At a first glance I do not see an easy way to roll back my pool to a slightly previous (consistent) state, but all the posts state that it is possible. I guess I have to dive into this a bit deeper. "zpool clear -F" definitely would be the easier-to-use solution.

But thanks for the hint, anyway. I will have a look around how difficult it is to get recent OpenSolaris on a USB stick... cu Gerrit
