zfs discuss - Oct 2010 - Mirroring a zpool

I have a raidz2 zpool which I would like to create a mirror of.

Is it possible to create a mirror of a zpool?

I know I can create multi way mirrors of vdevs, do zfs/send receive etc.. to
mirror data.   But can I create a mirror at the zpool level?

Thanks

Hi SR,

You can create a mirrored storage pool, but you can''t mirror
an existing raidz2 pool nor can you convert a raidz2 pool
to a mirrored pool.

You would need to copy the data from the existing pool,
destroy the raidz2 pool, and create a mirrored storage
pool.
