that contains a Dataset used for rsync Backup from a Diskstation
• There is a M.2 SSD (Windows) that is not used by TrueNAS

Can anybody help me understand the problem?

Thanks in advance.
