Trying to boot FreeBSD 11.0 RELEASE in UEFI mode after installing the OS
with root on a 4K native 2-disk ZFS mirror and getting the error below:
>> FreeBSD EFI boot block
Loader path: /boot/loader.efi
Initializing modules: ZFS UFS
Probing 14 block devices...........*.+ done
ZFS found the following pools zroot
UFS found no partitions

ZFS: i/o error - all block copies unavailable
ZFS: can't read MOS of pool zroot
Failed to load '/boot/loader.efi'

And the ZFS dataset:

The HDDs are 2 Tohsiba 4Kn spinning disks:
# camcontrol devlist

<TOSHIBA MG04ACA200A FP2A> at scbus7 target 0 lun 0 (ada0,pass1)

<Virtual CDROM 1.00> at scbus12 target 0 lun 0 (pass4,cd0)
<Virtual Floppy 1.00> at scbus12 target 0 lun 1 (da0,pass5)
The same setup on a Virtualbox VM is working fine.
Any idea what the issue might be?
Thanks,
