Performed an in-place upgrade within the web UI - changing train from TrueNAS SCALE ElectricEel 24.10 [release] to TrueNAS SCALE Fangtooth 25.04 [release].
i have a similar issue with HP Proliant ML310e GEN8>
When booting 24.10.2.1 ( Fresh Install) it is all ok
When booking 25.04.0 (Fresh install) I get middleware unable to start
I had no problems when I updated to 24.10.2. I had a problem once I tried to get to 25.04. I have been informed that there are a lot of changes to the middlewared startup coming in the next 25.04 release (due 5/27/2025).
In the mean time, you could try to delete or rename fhe files in /audit and then doing the upgrade to 24.10.2
