Hello,
I installed to a single disk with "/" on ZFS. After using "dd" to mirror the partitions from disk one to disk two, I added the second disk, ada1s1d, to the zfs pool.
# zpool status
pool: tank0
state: ONLINE
scan: resilvered 7.81G in 0h3m with 0 errors on Wed Sep 17 12:55:46 2014
config:
NAME STATE READ WRITE CKSUM
tank0 ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
ada0s1d ONLINE 0 0 0
ada1s1d ONLINE 0 0 0
<end>
The following is mounted;
# mount
tank0 on / (zfs, local, noatime, nfsv4acls)
devfs on /dev (devfs, local, multilabel)
/dev/label/boot0 on /boot-mount (ufs, local, noatime)
procfs on /proc (procfs, local)
linprocfs on /compat/linux/proc (linprocfs, local)
tank0/usr on /usr (zfs, local, noatime, nfsv4acls)
tank0/var on /var (zfs, local, noatime, nfsv4acls)
<end>
This is the output of gpart show;

t# gpart show

<end>
The problem is that I cannot boot from the 2nd disk. I see that /boot-mount is UFS, so I must have missed a step, or more, in getting the 2nd disk bootable. I get the following error when booting from it.
<snip>
Trying to mount root from zfs:tank0:[]...
Mounting from zfs:tank0 failed with error 2
Load variables
vfs.root.mountfrom=zfs:tank0
<snip>
Any ideas on how I can get the 2nd disk to boot? (Sorry for the long post)
Thank you in advance.
James
