Hi,
I have a customer with the following question...
She's trying to combine 2 ZFS 460gb disks into one 900gb ZFS disk. If
this is possible how is this done? Is there any documentation on this
that I can provide to them?

zpool replace == zpool attach + zpool detach
It is not a good practice to detach and then attach as you
are vulnerable after the detach and before the attach completes.
It is a good practice to attach and then detach. There is no
practical limit to the number of sides of a mirror in ZFS.

Ok, now its seems like its working what I wanted to do:
bash-3.00# zpool status
pool: mypool
state: ONLINE
scrub: resilver completed with 0 errors on Thu May 31 23:01:09 2007
config:
NAMESTATE READ WRITE CKSUM
mypool ONLINE 0 0 0
mirror
yeah it does something funky that I did not expect, zpool seems like its taking
slice 0 of that emc lun rather than taking the whole device...
so when I did create that lun, I formated disk and it looked like this:
format> verify
Primary label contents:
Volume name = <>
ascii name =
ok, I think I did figure out what is the problem
well what zpool does for that emc powerpath is it takes parition 0 from disk and
is trying to attach it to my pool, so when I added emcpower0a I got the
following:
bash-3.00# zpool list
NAMESIZEUSED AVAILCAP HEALTH

Yes by my goal is to replace exisiting disk which is internal disk 72gb with SAN
storage disk which is 100GB in size... As long as I will be able to detach the
old one then its going to be great... otherwise I will be stuck with one
internal disk and oneSAN disk which I do not like that much to

so I do run replace command and I get and error:

cannot replace c1t2d0 with emcpower0a: device is too small
Try "zpool attach mypool emcpower0a"; see

Hmm, I am having some problems, I did follow what you suggested and here is what
I did:

pool: mypool
state: ONLINE
scrub: none requested
config:
