Re: Zpool doesn't boot anymore after FreeBSD 12.1

There are few issues. with vmware, you should rather grow existing boot disk - just to keep setup simple. If you are adding disks, make sure they are properly partitioned.

int13 error code 4 should be ’sector not found’, I have no idea why are you getting this one, but clearly there is something wrong.

I would fix this by adding new properly sized disk, boot from iso/usb and create new zroot pool and copy data over from old and move old one away. once you have verified boot from new zroot, you can clean up.
