Hi,
Is there a way to see which files have been deduped, so I can copy them again an un-dedupe them?
unfortunately, that's not easy (I've tried it :) ). The issue is that the dedup table (which knows which blocks have been deduped) doesn't know about files. And if you pull block pointers for deduped blocks from the dedup table, you'll need to backtrack from there through the filesystem structure to figure out what files are associated with those blocks. (remember: Deduplication happens at the block level, not the file level.) So, in order to compile a list of deduped _files_, one would need to extract the list of dedupes _blocks_ from the dedup table, then chase the pointers from the root of the zpool to the blocks in order to figure out what files they're associated with. Unless there's a different way that I'm not aware of (and I hope someone can correct me here), the only way to do that is run a scrub-like process and build up a table of files and their blocks.
