I’m getting the “the system found unauthorized changes on the firmware, operating system or UEFI drivers” when I attempt to boot.
Forcing my way into the BIOS, I find all the drives I expect (6 6TB data drives, two SSD drives one of what is boot and one of which was intended to be a cache drive but that never quite happened).
Booting from either of the SSD drives I get “This is a FreeNAS data disk and can not boot system. System Halted.”
My latest config backup says it’s of TrueNAS-13.0-U5.3. I’m reasonably sure that’s essentially current, haven’t added users or changed pools in some time.
I can of course try booting truenas or other OS from USB, and just try reinstalling (since I have the config backuip).
Is that likely to be my smart course? Is the motherboard config RAM battery likely to be the problem? Can I maybe reinstall in place and preserve the config info? What are my big dangers when I start clumsily poking my fingers into things?
My usual problem – I only run this one TrueNAS server, and it runs flawlessly for so long that I forget the details, not practicing them every week or month.
No reason to suspect any damage to the data set so far, at least. It’s annoying but not really serious for it to be out of service for days or even a few weeks (home environment).
