21.06 Upgrade errors

[SAINT]

Hi everyone,

I've decided to give SCALE a go and I'm trying to upgrade to 21.06 from CORE 12. Following the steps in the getting started guide when I proceed with the upgrade, it always terminates with the following error:

Code:

cannot create 'boot-pool/grub': dataset already exists

[0%] Creating dataset

[0%] Extracting

[90%] Extracting

[90%] Performing post-install tasks

Error: Command ['chroot', '/tmp/tmpvm64487u', 'update-grub'] failed with exit code 1: /usr/sbin/grub-probe: error: failed to get canonical path of /dev/sdh2'.

The TrueNAS upgrade on sdc has failed. Press enter to continue...

Can anyone tell me what's happening? I can't seem to find this issue reported anywhere else.

As a bit extra, this is the guide I started following when I was having problems, under "Migrating from TrueNAS CORE"

/scale/gettingstarted/install/installingscale/

I've tried to upgrade my install, as well as doing a fresh install. I've also tried to installing in a new boot environment, as well as formatting the boot device. I get the same error regardless.
