Yep, using GELI the providers is much better.

I decided to go one step further and run GLABEL on my drives so my ZFS
pool will be immune from device enumeration issues (assuming I move the
drives between systems, SATA raid cards, etc.)

The only thing that sucks is that once I have attached all GELI
providers, I have to manually kickstart zfs and mount the pool with the
following commands:-

# kldload zfs
# zfs volinit
# zfs mount -a

  pool: z
 state: ONLINE

	    label/2.eli  ONLINE       0     0     0
	    label/3.eli  ONLINE       0     0     0

errors: No known data errors

One thing I also tried was replacing a drive with a much larger one
using zpool replace. ZFS didn't notice the larger disk capacity of the
new drive and subsequently didn't increase the pool size. What is the
logic behind that?
