zfs discuss - Dec 2009 - Can I destroy a Zpool without importing it?

Hi, in the process of building a new fileserver and I''m currently
playing around with various operating systems, I created a pool in Solaris,
before I decided to try OpenSolaris aswell, so I installed OpenSolaris 20009.06,
but I forgot to destroy the pool I created in Solaris, so now I can''t
import it because it''s a newer version of ZFS in Solaris then it is in
OpenSolaris.

And I can not seem to find a way to destroy the pool without importing it first.
I guess I could format the drives in another OS, but that is alot more work then
it should be. Is there any way to do this in OpenSolaris?

opensolaris has a newer version of ZFS than Solaris. What you have is
a pool that was not marked as exported for use on a different OS
install.

Simply force import the pool using zpool import -f

Also, if you don''t care about the existing pool and want to create a
new pool one the same devices, you can go ahead and do so.

The format command will list the storage devices available to you.

Are there any negative consequences as a result of a force import? I mean

If the pool is not in use, no.  It''s a safety check to avoid problems
that can easily crop up when storage can be seen by multiple machines.

If your pool is imported on machine A and you force import it on machine
B at the same time, you will corrupt the pool.
