I'd start by questioning your filesystem -- quite frankly, if it's
reiserfs, you're better off just wiping it out and starting over; it has
an unnerving propensity to reconnect files to the tree in bizarre ways and
it's particularly vulnerable (and difficult to recover from) damage.

If you're not running xfs or jfs, it's probably a good time to seriously
rethink your choice of file system.

On general principle, I'd recommend wiping out the pool and starting over,
since if you can't trust your filesystem, how can you trust your backups? 
(You weren't specific about what kind of rsync errors you're getting, but
if it's related to a corrupt pool, by all means, clear out the pool.)
