I have installed the latest version of truenas fangtooth on my server today (minor point release - or so I thought).
Following the upgrade I am recieving the following error messages during boot and the machine does not come online.
There has been no changes hardware wise and the machine was fresh installed with the 25.04 release with upgrades done normally through the web interface to 25.04.1 and the now 25.04.2 release.
The machine was running without any issues before the upgrade attempt.
I do not have the exact model numbers etc of the MB etc but I can confirm that the system has the following specs:
Intel i7 11th gen
68GB Ram
5x 3TB sata drives (data pool)
1x 512GB nvme (apps and config)
1x 1TB nvme (vm passthrough)
1x 250GB ssd (os drive)
Not sure what other information might be needed.
Boot to previous boot environment, 25.04.1. You can try deleting the 25.04.2 boot environment and trying the upgrade again.
68 GB Ram, is that a mistake?
Sorry 64GB (typing on the phone is a little wonky)
I have tried both boot environment options and they both give exactly the same error.
I can attach screenshots as well for the precious environment, but its the same
I think your boot device may have died if you can’t boot to a previous version. Other issues could be RAM or CPU. You would boot a live Linux USB and run CPU stress tests and a RAM test like Memtest86+
You can try powering down and reseat RAM also.
Do you have a recent backup of the system configuration file? You can try downloading 25.04.2 ISO, image to USB and use that to boot and do a fresh install. Then you reload the configuration.
Maybe it’s just not my day but I am struggling to find a proper guide on using the tar file to restore my system on the new boot drive installation.
I have the pumba-25.04.1-20250804144720.tar file as provided to me before the update (it does include the secret seed also).
And once I do a fresh install, how do I restore the tar file?
Apologies if this is documented clearly somewhere I don’t seem to find the instructions, is there perhaps a link you can share?
Do I just “Upload” on this screen? => Managing the System Configuration | TrueNAS Documentation Hub
