Hi, I have a server with 4 disks with most of the disk as a 4-way ZFS root partition, and small EFI, freebsd-boot (as an emergency backup) and swap partition. For some reason the EFI partitions seem to have gotten corrupted in one of the updates, so the server simply refuses to boot using UEFI, and when trying to boot using BIOS booting, it complains about the efi partition being corrupted (and trying to mount it as a msdos partition results in failure as the partition is not valid. What would be the easiest way to recreate the boot partitions without affecting the ZFS partitions)? Julf
