In the past when replacing a disk in a zfs pool that I boot from, simply doing gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0 where p1 = freebsd-boot p2 = freebsd-swap p3 = freebsd-zfs works just fine (ie. replacing ada0). However, on this one box, I noticed the disk has both freebsd-boot and efi p1 = efi p2 = freebsd-boot p3 = freebsd-swap p4 = freebsd-zfs If I replace ada0, what do I need to do in order to full restore boot functionality to the disk ? gpart bootcode -b /boot/pmbr -p /boot/boot1.efifat -i 1 ada0 gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 2 ada0 vs gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0 ? And is it boot1.efi or boot1.efifat ? I am guessing I also need the lable ? gpart modify -l efiboot2 -i 1 ada0 e.g. current ada0 is Geom name: ada0 modified: false state: OK fwheads: 16 fwsectors: 63 last: 976773127 first: 40 entries: 128 scheme: GPT Providers: 1.
