Upgrade to FreeNAS 11: Internal Server Error

[Ingo]

After upgrading to FreeNAS 11, I got the error message "Internal Server Error" when I try to start the GUI.
How can I switch back to FreeNAS 9.10? I have access with putty to the server.

On reboot, choose an older boot environment.

Thanks for the answer. Is there an other way to analyze what went wrong. Which logfiles should I check?

Maybe, but it sounds like a botched upgrade, possibly due to the boot device beginning to crap out. If the second attempt at the upgrade fails similarly, start by replacing the boot device and we'll work from there if the problem persists.

When in doubt, run "freenas-update -v update" from the shell, and it will include all sorts of output that is useful to, uh, me, anyway. :)

Sometimes when doing an update via the GUI, something times out and interrupts the update process, but after it has created the new boot environment, and possibly applied some of the packages. No clue why unfortunately, and I've never been able to reproduce it.

It looked like that my first update was incomplete. I reinstalled FreeNAS11 again and noweverything is fine. Many thanks for helping.
