Re: Reconstruct aggregates on diskpools

Steffan,

Reconstruction is only done when the input and output pools are both
sequential.  If you have 4.2 you can migrate the diskpool down to 0 to a 
tapepool,
then do a move data with 'reconstruct=yes' to another tape in the pool,
then do move data back to the diskpool.  If you aren't running 4.2 this is much 
harder
since only reclaim will do reconstruction but the tape must be full to be a
reclaim candidate.
