Re: [zfs-macos] Weird I/O block
Based on what you posted earlier, you’re still seeing lots of read and write errors after replacing the cables, so I highly doubt those were really the root of your problem.

Can you try connecting these to a different machine, and/or via either eSATA or USB 2.0?

Re: [zfs-macos] Weird I/O block
Really, though, it looks like there’s a bunch of reviews online (Amazon, Newegg, …) that mention stability issues with these boxes, drives dropping out under load and USB 3 flakiness. If these are indeed accurate (I don’t have any personal experience with them), I’m not surprised you’d run into issues with ZFS.

Re: [zfs-macos] Weird I/O block
On another note, never scrub if your not sure what's wrong. A little more detail. I have recently seen what your encountering several times. It was at least one faulty cable in each case once it was two. Once fixed everything was perfect. Yes the -v fails, been that way for awhile now concerning permissions.
