The reason I'd recommend 512k for boot is to provide room for expansion
moving forward, as repartitioning to upgrade is a scary / hard thing to do.
Remember it wasn't long ago when it was well under 64k and that's what was
recommend, its not like with disk sizes these days you'll miss the extra
384k ;-)
Yeah, that's wise you're right.
Boot to a live cd, I'd recommend mfsbsd, and make sure the boot loader was
written to ALL boot disks correctly e.g.
if you have a mirrored pool with ada0 and ada1:
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0
If this doesn't help the output from gpart show, uname -a and zpool status
would also be helpful.
This is all assuming standard BIOS mode and not UEFI which is done
differently.
I just use the installation media on an USB key and then drop to the
shell. This is a full FreeBSD running, so that's fine.
% # gpart show ada0
% => 40 312581728 ada0 GPT (149G)
% 40 1024 1 freebsd-boot (512K)

Here are the steps to write the bootloader:
% # gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0
% partcode written to ada0p1
% bootcode written to ada0
% # zpool get bootfs zroot
% NAME PROPERTY VALUE SOURCE
% zroot bootfs zroot local
Two things spring to mind
Idea 1:
Is your root fs actually your direct pool or is it actually /root off
your pool.
If so you want to run:
zpool set bootfs=zroot/root zroot
Idea 2:
You mentioned in your original post and you used zfs send / recv to
restore the pool, so I wonder if your cache file is out of date.
Try the following:
|zpool export zroot
zpool import -R /mnt -o cachefile=/boot/zfs/zpool.cache zroot
cp /boot/zfs/zpool.cache /mnt/boot/zfs/zpool.cache
zpool set bootfs=zroot/root zroot
