I did extensive testing of the new(er) multipath code earlier  
(January-March) this year before putting our ZFS SANs into production. I  
was never able to produce corruption by breaking the multipath during my  
tests. There would be errors, but it always seemed to recover. I also  
would have expected ZFS to notice write errors or something during  
scrubbing.

Hopefully this info is useful to someone out there...
