"Physical Security Chassis Intru Asserted General Chassis intrusion" after updating?

[EvanVanVan]

Hi, yesterday I upgraded to TrueNAS-13.0-U4 and when it restarted it had six alerts stating "Physical Security Chassis Intru Asserted General Chassis intrusion ()." I googled it but did not find much information that seemed to apply.

FWIW, I am at 81% storage space usage and also have an alert that for optimal pool performance space usage should be under 80%. I'm looking into getting more hard drives and adding a second pool.

Any suggestions on what the issue is?

Thanks

Your BIOS probably has a chassis "intrusion detection" sensor (basically a switch that's tripped when the case is opened).

A recent update of TrueNAS seemed to pick up more warnings than previous versions from BIOS/FAN logs, so maybe it has been tripped for a long time (or whenever you opened the case last) and you just had no report of it.

Thank you, that's probably exactly what is. I'll take a look on how to reset it.
