zfs discuss - Aug 2009 - strange zpool error "bad config type 16 for stats"

I have messed up the zpool on my fileserver.

It has 3 1TB disks in a z1 config.

root at metallica:~# zpool import -f

zdb: can''t open rzpool: No such file or directory

Not really sure where to go from here. From what I can read on this forum there
may still be a way to rescue the zpool by using a previous uberblock. Is this a
valid approach for this kind of error? And will zdb be able to do this
automatically with the use of dd and such?

I have not been able to find any solutions on the "bad config type 16 for
stats" error.

Any help and pointers is welcome.

Thanks
Bruno
