Hi Daniel,
No conversion from a mirrored to RAIDZ configuration is available yet.
Mirrored pools are more flexible and generally provide good performance.
You can easily create a mirrored pool of two disks and then add two
more disks later. You can also replace each disk with larger disks
if needed. See the example below.
If you consider that disks are relatively inexpensive, then a mirrored
configuration is a very good option.
Thanks,
Cindy

Hello,
I'm about the build a opensolaris NAS system, currently we have two drives and
are planning on adding two more at a later date (2TB enterprise level HDD are a
bit expensive!).
Whats the best configuration for setting up these drives bearing in mind I want
to expand in the future?
I was thinking of mirroring the drives and then converting to raidz some how?
It will only be a max of 4 drives, the second two of which will be bought later.
Any ideas?
