Upgrade from 9.29 to 9.3 - Stuck at GRUB

[ssvt]

I've got a Freenas installation that was working properly. (64bit Intel box, 8g of ECC ram, ZFS pool, been working for over a year with no issues.) I attempted a gui upgrade from 9.29 to 9.3 and the install looks like it was successful but when the box reboots the console is stuck at the grub prompt - that is, the non-booting grub2> with no choices available.

I've been booting from a 32g USB stick. Any ideas to try and correct this or is there any issue with just attempting a clean 9.3 install? Thank you.

Clean install, import your pool and restore your system file which you should have backed up

Thank you.

That did it. I see nothing in the logs as to why I was having trouble but a clean install and importing my config seems to have done the trick. Thanks again.
