Installed FreeBSD14.2p0 today (2025.01.12) on a machine in UEFI only mode (no
dual or BIOS boot option). And only one of the 2 disk zfs mirror (ada0) has the
necessary 'stuff' in the EFI partition to boot if one of the two drives is
gone.
tried: dd if=/dev/ada0p1 of=/dev/ada1p1 bs64k
but booting on ada1 with ada0 disconnected resulted in an aborted boot
Before this bug is fixed (hopefully) and the installer does the right thing and
makes all disks in a mirror bootable, is there a work-around? What can I do to
my other disk to make the system boot if the other disk in the mirror
disappears?
for reference, here's the result of gpart show
root@ABCH040:~ # gpart show ada0 ada1
=> 40 125045344 ada0 GPT (60G)
40 532480 1 efi (260M)
