There is zpool scrub.  It will check all the checksums previously
calculated, verifying the data that was actually written is the data ZFS
previously thought it wrote.  If you have sufficient redundancy (mirror or
raid) it will self-correct any errors it finds.

Since you're experincing corruption that doesn't go away, I'm supposing you
don't have redundancy, or else the corruption happened in something higher
up, such as a failing cpu or non-ecc ram, or a flaky disk controller.

In any event, do you have any reason to believe you've eliminated the cause
of the corruption?  The behavior you're experiencing is normal if you have
failing hardware.
