Encrypted zfs?

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
scrub: resilver completed with 0 errors on Wed Aug 29 12:23:52 2007
config:
NAME STATE READ WRITE CKSUM
z ONLINE 0 0 0
raidz1 ONLINE 0 0 0
label/0.eli ONLINE 0 0 0
label/1.eli ONLINE 0 0 0
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?
