problem booting from 2nd drive

[Christos Chatzaras]

I used dump/restore commands to copy a custom freebsd 11.1 to a new server. After I restore the files I create gmirror (RAID-1) and copy the bootcode to both disks:

gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ada0
gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ada1

When I select from BIOS to boot using 1st disk (ada0) then it boots without issue. If I select to boot from 2nd disk (ada1) then it hangs and restarts again and again.

The message I get during boot is:

gptboot: invalid primary GPT header
gptboot: invalid backup GPT header
gptboot: unable to load GPT


Any idea what the issue could be?
