Hello, i found the following bug in the current Truenas Core 12 Beta 2.
The WebUI just shows a empty table that normally would show the topology of the pool.
i looked ad the websocket traffic and there the following message came in:
it worked in 11.3 with the same pool topology
My guess is that this has something todo with the indirect vdev that is a leftover from the removal of a top level vdev (fairly new feature)
