ZFS recovery after power failure

[Sergey Gavrilov]

I've destroyed 2 latest uberblocks and imported pool. It's ok now.
Your command don't work for me as is, but all tgx nubmers of all labels are
the same and equal 666999 now.
Think it's already useless information.
So I saved those uberblocks. I can provide them if you need.
