I will also add that I haven't found a spare Intel PCIe card yet and I'll probably have to buy one.
But here's something I did do: I destroyed the ZFS volume, restarted the server, created a new ZFS volume, added my datasets to it just as they were before and ran another copy of rsync. This time it ran completely successfully. I even went ahead and did another drag and drop within the File Manager of the same files from an earlier post I made (that had failed several times) and that copied flawlessly too. Permissions/other settings are identical if I look at each configuration that I had made.
Feel free to add any further comments you may have.
I'm not going to mark this as solved yet because I'm not sure if this is just a fluke. I'll post back with more results as I continue to use the server.
