I have a ZFS raid with 4 samsung 500GB disks. I now want 5 drives samsung 1TB
instead. So I connect the 5 drives, create a zpool raidz1 and copy the content
from the old zpool to the new zpool.
Is there a way to safely copy the zpool? Make it sure that it really have been
copied safely?

release you are running, you might need to export/import
Additional comment:
zfs receive verifies the data sent. It also can maintain the snapshots,
which
is handy.
rsync will also verify the data sent between source and destination. rsync
doesn't know anything about snapshots, though it might be a best practice
to use a snapshot as an rsync source.
Cindy and you all, thanx for your answers! I have got us several more
OpenSolaris converts meanwhile. One guy said, Why didnt I try ZFS before?? :o)
A quick question, in scenario A)
My old 4 samsung 500GB is a raidz1. If I exchange each drive and finally add a
hot spare, it is not the same
Hi Orvar,
Option A effectively doubles your existing pool (500GB x 4--1TB x 4)
*and* provides increased reliability. This is the difference between
options A and B.
I also like the convenience of just replacing the smaller disks with
larger disks in the existing pool and not having to create a
