Let me try to refocus:
Given that I have a U4 system with a zpool created with Fletcher2:
What blocks in the system are protected by Fletcher2, or even
Fletcher4 although that does not worry me so much.
Given that I only have 1.6TB of data in a 4TB pool, what can I do to
change those blocks to sha256 or Fletcher4:
(1) Without destroying and recreating the zpool under U4
(2) With destroying and recreating the zpool under U4 (Which I don't
really have the resources to pull off)
(3) With upgrading to U7 (Perhaps in a few months)
(4) With upgrading to U8
This has been answered several times in this thread already.
set checksum=sha256 filesystem
copy your files -- all newly written data will have the sha256
checksums.
