My guess - there is a work-around or two, but you'll face a lot more grief, long-term, if you don't do things the right way (aka do a bunch of re-install work) now.

I'd start with 'gpart backup da0' (guessing that gpt/disk0 is on da0), to see how the original disk is partitioned. Then duplicate that partitioning on da1 and da2.

Hi guys,

Thank your for your answer.

@Ricchard First of all I didn't have a chance to run zpool upgrade, because
after the system update reboot i ran into the issue.

@Walter and @mike Regarding making a partition, I never see any
recommendation about this, I've been always using the entire disk on a pool
to expand it. Until FreeBSD 11.2 it worked fine.

Is there a workaround for this or should I reinstall the entire pool?

Just a guess, Is your VM still trying to boot from whatever gpt/disk0 is
? Or is it perhaps trying to boot from da1 or da2 which does not have
boot info ?  Generally its not recommended to use the entire disk as
part of a pool. Create a partition scheme first

gpart create -s gpt da1

gpart add -t freebsd-zfs da1

then add da1p1 to the pool
